GROWTH AND DEVELOPMENT IN CHILDREN

Complete 50-Mark Answer | Child Health Nursing (INC Pattern)

INTRODUCTION

SECTION 1: PRINCIPLES OF GROWTH AND DEVELOPMENT

1. Cephalocaudal direction - development proceeds from head downward (a baby controls head before trunk before legs)
2. Proximodistal direction - development proceeds from center outward (trunk control before arm before finger control)
3. Simple to complex - a child crawls before walking, babbles before speaking
4. General to specific - gross motor before fine motor
5. Continuous but uneven - growth is a continuous process but the rate varies; fastest in fetal life, first year, and puberty
6. Sequential and predictable - milestones follow a fixed sequence; a child never skips stages
7. Individual variation - each child has their own pace; milestones are averages not rigid rules
8. Interrelated aspects - physical, mental, social, and emotional development influence each other

SECTION 2: DETERMINANTS (FACTORS AFFECTING GROWTH & DEVELOPMENT)

A. Biological/Internal Factors

B. Environmental/External Factors

SECTION 3: PHYSICAL GROWTH PARAMETERS

A. Weight

• Birth weight: 2.5 - 3.5 kg (average 3 kg)
• Formula for expected weight:
  • Up to 6 months: Birth weight + (Age in months × 600 g)
  • 6-12 months: Birth weight + (Age in months × 500 g)
  • 1-6 years: Age (years) × 2 + 8 kg
  • 7-12 years: Age (years) × 7 - 5 / 2

• Birth weight doubles by 5 months
• Birth weight triples by 1 year
• Birth weight quadruples by 2 years

B. Height (Length)

• Birth length: ~50 cm
• Increases by 25 cm in 1st year
• Increases by 12 cm in 2nd year, then 9, 7, 6 cm each year up to 5 years
• Formula: Height = Age (years) × 6 + 77 cm (for 2-12 years)
• Adult height: Boys reach 98% adult height by 17.75 years; Girls by 16.5 years

C. Head Circumference

• Birth: 33-35 cm (average 34 cm)
• 6 months: 43 cm
• 1 year: 46-47 cm
• 2 years: 48 cm
• Adult: 55-58 cm
• Head circumference > chest circumference up to 1 year; they equalize at 1 year; after that chest > head

D. Chest Circumference

• Birth: 30-33 cm (about 2 cm less than head circumference)
• Equals head circumference at 1 year
• Exceeds head circumference after 1 year

E. Anterior Fontanelle

• Diamond-shaped, at junction of coronal and sagittal sutures
• Size at birth: 2-3 cm
• Closes at 12-18 months (up to 2 years is acceptable)
• Bulging = raised ICP (meningitis, hydrocephalus)
• Sunken = dehydration

F. Posterior Fontanelle

• Triangular-shaped
• Closes at 6-8 weeks (2 months)

SECTION 4: DEVELOPMENTAL MILESTONES (Age-Wise - Most Exam-Tested)

FOUR AREAS OF DEVELOPMENT (Gesell's 4 Streams):

1. Gross motor - posture, locomotion
2. Fine motor / Adaptive - hand-eye coordination, manipulation
3. Language - communication
4. Personal-social - interaction, self-care

MILESTONE TABLE

SECTION 5: PRIMITIVE REFLEXES

SECTION 6: THEORIES OF DEVELOPMENT

A. Sigmund Freud - Psychosexual Theory

B. Erik Erikson - Psychosocial Theory (Most Important for Nursing)

C. Jean Piaget - Cognitive Development Theory

D. Lawrence Kohlberg - Moral Development Theory

E. Gesell's Normative/Maturation Theory

• Development depends on neurological and physical maturation
• Universal, sequential progression of milestones
• Minimal role of environment
• Basis for developmental milestone charts used clinically (Textbook of Family Medicine 9e, Table 22-9)

SECTION 7: DENTITION

Primary (Deciduous) Teeth - 20 total

Permanent Teeth - 32 total

• First permanent molar: 6 years (6-year molar)
• All permanent teeth by 21 years

SECTION 8: DENVER DEVELOPMENTAL SCREENING TEST (DDST)

• Developed by Frankenburg and Dodds (1967), revised as Denver II (1992)
• Used to screen children 0-6 years for developmental delays
• Tests 4 domains: personal-social, fine motor-adaptive, language, gross motor
• Each item: tested by observation, parent report, or direct elicitation
• Each item represented as a bar spanning the age range when 25%, 50%, 75%, and 90% of children pass
• Interpretation:
  • Normal: No delays, at most one caution
  • Suspect: Two or more cautions or one delay
  • Untestable: Refusal to perform key items
• Nursing use: Screening tool only - not diagnostic; abnormal result requires full evaluation

SECTION 9: GROWTH CHARTS

• Road-to-health chart (Morley): Monitors weight gain over time
• India adopted WHO Child Growth Standards (2006) in February 2009
• Used in ICDS and National Rural Health Mission
• Three growth curves: General body growth, brain/head growth (rapid in preschool years), reproductive system growth (rapid at puberty)

Nutritional Classification Using Anthropometry

SECTION 10: PLAY AND ITS IMPORTANCE IN DEVELOPMENT

Types of Play (Parten's Classification)

Other Classifications

• Dramatic/Symbolic play - pretend play (preschool)
• Constructive play - building, creating
• Games with rules - school age

Therapeutic Benefits of Play

• Physical: develops motor skills and coordination
• Cognitive: encourages problem-solving and creativity
• Emotional: outlets for fear, anxiety, and tension
• Social: teaches sharing, cooperation, and empathy
• Therapeutic play in hospitals reduces fear and facilitates cooperation

SECTION 11: NURSING IMPLICATIONS

1. Assessment: Use age-appropriate developmental screening tools (DDST) in all routine child visits
2. Health promotion: Educate parents on expected milestones at each age; avoid comparing children
3. Anticipatory guidance: Prepare parents for upcoming developmental stages and safety concerns (e.g., childproofing at crawling stage)
4. Hospitalized children: Maintain developmental routines; provide age-appropriate play; minimize separation anxiety (most intense at 6 months - 3 years)
5. Stimulation: Educate parents on importance of talking, reading, and playing with children to promote development
6. Red flags: Refer for evaluation if a child loses previously gained milestones or significantly lags behind (e.g., not walking by 18 months, no words by 15 months)
7. Growth monitoring: Plot on WHO growth chart at every visit; three consecutive downward crossings of growth percentile lines is significant

SECTION 12: DEVELOPMENTAL RED FLAGS (Danger Signs)

CONCLUSION

Exam tip: For 50-mark answers, always include: definition, principles, factors, physical parameters with formulas, milestone table (4 streams), primitive reflexes, developmental theories (Erikson + Piaget are most important), DDST, growth chart, play types, nursing implications, and red flags. Each section alone can carry 5-8 marks.

Definition

Temperature Requirements

Freeze-Sensitive Vaccines (Must NOT be frozen)

• Hepatitis B, DPT, TT, DT, Td
• Pentavalent, IPV, PCV, HPV, Influenza

Cold Chain Equipment (Level-wise)

Key Cold Chain Points

• ILR (Ice-Lined Refrigerator): Most important at PHC level; maintains temperature even during power cuts for 6-8 hours due to ice lining
• Deep Freezer: Top-opening lid (prevents cold air loss); used for OPV and freezing ice packs
• WIF provides 72 hours of holdover time after power failure
• Vaccine Vial Monitor (VVM): Heat-sensitive label on vials; inner square darker than outer circle = vaccine unusable

SECTION 7: VACCINE STORAGE - KEY RULES

1. Store vaccines at the back of the refrigerator (not the door - temperature fluctuates)
2. Never store vaccines at the bottom of the refrigerator (risk of freezing)
3. Always store diluents with the vaccine (they must be reconstituted at the same temperature)
4. OPV at the top; freeze-sensitive vaccines in the middle
5. Keep vaccines away from the freezer compartment
6. Monitor temperature twice daily; record in temperature monitoring chart
7. Never use a domestic refrigerator for vaccine storage

SECTION 8: OPEN VIAL POLICY

• Expiry date has not passed
• Vaccines are stored at appropriate temperature
• Vaccine vial monitor has not crossed the discard point

• Exception: BCG, measles/MR, and any reconstituted vaccine must be discarded at end of session (within 4 hours of reconstitution)

SECTION 9: ADVERSE EVENTS FOLLOWING IMMUNIZATION (AEFI)

Definition

Classification of AEFI

Common AEFI by Vaccine

Management of AEFI

1. Assess severity
2. Immediate treatment (e.g., adrenaline for anaphylaxis)
3. Report to district/state AEFI committee within 24 hours
4. Investigate using standard checklist
5. Document and submit report

SECTION 10: MISSION INDRADHANUSH

• Launched: December 25, 2014 by Government of India
• Goal: Fully immunize all children (0-2 years) and pregnant women who are left out or dropped out from routine immunization
• Targets: Districts with low immunization coverage (< 50%)
• Intensified Mission Indradhanush (IMI): Launched 2017, targets to reach 90% full immunization coverage
• SAANS Campaign and Har Ghar Dastak campaigns supplemented it

SECTION 11: HERD IMMUNITY

• Definition: Indirect protection to unimmunized individuals in a population when a sufficient proportion is immunized
• Herd immunity threshold: Varies by disease (measles ~95%, polio ~80-85%)
• Importance: Protects those who cannot be vaccinated (newborns, immunocompromised)
• Achieved when reproductive number (R0) falls below 1

SECTION 12: NURSING RESPONSIBILITIES IN IMMUNIZATION

Before Vaccination

1. Assess contraindications - high fever, severe allergic reaction to previous dose, immunocompromised state
2. Review immunization history and fill due vaccines
3. Check vaccine vial - VVM, expiry date, appearance
4. Prepare correct dose and diluent at room temperature (for live vaccines - reconstitute immediately before use)
5. Inform parent about the vaccine, its purpose, and possible side effects

During Vaccination

1. Confirm identity and age
2. Use correct site, route, dose, and technique
3. Use separate syringe and needle for each vaccine
4. Never mix vaccines in same syringe (unless licensed combination)

NURSING MANAGEMENT OF PRETERM / LOW BIRTH WEIGHT (LBW) BABY

Complete 50-Mark Answer | Child Health Nursing (INC Pattern)

INTRODUCTION

SECTION 1: DEFINITIONS AND CLASSIFICATION

A. Classification by Birth Weight

B. Classification by Gestational Age

C. Classification by Intrauterine Growth

D. Types of LBW

1. Preterm AGA - born early but weight appropriate for gestational age (prematurity is the cause)
2. Term SGA (IUGR) - born at term but small due to placental insufficiency or other causes
3. Preterm SGA - both premature and growth restricted (worst prognosis)

SECTION 2: CAUSES / ETIOLOGY

A. Causes of Preterm Birth

• Preeclampsia and eclampsia
• Infections (UTI, chorioamnionitis, TORCH infections)
• Cervical incompetence
• Uterine abnormalities (bicornuate uterus)
• Previous preterm delivery
• Multiple pregnancy (twins, triplets)
• Polyhydramnios
• Antepartum hemorrhage (placenta previa, abruption)
• Anaemia, malnutrition
• Age extremes (< 18 years or > 35 years)

• Congenital anomalies
• Multiple gestation
• IUGR

• Poverty, malnutrition
• Inadequate antenatal care
• Hard physical labor
• Smoking, alcohol, drug abuse

B. Causes of IUGR/SGA

• Placental insufficiency (most common)
• Maternal hypertension, preeclampsia
• TORCH infections
• Chromosomal abnormalities
• Maternal smoking, alcohol, substance abuse
• Multiple pregnancy

SECTION 3: PHYSICAL CHARACTERISTICS OF A PRETERM BABY

SECTION 4: PROBLEMS OF PRETERM / LBW BABY

A. Thermoregulation Problems

• Thin skin with poor insulating subcutaneous fat
• Large body surface area relative to body weight (rapid heat loss)
• Immature hypothalamic thermoregulation center
• Poor flexion posture (more body surface exposed)
• Absent/minimal brown adipose tissue (main source of non-shivering thermogenesis)
• Result: Hypothermia - most common and dangerous problem

B. Respiratory Problems

• Respiratory Distress Syndrome (RDS / Hyaline Membrane Disease): Deficiency of surfactant (produced by Type II pneumocytes, matures after 35 weeks); leads to alveolar collapse, progressive atelectasis
• Apnea of prematurity: Cessation of breathing > 20 seconds or < 20 seconds with bradycardia/cyanosis - due to immature respiratory center
• Weak respiratory muscles, poor chest wall compliance

C. Feeding / Nutritional Problems

• Absent or poor sucking and swallowing reflex (matures at 32-34 weeks)
• Small stomach capacity
• Poor gut motility; immature enzyme systems
• Gastroesophageal reflux
• Risk of Necrotizing Enterocolitis (NEC) - ischemic, inflammatory bowel necrosis; hallmark: pneumatosis intestinalis on X-ray

D. Neurological Problems

• Intraventricular Hemorrhage (IVH): Bleeding into germinal matrix → ventricles; most common in < 32 weeks; leads to hydrocephalus, cerebral palsy
• Periventricular Leukomalacia (PVL): White matter injury; major cause of cerebral palsy
• Hypoxic-Ischemic Encephalopathy (HIE)
• Seizures
• Long-term: cognitive delay, learning disabilities, behavioral problems

E. Metabolic Problems

• Hypoglycemia: Most common metabolic problem; blood glucose < 45 mg/dL (or < 40 mg/dL in neonates per some guidelines); due to low glycogen stores and hyperinsulinism
• Hypocalcemia: Serum calcium < 7 mg/dL; causes jitteriness, seizures
• Hyponatremia, Hypokalemia
• Metabolic acidosis

F. Hematological Problems

• Anemia of prematurity: Low erythropoietin production; iatrogenic blood loss from sampling
• Hyperbilirubinemia (Jaundice): Immature liver; inadequate conjugation; exaggerated physiological jaundice - risk of kernicterus
• Disseminated Intravascular Coagulation (DIC)

G. Infection / Sepsis

• Immature immune system (low IgG, poor phagocytosis, skin barrier immature)
• Neonatal sepsis: Most common organisms - Group B Streptococcus (early onset), Staphylococcus, E. coli (late onset)
• Risk of fungal infections (Candida)

H. Cardiovascular Problems

• Patent Ductus Arteriosus (PDA): Failure of ductus to close; causes left-to-right shunt, pulmonary edema; treated with indomethacin (prostaglandin inhibitor) or surgical ligation

I. Ophthalmic Problems

• Retinopathy of Prematurity (ROP): Abnormal vascularization of retina due to oxygen toxicity; leading cause of preventable blindness in preterm infants; screen all infants < 32 weeks or < 1500 g

J. Renal Problems

• Immature kidneys; cannot concentrate or dilute urine effectively
• Risk of fluid and electrolyte imbalance

SECTION 5: ASSESSMENT OF THE PRETERM / LBW BABY - APGAR SCORE

• 7-10: Normal
• 4-6: Moderate depression - requires stimulation and oxygen
• 0-3: Severe depression - requires immediate resuscitation

SECTION 6: NURSING MANAGEMENT

A. IMMEDIATE CARE AT BIRTH (The 6 Warmth Steps + ABCD)

1. Warm - Pre-warm radiant warmer to 35-36°C before delivery; place baby under radiant warmer immediately
2. Dry - Dry immediately and thoroughly with warm towel; remove wet linen
3. Stimulate - Rub back and soles of feet
4. Position - Sniffing position (neck slightly extended)
5. Clear airway - Suction if meconium or secretions present (mouth before nose)
6. Assess - Breathing, heart rate, color at 1 minute (Apgar)

B. THERMOREGULATION (MOST IMPORTANT)

1. Radiant warmer (open care system): For sick/very preterm infants; allows easy access; set servo-control to maintain skin temperature 36.5°C
2. Incubator/Isolette (closed incubator): For stable preterm babies; maintains warm, humid environment; reduces insensible water loss; temperature set according to weight and age
3. Kangaroo Mother Care (KMC): Skin-to-skin contact between mother/father and baby; baby placed on parent's bare chest vertically; maintains temperature, promotes bonding, breastfeeding; proven to reduce mortality in LBW
4. Warm room: Room temperature 25-28°C; avoid drafts
5. Warm clothing: Cap (prevents 20-25% heat loss from head), socks, double wrapping

C. RESPIRATORY SUPPORT

1. Position: Head slightly extended (sniffing position); prone position improves oxygenation but requires monitoring
2. Oxygen therapy: Maintain SpO₂ 91-95% in preterm infants (avoid hyperoxia → ROP; avoid hypoxia → brain damage)
3. CPAP (Continuous Positive Airway Pressure): First-line for RDS; maintains alveoli open; prevents atelectasis; nasal prongs
4. Mechanical ventilation: For severe RDS or apnea not responding to CPAP
5. Surfactant therapy: Exogenous surfactant (Poractant alfa - Curosurf; Beractant - Survanta) administered via endotracheal tube; dramatic improvement in RDS
6. Antenatal corticosteroids: Betamethasone or dexamethasone given to mother 24-48 hours before preterm delivery to accelerate fetal lung maturation and surfactant production
7. Apnea management: Caffeine citrate (methylxanthine) stimulates respiratory center; most effective treatment for apnea of prematurity

D. NUTRITION AND FEEDING

1. Direct breastfeeding: If > 34 weeks and sucking reflex present; best option
2. Expressed Breast Milk (EBM) via cup/spoon: For 32-34 weeks
3. Orogastric / Nasogastric (tube) feeding: For < 32 weeks or sick infants unable to suck; gavage feeding
4. Total Parenteral Nutrition (TPN): For very sick/very preterm infants who cannot tolerate enteral feeds; via central venous line

• Contains more protein and sodium than term milk
• Rich in IgA, growth factors, anti-infective factors
• Reduces risk of NEC by 6-10 times
• Promotes gut maturation

• Start early (within 1-2 hours of birth if stable)
• Begin with 1-2 ml/kg/feed every 2-3 hours
• Increase by 10-20 ml/kg/day as tolerated
• Monitor for feed intolerance (abdominal distension, vomiting, residual)

• Iron supplementation from 2 weeks of age (2-3 mg/kg/day)
• Vitamin D: 400-800 IU/day
• Calcium and phosphorus supplementation
• Human milk fortifier (HMF) added to breast milk for VLBW infants

E. PREVENTION AND MANAGEMENT OF INFECTION

1. Hand hygiene: Most important - wash hands before and after handling baby
2. Aseptic technique: Sterile gloves for procedures; proper cord care
3. Minimal handling: Cluster care to reduce disturbance
4. Restrict visitors and persons with infection
5. Early signs of sepsis in preterm: Lethargy, poor feeding, temperature instability, apnea, bradycardia, abdominal distension, jaundice
6. Blood culture before starting antibiotics
7. Empiric antibiotics: Ampicillin + Gentamicin for early-onset sepsis; Vancomycin + Gentamicin for late-onset
8. Monitor CBC, CRP for infection markers

F. FLUID AND ELECTROLYTE MANAGEMENT

• Insensible water loss (IWL) is very high in preterm (thin skin, large surface area, radiant warmers)
• Fluid requirement: 60-80 ml/kg/day on day 1; increase by 10-20 ml/kg/day; up to 150-180 ml/kg/day by end of first week
• Monitor urine output (target 1-3 ml/kg/hr); daily weight
• Monitor electrolytes daily: sodium, potassium, calcium, glucose
• 10% Dextrose as initial maintenance fluid; add sodium after first 24 hours

G. PREVENTION OF HYPOGLYCEMIA

• Blood glucose monitoring every 3-6 hours (especially first 24-48 hours)
• Start early enteral feeds; if not possible, IV dextrose
• Target blood glucose: 45-120 mg/dL
• Symptomatic hypoglycemia: IV 10% dextrose bolus 2 ml/kg, then continuous infusion

H. KANGAROO MOTHER CARE (KMC) - HIGH PRIORITY

1. Kangaroo position: Baby placed skin-to-skin vertically on mother's chest between the breasts; baby's head turned to one side, hips and knees flexed (frog position); covered with mother's clothes
2. Kangaroo nutrition: Exclusive breastfeeding or expressed breast milk
3. Kangaroo support: Early discharge with follow-up and support

• Haemodynamically stable baby
• No IV lines or if IV access maintained
• Baby tolerating enteral feeds
• Birth weight usually > 1000 g (can start even earlier in centers with expertise)

• Maintains temperature as effectively as incubator
• Promotes breastfeeding and bonding
• Reduces infection rates
• Reduces apnea episodes
• Accelerates neurological development
• Reduces mortality by 40% (WHO)
• Reduces length of hospital stay
• Cost-effective; especially valuable in resource-limited settings

• Teach mother the correct KMC position
• Monitor baby's temperature, breathing, feeding
• Support mother with breastfeeding
• Advise on hygiene and skin care
• Empower mother and build confidence

I. MONITORING

• Temperature every 3-4 hours (axillary 36.5-37.5°C)
• Heart rate (normal: 120-160/min)
• Respiratory rate (normal: 40-60/min)
• SpO₂ (target 91-95%)
• Blood glucose (every 3-6 hours initially)
• Urine output (measure via weighing diapers)
• Weight (daily - target gain 15-20 g/kg/day after regaining birth weight)
• Feed tolerance (residual, vomiting, abdominal distension)
• Signs of jaundice (transcutaneous bilirubinometry or serum bilirubin as needed)
• Signs of infection

J. RETINOPATHY OF PREMATURITY (ROP) SCREENING

• All infants < 32 weeks gestation or birth weight < 1500 g must be screened
• First screening: 4 weeks after birth
• Ophthalmologist performs indirect ophthalmoscopy
• Laser photocoagulation for Stage 3+ ROP

SECTION 7: NEONATAL RESUSCITATION (NRP)

• Position baby in sniffing position under radiant warmer
• Clear airway: suction if needed (mouth then nose)
• Dry and stimulate (rub back/soles)
• Reposition and reassess in first 30 seconds

• If not breathing or heart rate < 100 bpm: Positive pressure ventilation (PPV) with bag and mask
• Rate: 40-60 breaths/min; use 21% O₂ initially (room air); add oxygen if SpO₂ remains low
• Reassess after 30 seconds of PPV

• If heart rate < 60 bpm despite 30 seconds of adequate PPV: Start chest compressions
• Thumb technique (preferred): 2 thumbs on lower 1/3 of sternum, hands encircling chest
• Rate: 3 compressions: 1 breath = 90 compressions + 30 breaths/min
• Depth: 1/3 of chest AP diameter

• If heart rate remains < 60 bpm despite PPV + compressions:
• Adrenaline (Epinephrine): 0.1-0.3 ml/kg of 1:10,000 solution IV (via umbilical vein catheter)
• Normal saline (volume expander): 10 ml/kg if blood loss or shock

SECTION 8: COMPLICATIONS (Long-term)

SECTION 9: PREVENTION OF PRETERM BIRTH AND LBW

1. Antenatal care: Early booking, regular ANC visits
2. Nutrition: Adequate protein, iron, folic acid supplementation; prevent anemia
3. Folic acid: 400 mcg/day periconceptionally to prevent neural tube defects
4. Treat infections: UTI, TORCH, STIs
5. Cervical cerclage for cervical incompetence
6. Progesterone: Vaginal progesterone in women with short cervix or previous preterm birth
7. Tocolytics: Nifedipine, ritodrine to delay preterm labor (48 hours to allow steroid administration)
8. Antenatal steroids: Betamethasone 12 mg IM x 2 doses 24 hours apart to mother at 24-34 weeks; accelerates fetal lung maturation (most important antenatal intervention for preterm)
9. Spacing births: Birth spacing ≥ 2 years
10. Stop smoking, alcohol

SECTION 10: NURSING DIAGNOSES AND CARE PLAN

SECTION 11: DISCHARGE PLANNING AND CRITERIA

1. Baby able to maintain temperature in open cot (room temperature 25°C)

PROTEIN ENERGY MALNUTRITION (PEM) - KWASHIORKOR AND MARASMUS

Complete 50-Mark Answer | Child Health Nursing (INC Pattern)

INTRODUCTION

1. Marasmus - Severe acute malnutrition WITHOUT oedema (wasting)
2. Kwashiorkor - Severe acute malnutrition WITH oedema
3. Marasmic Kwashiorkor - Overlapping features of both

SECTION 1: DEFINITIONS

SECTION 2: CAUSES / ETIOLOGY

A. Primary Causes (Dietary)

1. Inadequate dietary intake - insufficient quantity and quality of food
2. Prolonged exclusive breastfeeding without timely complementary feeding
3. Weaning practices - abrupt weaning onto high-carbohydrate, low-protein diet (main cause of Kwashiorkor)
4. Poverty and food insecurity
5. Ignorance about nutrition and child feeding
6. Large family size with poor food distribution

B. Secondary Causes (Underlying Disease)

1. Recurrent infections - diarrhea, measles, respiratory infections increase requirements and reduce intake
2. Malabsorption - celiac disease, chronic diarrhea, parasitic infestations
3. Chronic illness - tuberculosis, HIV/AIDS, congenital heart disease
4. Prematurity and low birth weight
5. Wrong feeding practices - diluted formula feeds, "rice milk" diets

C. Social/Environmental Causes

• Low socioeconomic status
• Maternal malnutrition and anaemia
• Inadequate antenatal and postnatal care
• Cultural taboos regarding certain foods
• Lack of maternal education

SECTION 3: PATHOPHYSIOLOGY

Marasmus Pathophysiology

1. Body mobilizes fat stores first → loss of subcutaneous fat
2. Then mobilizes muscle protein (gluconeogenesis) → muscle wasting
3. Cortisol and growth hormone increase → catabolic state
4. Body weight falls to < 60% of expected weight
5. Albumin relatively maintained (protein-sparing adaptation) → NO oedema
6. Immune function severely impaired → recurrent infections

Kwashiorkor Pathophysiology

1. Adequate calories but protein severely deficient
2. Serum albumin falls markedly (< 2.5 g/dL) → reduced oncotic pressure → oedema
3. Superimposed acute illness/infection triggers stress response - blocks protein-sparing mechanisms
4. Free radical damage worsens tissue injury
5. Gut microbiome disruption (decreased anti-inflammatory taxa, increased inflammatory bacteria)
6. Fatty liver develops - protein deficiency impairs VLDL synthesis, fat cannot be exported from liver → hepatomegaly with fatty infiltration
7. Hair changes - hair becomes thin, sparse, discoloured (flag sign - alternating dark/light bands)

SECTION 4: CLINICAL FEATURES - DETAILED COMPARISON

MARASMUS

KWASHIORKOR

MARASMIC KWASHIORKOR

• Features of BOTH conditions present
• Severe wasting + bilateral oedema
• Worst prognosis of the three
• May occur when a marasmic child develops acute illness (infection)

SECTION 5: COMPARISON TABLE - KWASHIORKOR vs MARASMUS (Highest Exam Value)

SECTION 6: GRADING / CLASSIFICATION OF MALNUTRITION

A. Gomez Classification (Weight-for-Age)

B. Waterlow Classification (Weight-for-Height AND Height-for-Age)

• Wasting = low weight-for-height = acute/current malnutrition
• Stunting = low height-for-age = chronic/past malnutrition
• Underweight = low weight-for-age = acute + chronic combined

C. IAP Classification (Weight-for-Age)

D. WHO SAM Criteria (Used in IMNCI/Clinical Practice)

SECTION 7: INVESTIGATIONS

SECTION 8: WHO 10-STEP MANAGEMENT PROTOCOL FOR SAM

PHASE 1: STABILIZATION (Days 1-7) - Treat the child, NOT the malnutrition aggressively yet

• Blood glucose < 54 mg/dL = hypoglycaemia
• Give 10% glucose or 10% sucrose orally (50 ml) or IV if unconscious
• Start feeding 2-hourly (day and night) to prevent recurrence
• Monitor blood glucose

• Axillary temperature < 35°C = hypothermia
• Warm with clothes, blanket, skin-to-skin contact
• Kangaroo care for young infants
• Warm room (25-30°C); avoid wet clothes

• Do NOT use standard ORS in SAM - electrolyte imbalance already present
• Use ReSoMal (Rehydration Solution for Malnutrition) - lower sodium, higher potassium and magnesium
• ReSoMal: 5-10 ml/kg/hr for first 2 hours; then 5-10 ml/kg alternating with F-75 formula for next 4-10 hours
• Avoid IV fluids unless shock - very dangerous in SAM (risk of fluid overload and heart failure)

• Give extra potassium (3-4 mmol/kg/day)
• Give extra magnesium (0.4-0.6 mmol/kg/day)
• Reduce sodium (do NOT give salty food/saline)

• All SAM children assumed to have infection even without obvious signs
• Give broad-spectrum antibiotics: Amoxicillin oral OR Ampicillin + Gentamicin IV for 7 days
• Add Metronidazole if suspected gut infection
• Treat malaria, TB if present

• Vitamin A: Single high-dose (age-specific) on Day 1 unless given in last month
  • < 6 months: 50,000 IU
  • 6-12 months: 100,000 IU

  • 12 months: 200,000 IU

• Folic acid: 5 mg on Day 1; then 1 mg/day
• Zinc: 2 mg/kg/day for 2 weeks
• Copper: 0.3 mg/kg/day
• Iron: Do NOT give iron in Phase 1 (worsens infection by providing substrate for bacteria)
• Multivitamin supplement daily

• F-75: 75 kcal/100 ml; starter formula
• Feed 2-3 hourly (8-12 feeds/day); small amounts
• Total: 100 ml/kg/day initially
• Monitor for signs of heart failure (respiratory distress, increasing oedema)
• If child refuses to eat → nasogastric tube feeding

• Begins when: appetite returns, oedema reducing, no infection
• F-100: 100 kcal/100 ml; higher protein and energy
• Transition gradually over 2-3 days to avoid refeeding syndrome
• Increase volume by 10 ml/feed every 2 feeds until 150-220 ml/kg/day
• Target catch-up: 10-15 g/kg/day weight gain

• Tender loving care (TLC)
• Stimulating environment with toys, play
• Structured play therapy
• Maternal involvement and education

• Discharge when weight-for-height > -2 SD AND no oedema AND eating well
• RUTF (Ready-to-Use Therapeutic Food): Peanut-based paste; 500 kcal/sachet; 150 kcal/kg/day for 4-6 weeks in community
• Monthly follow-up for 6 months
• Immunization catch-up
• Feeding counseling

SECTION 9: NUTRITIONAL REHABILITATION CENTRE (NRC)

• Government-run facilities at district/sub-district hospitals
• For SAM children aged 6 months to 5 years without medical complications
• Free residential care for 14 days: medical treatment + therapeutic feeding
• Mother stays with child - learns feeding techniques
• RUTF provided on discharge
• Monthly follow-up for 3 months

• SAM (MUAC < 11.5 cm or WFH < -3 SD or bilateral pitting oedema)
• Medical complications (present → stabilization ward first)

SECTION 10: ASSOCIATED NUTRITIONAL DEFICIENCIES

A. Vitamin A Deficiency

NEPHROTIC SYNDROME IN CHILDREN

Complete 50-Mark Answer | Child Health Nursing (INC Pattern)

INTRODUCTION

Massive Proteinuria → Hypoalbuminemia → Generalized Oedema + Hyperlipidemia/Lipiduria

SECTION 1: DEFINITION

1. Massive (heavy) proteinuria: > 3.5 g/day in adults; > 40 mg/m²/hour or > 3+ protein on urine dipstick in children
2. Hypoalbuminemia: Serum albumin < 3 g/dL (< 2.5 g/dL is severe)
3. Generalised oedema (anasarca)
4. Hyperlipidaemia and lipiduria

SECTION 2: CLASSIFICATION / CAUSES

A. Primary (Idiopathic) - Most Common in Children

B. Secondary Causes

SECTION 3: PATHOPHYSIOLOGY (Step-by-Step Chain)

Step 1: Glomerular Basement Membrane (GBM) Injury

• The GBM normally acts as a size and charge barrier
• In MCD: Loss of polyanion (negative charge) on GBM → allows negatively charged albumin to pass through
• In other causes: structural damage + podocyte injury → increased permeability

Step 2: Massive Proteinuria

• Proteins (mainly albumin - smallest, most abundant) leak into Bowman's space

• 3.5 g/day in adults; > 40 mg/m²/hr in children

• Selective proteinuria (MCD): mainly albumin lost (selectivity index < 0.1)
• Non-selective proteinuria (FSGS, MPGN): large proteins (IgG, globulins) also lost

Step 3: Hypoalbuminemia

• Urinary albumin loss exceeds liver's compensatory synthetic capacity
• Increased renal catabolism of filtered albumin
• Serum albumin falls < 3 g/dL → < 2.5 g/dL in severe cases

Step 4: Oedema Formation (Underfill + Overfill theories)

• Low serum albumin → ↓ plasma oncotic pressure → fluid leaks into interstitium → ↓ intravascular volume → activates RAAS → aldosterone → Na and water retention → worsens oedema

• Primary sodium retention by diseased kidney → plasma expansion → oedema

• Oedema is characteristically soft, pitting, periorbital (most prominent in morning), dependent (legs/feet in daytime)
• Severe: ascites, pleural effusion, scrotal/vulval oedema, anasarca

Step 5: Hyperlipidaemia

• Hypoalbuminemia signals liver to increase lipoprotein synthesis
• Decreased catabolism of lipids
• Results in elevated total cholesterol, LDL, VLDL, triglycerides
• Lipiduria: Free fat, oval fat bodies, fatty casts in urine
• Maltese cross pattern on polarized light microscopy of urine

Step 6: Other Metabolic Consequences

• Loss of immunoglobulins (IgG) → susceptibility to infections
• Loss of clotting factors (antithrombin III, protein C and S) + increase in procoagulant factors → thrombosis
• Loss of thyroid binding globulin → altered thyroid function tests
• Loss of Vitamin D binding protein → hypocalcaemia
• Loss of transferrin → iron deficiency
• Loss of zinc

SECTION 4: CLINICAL FEATURES

Onset

• Often insidious; may follow upper respiratory tract infection
• First noticed as periorbital puffiness (morning), which parents may mistake for allergy
• Parents note swollen eyes, swelling of feet/legs, decreased urine output

History

• Periorbital oedema (earliest and most noticed sign)
• Generalized swelling (face, legs, abdomen)
• Decreased or frothy urine output (frothy urine = proteinuria)
• Decreased appetite
• Diarrhea (gut wall oedema)
• History of recent infection (URTI, skin infection)

Physical Examination Findings

SECTION 5: INVESTIGATIONS

Urine Examination

Blood Tests

Renal Biopsy

• NOT required for first presentation in children 1-12 years (assumed MCD; treat with steroids first)
• Indicated when:
  • Age < 1 year or > 12 years
  • Steroid resistant (no remission after 4 weeks of full-dose steroids)
  • Steroid dependent or frequently relapsing
  • Persistent haematuria, hypertension, or low complement
  • Secondary cause suspected

• Light microscopy: Normal glomeruli ("minimal change")
• Immunofluorescence: Negative (no deposits)
• Electron microscopy: Effacement (fusion) of podocyte foot processes - hallmark

SECTION 6: MANAGEMENT

A. General Measures

• Normal protein intake (1-2 g/kg/day) - high protein diets worsen proteinuria
• Low sodium diet (< 2 g/day) - to reduce oedema
• Low saturated fat diet (for hyperlipidaemia)
• Adequate calories; normal fluid intake unless severe oedema

• Restrict activity during acute oedematous phase
• Bed rest in Fowler's/semi-recumbent position
• Elevate lower limbs to reduce dependent oedema

• Restrict fluids only if severe hyponatraemia (serum Na < 125 mEq/L) or severe oedema with respiratory distress
• Otherwise, no fluid restriction necessary

B. Medical Management

1. STEROIDS (First-line, Most Important Treatment)

• Prednisolone: 2 mg/kg/day (max 60 mg/day) orally in single morning dose for 4 weeks (full dose)
• Then 1.5 mg/kg alternate days for 4 weeks (tapering)
• Total: 12 weeks of steroid therapy (longer = lower relapse rate)

2. DIURETICS (for severe oedema)

• Furosemide (Lasix): 1-3 mg/kg/day; loop diuretic; promotes sodium and water excretion
• Add spironolactone (potassium-sparing) to prevent hypokalemia
• IV albumin (salt-poor albumin 20%): 1 g/kg over 4-6 hours → followed immediately by IV furosemide; used for severe symptomatic oedema, hypovolaemia, ascites, pleural effusion
• Caution: Diuretics can worsen hypovolaemia and precipitate AKI in underfilled patients

3. ANTIBIOTICS

• Prophylactic Phenoxymethylpenicillin (penicillin V) in children with frequent relapses (reduces infection-triggered relapses)
• Treat infections promptly - most common precipitant of relapse is infection

4. SECOND-LINE AGENTS (for frequent relapsers, steroid-dependent, steroid-resistant)

5. TREATMENT OF HYPERLIPIDAEMIA

• Dietary fat restriction
• Statins (HMG-CoA reductase inhibitors) if persistent or high risk

6. ANTICOAGULATION

• Consider if serum albumin < 20 g/L or membranous nephropathy → high thrombosis risk
• Aspirin or low molecular weight heparin

SECTION 7: COMPLICATIONS

A. Infections (Most Common and Dangerous Complication)

• Spontaneous bacterial peritonitis (SBP): Most feared; Streptococcus pneumoniae most common organism; presents with fever, abdominal pain, tenderness; treat with IV cefotaxime/ceftriaxone
• Cellulitis, urinary tract infections, septicaemia
• Varicella: Severe, life-threatening if child is on steroids (reduce/stop steroids; give acyclovir; give VZIG prophylaxis to contacts)
• Causes: Loss of immunoglobulins (IgG), complement proteins; steroid-induced immunosuppression; oedema (bacterial culture medium)

B. Thromboembolism

• Deep vein thrombosis, renal vein thrombosis, pulmonary embolism
• Cause: Loss of antithrombin III, protein C and S; increased platelet aggregability; haemoconcentration; immobility
• Renal vein thrombosis: sudden worsening of haematuria and flank pain; confirmed by Doppler/CT angiography

C. Hypovolaemia (Shock)

• Occurs when aggressive diuresis or diarrhoea/vomiting reduces intravascular volume
• Signs: Tachycardia, cold extremities, abdominal pain, reduced urine output
• Treatment: IV albumin + fluids

D. Acute Kidney Injury (AKI)

• From hypovolaemia, sepsis, or interstitial nephritis (NSAIDs)

E. Steroid Side Effects (Long-term)

• Cushing's syndrome (moon face, buffalo hump, striae)
• Growth retardation
• Osteoporosis → fractures
• Hypertension
• Diabetes mellitus (steroid-induced)
• Cataracts, glaucoma
• Susceptibility to infection

F. Nutritional Problems

• Protein malnutrition due to urinary losses + dietary restriction
• Vitamin D deficiency → rickets, hypocalcaemia, tetany
• Iron deficiency anaemia

G. Psychosocial Impact

• Altered body image (oedema, Cushingoid appearance)
• School absenteeism
• Family stress and anxiety

SECTION 8: NEPHROTIC vs NEPHRITIC SYNDROME (Comparison - High-Yield)

SECTION 9: NURSING MANAGEMENT

Nursing Assessment

1. Daily weight (most sensitive indicator of fluid status; > 0.5 kg/day = fluid retention)
2. Abdominal girth measurement (for ascites monitoring)
3. Blood pressure (4-hourly)
4. Urine output (hourly in acute phase; target > 1 ml/kg/hr)
5. Urinalysis daily: protein, specific gravity, albumin
6. Skin assessment: Oedematous skin is fragile; check for pressure areas, breakdown, infection
7. Signs of infection: Fever, abdominal pain (peritonitis), respiratory distress
8. Signs of hypovolaemia: Tachycardia, cold extremities, abdominal pain, dizziness
9. Electrolytes, albumin, CBC - review results daily
10. Growth and development assessment

Nursing Diagnoses

Nursing Interventions

• Low sodium, low fat diet as prescribed
• Elevate lower limbs when in bed; elevate scrotum with support
• Position change every 2 hours
• Administer diuretics as prescribed; monitor response
• Administer IV albumin infusion as prescribed (run slowly; monitor for overload)

• Strict hand hygiene before and after care
• Isolate from infectious patients
• Avoid live vaccines while on high-dose steroids

• Provide favourite foods within dietary restrictions
• Calcium and Vitamin D supplements as prescribed
• Weigh and record dietary intake; involve dietitian

• Administer prednisolone with food (reduces gastric irritation)
• Give in morning (mimics cortisol diurnal rhythm; reduces sleep disturbance)
• Teach parents NOT to stop steroids abruptly (risk of adrenal crisis)
• Teach urine testing for protein (dipstick) at home - twice weekly
• Teach to seek help immediately for: fever, abdominal pain, marked increase in swelling, blood in urine, decreased urine output

• Restrict strenuous activity during acute oedematous phase
• Encourage gentle play within bed; provide age-appropriate toys
• Resume normal activity gradually as oedema resolves
• Encourage school attendance during remission

• Reassure child and family: MCD has good prognosis in children
• Encourage parents to express fears and ask questions
• Address body image concerns (oedema, cushingoid features on steroids)
• Connect with support groups
• Ensure continuity of education

SECTION 10: DISCHARGE PLANNING AND FOLLOW-UP

• Oedema resolved or significantly reduced
• On oral prednisolone (stable dose)
• Parents competent in urine dipstick testing
• Child tolerating diet and medications well

1. Urine dipstick protein testing at home - twice weekly; report 2+ or more for 3 consecutive days
2. Daily weight at home; report > 0.5 kg/day gain
3. Medication: Do not miss steroid doses; do not stop abruptly
4. Low sodium diet at home - avoid chips, pickles, processed foods

6. Avoid contact with chickenpox cases (notify school)
7. Follow-up appointments: Weekly initially, then monthly
8. Immunization: Pneumococcal vaccine, influenza vaccine; avoid live vaccines while on high-dose steroids
9. School: Can attend school during remission; inform teacher about condition

CONCLUSION

Exam tip for 50 marks: Structure your answer as: Introduction + Definition (4 hallmarks with the chain) + Classification with causes + Pathophysiology (step-by-step chain) + Clinical features + Investigations table + Medical management (steroid protocol + response definitions are highest-yield) + Complications (peritonitis, thrombosis, hypovolaemia) + Nephrotic vs Nephritic comparison table + Full nursing care plan + Discharge teaching. The pathophysiology chain and the nephrotic vs nephritic table are the most frequently tested components.

TETRALOGY OF FALLOT (TOF)

Complete 50-Mark Answer | Child Health Nursing (INC Pattern)

INTRODUCTION

SECTION 1: THE FOUR DEFECTS (Tetralogy) - Most Important Section

1. Ventricular Septal Defect (VSD)

• Large, perimembranous, pressure non-restrictive VSD
• Located high in the interventricular septum (subaortic/malalignment type)
• Allows mixing of oxygenated and deoxygenated blood between ventricles

2. Pulmonary Stenosis (Right Ventricular Outflow Tract Obstruction - RVOTO)

• Most important defect - determines severity of cyanosis
• Obstruction can be at multiple levels:
  • Infundibular (subvalvular): Most common; muscular obstruction below pulmonary valve
  • Valvular: Thickened, bicuspid pulmonary valve
  • Supravalvular/pulmonary artery: Hypoplastic main or branch pulmonary arteries
• Spectrum: Mild pulmonary stenosis → Pulmonary atresia (TOF/PA) - most severe form

3. Overriding Aorta

• The aortic root is enlarged and sits astride (overrides) the VSD
• Positioned over both ventricles (not exclusively over LV as normal)
• Degree of override varies (25-100%); if > 50% override → some classify as Double Outlet RV

4. Right Ventricular Hypertrophy (RVH)

• Secondary consequence of pulmonary stenosis (increased RV afterload)
• RV wall hypertrophies progressively
• At birth, RV and LV pressures equalize; RV pressure = systemic pressure
• RVH is progressive and worsens the obstruction over time

• Pulmonary stenosis (RVOTO)
• Right ventricular hypertrophy
• Overriding aorta
• VSD

SECTION 2: PATHOPHYSIOLOGY

Step-by-Step Haemodynamic Flow

1. Pulmonary stenosis creates resistance to pulmonary blood flow
2. RV pressure rises to equal or exceed LV pressure
3. Deoxygenated blood from RV finds the path of least resistance → through the VSD into the overriding aorta (right-to-left shunt)
4. Deoxygenated (blue) blood mixes with oxygenated blood in aorta → systemic cyanosis
5. The greater the RVOTO, the larger the R-to-L shunt → more cyanosis
6. Less blood reaches the lungs → reduced pulmonary blood flow
7. Chronic hypoxia → secondary polycythaemia (compensatory increase in RBC mass to carry more oxygen)
8. Polycythaemia → increased blood viscosity → risk of thrombosis and stroke

SECTION 3: CLINICAL FEATURES

A. CYANOSIS

• Central cyanosis - present in lips, tongue, mucous membranes, nail beds
• Appears at birth (if severe RVOTO) or during first weeks/months of life
• Worsens with activity, crying, feeding
• Progressive - worsens as infundibular stenosis increases with age

B. CLUBBING OF FINGERS AND TOES

• Develops over months to years in response to chronic hypoxia
• Early: Loss of angle between nail and nail bed (Lovibond angle)
• Late: Drumstick/watch-glass nail; soft tissue swelling at finger tips
• Also toes: "Drumstick toes"

C. HYPERCYANOTIC EPISODES ("TET SPELLS") - High-Priority Section

• Sudden episodes of intense cyanosis with hyperpnoea
• Age of peak occurrence: 2 months - 2 years
• Time of occurrence: Most commonly in the morning after waking up; also after feeding, crying, defecation, or exercise

1. Infundibular muscle spasm (triggered by sympathetic stimulation from crying, feeding, exertion)
2. → Sudden increase in RVOTO → drastic fall in pulmonary blood flow
3. → Massive increase in R-to-L shunt → profound drop in oxygen saturation
4. → Hypoxia → ↑ respiratory rate (hyperpnoea) → falls in PaCO₂
5. → Metabolic acidosis → further stimulation of respiratory center
6. → More hyperpnoea → worsens the cycle

• Sudden onset intense cyanosis
• Deep, rapid breathing (hyperpnoea - NOT respiratory distress)
• Loss of consciousness (if prolonged)
• Convulsions (if severe hypoxia)
• Disappearance or softening of the murmur during spell (less blood crossing the RVOT)

D. SQUATTING POSTURE (Pathognomonic of TOF)

• Older children (toddlers and above) instinctively squat after exercise
• Mechanism of squatting:
  • Squatting increases systemic vascular resistance (SVR) by kinking femoral arteries
  • Increased SVR → reduces R-to-L shunt (blood diverted to lungs)
  • Also traps deoxygenated blood in lower extremities
  • Net effect: Increased pulmonary blood flow → improved oxygenation

E. GROWTH AND DEVELOPMENT

• Poor weight gain and growth retardation (chronic hypoxia, poor feeding, increased metabolic demands)
• Fatigue on exertion; limits physical activity
• Developmental delays in severe untreated cases

F. POLYCYTHAEMIA

• Compensatory increase in RBC and haematocrit due to chronic hypoxia
• Haematocrit may exceed 60-70% in severe untreated cases
• Complications of polycythaemia:
  • Hyperviscosity → sluggish flow → thrombosis
  • Cerebral venous thrombosis (stroke-like episodes)
  • Brain abscess (R-to-L shunt bypasses pulmonary filter; bacteria enter systemic circulation)

G. MURMUR

• Harsh systolic ejection murmur at left upper sternal border (pulmonary stenosis murmur - ejection type)
• Not the VSD murmur (VSD is non-restrictive so no significant pressure gradient across it)
• Louder murmur = less severe TOF (more blood crossing RVOT = more PS turbulence)
• Softer murmur = more severe TOF (during tet spell, murmur may disappear)

H. OTHER SIGNS

• Parasternal heave (RVH)
• Single or loud S2 (diminished/absent pulmonary component)
• No cardiac failure in childhood (R-to-L shunt unloads RV into aorta)
• Absent congestive heart failure - distinguishes TOF from acyanotic CHD

SECTION 4: DIAGNOSIS / INVESTIGATIONS

A. Chest X-Ray (CXR)

• "Boot-shaped heart" (Coeur en Sabot) - pathognomonic appearance
  • Upturned cardiac apex (RVH pushes apex upward and laterally)
  • Concave (absent) main pulmonary artery segment (hypoplastic PA)
  • Normal or small cardiac size (no cardiomegaly - unlike left-to-right shunts)
• Decreased pulmonary vascular markings (oligaemic lung fields)
• Right aortic arch in 25% of cases

B. ECG (Electrocardiogram)

• Right axis deviation (RAD)
• Right ventricular hypertrophy (RVH): Tall R in V1, deep S in V5-V6; R > S in V1
• Right bundle branch block (RBBB) - often post-repair

C. Echocardiography (2D Echo + Doppler) - Gold Standard

• Defines all four components of TOF
• Anterior malalignment VSD + overriding aorta
• Infundibular/valvular/supravalvular PS and its severity (peak gradient)
• RV hypertrophy
• Pulmonary artery anatomy (main + branches)
• Coronary artery anatomy (critical pre-operative)
• Colour flow Doppler: Right-to-left shunt through VSD

D. Blood Tests

• CBC: Polycythaemia; elevated haematocrit (PCV > 55%); elevated haemoglobin
• Coagulation: Impaired (polycythaemia causes relative factor deficiency)
• ABG (Arterial Blood Gas): Low PaO₂; low oxygen saturation; may show metabolic acidosis during spells
• Iron studies: Iron deficiency anaemia worsens cyanosis (even mildly anaemic polycythaemic child has less oxygen carrying capacity)

E. Cardiac Catheterization

• Not routinely required (echo usually sufficient)
• Used pre-operatively when PA anatomy complex, coronary anomaly suspected, or prior to redo surgery

F. CT/MRI Angiography

• For complex pulmonary artery anatomy, aortopulmonary collaterals, and pre-operative planning

SECTION 5: MANAGEMENT

A. MEDICAL MANAGEMENT (Pre-surgical / Conservative)

1. Management of Tet Spell (Emergency - Most Important)

• Pick up child; hold in knee-chest position (simulates squatting)
• Reassure child and parents; reduce crying/agitation

• Flex knees to chest (foetal position)
• Increases SVR → reduces R-to-L shunt → more blood to lungs
• Can be done immediately by nurse/parent

• Give 100% oxygen by face mask
• Reduces hypoxia; reduces pulmonary vascular resistance
• Note: Oxygen alone rarely reverses a severe spell

• 0.1-0.2 mg/kg SC/IM/slow IV
• Relaxes infundibular muscle spasm (relieves RVOTO)
• Suppresses the hyperpnoeic response
• Drug of choice for tet spell

• Normal saline 10-20 ml/kg IV
• Increases preload; increases pulmonary blood flow
• Also helps if dehydrated (dehydration worsens spells)

• 1-2 mEq/kg IV for metabolic acidosis
• Corrects acidosis that stimulates the respiratory center

• 0.1-0.2 mg/kg slow IV
• Reduces HR; reduces infundibular muscle contractility (reduces RVOTO)
• Slows the heart → allows more filling time → more blood to lungs

• 0.02 mg/kg IV (or methoxamine)
• Increases SVR rapidly → diverts blood to lungs
• Used in refractory spells in ICU setting

2. Propranolol - Long-term Prophylaxis

• Oral propranolol 0.5-1.5 mg/kg/day in 3-4 divided doses
• Prevents recurrent tet spells by:
  • Reducing infundibular muscle hyperreactivity
  • Slowing heart rate
• Used as bridge to surgery if surgery delayed

3. Prevention of Complications

• Iron supplementation: Prevent iron deficiency (worsens cyanosis and increases stroke risk)
• Hydration: Avoid dehydration (increases blood viscosity, risk of stroke)
• Dental hygiene + SBE prophylaxis: Amoxicillin before dental procedures (prevents bacterial endocarditis)
• Phlebotomy (venesection): Rarely needed; only if haematocrit > 65% with symptoms (headache, visual changes) - remove 5-10 ml/kg blood and replace with saline

B. SURGICAL MANAGEMENT

1. Palliative Surgery (Temporary - Bridge to Complete Repair)

• Creates an anastomosis between subclavian artery and pulmonary artery
• Classic BTT (1944 - first cardiac surgery ever performed): Direct subclavian artery to PA
• Modified BTT (MBTT) - now standard: Gore-Tex synthetic tube graft between subclavian artery and ipsilateral PA
• Effect: Increases pulmonary blood flow → improves oxygenation → allows pulmonary arteries to grow
• Indication: Very small pulmonary arteries, complex anatomy, very small baby (< 3-4 kg), or when complete repair carries high risk

• Waterston shunt (ascending aorta to right PA)
• Potts shunt (descending aorta to left PA)
• Both largely abandoned due to complications

2. Complete (Total) Intracardiac Repair - Definitive Treatment

• Trend toward earlier repair; some centers repair as early as neonatal period if severely symptomatic
• Most do elective repair at 3-6 months before tet spells begin

1. VSD closure with Dacron/pericardial patch
2. Relief of RVOTO:
   • Resection of infundibular muscle
   • Pulmonary valvotomy (if valvular PS)
   • Transannular patch (TAP) - if pulmonary annulus too small; widened with patch → causes pulmonary regurgitation (long-term issue)
3. Repair/reconstruction of main and branch pulmonary arteries if hypoplastic
4. If anomalous coronary crosses RVOT → RV-to-PA conduit used instead of direct repair

• Pulmonary regurgitation (PR): Most significant long-term problem after TAP repair; causes progressive RV dilatation and dysfunction → may require pulmonary valve replacement later
• Residual RVOTO
• Arrhythmias: RBBB (universal); ventricular tachycardia (risk of sudden death)
• Residual VSD
• Aortic root dilatation

SECTION 6: CLASSIFICATION OF CONGENITAL HEART DISEASE (Context for TOF)

Acyanotic CHD (Left-to-Right Shunts) - No cyanosis initially

Cyanotic CHD (Right-to-Left Shunts) - Cyanosis present

• TOF
• TGA
• Tricuspid atresia
• TAPVR
• Truncus arteriosus

SECTION 7: NURSING MANAGEMENT

Pre-operative Nursing Care

Assessment

• Continuous cardiorespiratory monitoring (HR, RR, SpO₂)
• Assess degree of cyanosis: lips, tongue, nail beds, mucous membranes
• Monitor for tet spells (sudden increase in cyanosis, hyperpnoea, loss of consciousness)
• Daily weight and growth monitoring
• Assess feeding tolerance (cyanosis worsens during feeding)
• Neurological assessment (risk of stroke from polycythaemia)
• Observe for clubbing, squatting behavior

Nursing Diagnoses and Interventions

Feeding the Child with TOF

• Feed in upright or semi-upright position (reduces effort)
• Small, frequent feeds (every 2-3 hours rather than large feeds)
• Limit feeding time to 20-30 minutes (prolonged feeding is exhausting)
• Gavage/nasogastric feeding if SpO₂ drops during oral feeding
• High calorie formula or breast milk fortification if growth faltering
• Burp frequently during feeds

Prevention of Tet Spells

• Avoid prolonged crying (respond promptly; comfort child)
• Avoid constipation (straining triggers spells); ensure adequate hydration and fiber
• Maintain comfortable room temperature (cold stress triggers spells)
• Handle gently; minimize painful procedures
• Cluster care (group all interventions to allow rest periods)
• Position: Avoid hip extension; flexed position preferred

Peri-operative Nursing Care

• Complete pre-op assessment (cardiac catheterization review, echo review, blood group/crossmatch)
• Insert IV access; pre-op medications
• Educate parents about surgical procedure and ICU stay
• Ensure preoperative antibiotics (SBE prophylaxis)
• NPO (nil per os) as per surgical protocol

• Continuous monitoring: HR, BP, CVP, left atrial pressure, SpO₂, temperature
• Mechanical ventilation management (weaning according to protocol)
• Pain management (morphine infusion initially; then oral paracetamol/NSAIDs)
• Chest drain care: Monitor output, patency; record drainage
• Watch for complications:
  • Low cardiac output (cool periphery, oliguria, hypotension)
  • Pulmonary regurgitation (if transannular patch used) - volume load on RV
  • Arrhythmias: RBBB (universal post-repair); heart block; VT
  • Pneumothorax, haemothorax
  • Junctional ectopic tachycardia (JET) - common in first 24-48 hours
  • Residual VSD or RVOTO
• Fluid balance: Careful fluid management (cardiac surgery patients prone to fluid overload)
• Gradual advancement of feeds when extubated

Discharge Teaching

1. Explain medications: Digoxin (if prescribed), diuretics, prophylactic antibiotics
2. Infective Endocarditis prophylaxis: Amoxicillin before dental/surgical procedures
3. Wound care: Keep sternal wound clean and dry; signs of infection
4. Activity: Gradual return to normal activity; no contact sports for 6 weeks
5. Follow-up: Echo at 1 month, 6 months, then annually (monitor for PR, RVOTO)
6. Signs of deterioration: Increased cyanosis, tet spells, squatting, poor weight gain → seek care immediately
7. Iron supplementation (if prescribed)
8. Dental hygiene importance (prevention of bacteraemia)
9. School: Can attend school when recovered; inform teacher about condition

SECTION 8: PROGNOSIS

• Without surgery: 50% die by age 3 years; 70% by 10 years (from tet spells, brain abscess, stroke, infective endocarditis)
• With complete repair: > 90% long-term survival; most lead normal lives
• Long-term issues: Pulmonary regurgitation (40-60% need pulmonary valve replacement later); arrhythmias; residual RVOTO
• Survival into adulthood is standard with appropriate surgical management

CONCLUSION

Exam tip for 50 marks: Key sections the examiner expects: Introduction + 4 defects (PROV) with clear explanation + Pathophysiology (R-to-L shunt chain) + Clinical features (cyanosis, clubbing, tet spell mechanism, squatting mechanism - these two are highest scoring) + CXR findings (boot-shaped heart) + ECG + Echo + Management of tet spell step-by-step (this section alone can fetch 10-15 marks) + Surgical management (BTT shunt vs complete repair) + Full nursing care plan + Post-operative care. Diagrams of heart anatomy in the exam will earn bonus marks.

MENINGITIS IN CHILDREN - NURSING MANAGEMENT

Complete 50-Mark Answer | Child Health Nursing (INC Pattern)

INTRODUCTION

SECTION 1: CLASSIFICATION / TYPES

By Causative Agent:

By Age Group - Common Organisms:

SECTION 2: AETIOLOGY AND RISK FACTORS

Risk Factors for Meningitis:

1. Age < 5 years and especially < 1 year (immature blood-brain barrier, immature immunity)
2. Unimmunized children (Hib vaccine, PCV, meningococcal vaccine)
3. Overcrowded living conditions
4. Close contacts of meningococcal cases
5. Preceding URTI or otitis media (sinusitis, mastoiditis)
6. Head trauma, neurosurgery (direct inoculation)
7. CSF shunt, cochlear implant
8. Immunocompromised state (HIV, malnutrition, sickle cell disease, asplenia)
9. Complement deficiency (increased risk of meningococcal disease)

Routes of Infection:

• Haematogenous (most common): Bacteria colonize nasopharynx → enter bloodstream → seed meninges
• Direct spread: Otitis media, sinusitis, mastoiditis, orbital cellulitis
• Direct inoculation: Head trauma, neurosurgery, lumbar puncture (rare)

SECTION 3: PATHOPHYSIOLOGY

Step-by-Step Mechanism:

1. Pathogen enters subarachnoid space (via blood or direct spread)
2. Bacteria multiply in CSF (poor immune defenses - low complement and immunoglobulins in CSF)
3. Bacterial cell wall components (LPS, teichoic acid) trigger inflammatory cascade
4. Release of cytokines: TNF-α, IL-1, IL-6, IL-8
5. → Increased blood-brain barrier (BBB) permeability → vasogenic oedema
6. → Neutrophil infiltration into CSF → CSF becomes turbid/purulent
7. → Cerebral oedema (vasogenic + cytotoxic + interstitial) → raised ICP
8. → Impaired cerebral autoregulation → cerebral ischaemia
9. → Vasculitis of cerebral blood vessels → thrombosis → infarction, seizures
10. → Hydrocephalus (exudate obstructs CSF flow) → further raised ICP
11. → Herniation (if untreated) → death

SECTION 4: CLINICAL FEATURES

A. Classical Triad (All Ages)

1. Fever (high grade, sudden onset)
2. Headache (severe, generalised, "worst headache of life")
3. Neck stiffness (nuchal rigidity)

B. Meningeal Signs (Signs of Meningeal Irritation)

• Resistance to passive forward flexion of the neck
• Patient cannot touch chin to chest
• Pathognomonic sign of meningeal irritation
• May be absent in very young infants (< 3 months) and immunocompromised

• Patient lies supine; hip flexed to 90°
• Attempt to passively extend the knee beyond 135° causes pain and resistance (hamstring spasm)
• Positive = meningeal irritation

• Patient lies supine
• Passive flexion of the neck causes spontaneous flexion of both hips and knees
• Positive = meningeal irritation
• Also: Brudzinski's contralateral leg sign - flexion of one hip and knee causes same movement in opposite leg

C. Age-Specific Features

• Classical signs often absent (no neck stiffness, no Kernig's/Brudzinski's)
• Non-specific signs:
  • Bulging fontanelle (raised ICP)
  • High-pitched cry (cerebral irritation)
  • Poor feeding/refusal to feed
  • Lethargy, irritability
  • Temperature instability (fever OR hypothermia)
  • Apnoea
  • Seizures
  • Jitteriness

• Fever + irritability + bulging fontanelle
• Neck stiffness begins to appear
• Seizures common

• Classical triad: Fever + Headache + Neck stiffness
• Photophobia (sensitivity to light)
• Phonophobia (sensitivity to sound)
• Vomiting (projectile, from raised ICP)
• Altered level of consciousness (drowsiness → stupor → coma)
• Seizures (15-40% of cases)

D. Additional Features by Organism

• Petechial rash - begins as maculopapular rash → rapidly becomes petechial/purpuric (non-blanching)
• Found on trunk, lower extremities, mucous membranes, conjunctiva
• Indicates meningococcaemia (septicaemia) - most dangerous form
• Waterhouse-Friderichsen syndrome: Bilateral adrenal haemorrhage; DIC; septic shock; extremely high mortality
• Glass test: Press glass on petechiae → they do NOT blanch (unlike viral rash)

• Severe; may complicate otitis media, sinusitis, pneumonia
• Higher risk of complications (hearing loss, cerebral abscess)

• Subacute onset over days to weeks
• Low-grade fever, headache, vomiting, behavioural changes
• Cranial nerve palsies (III, IV, VI, VII)
• Choroidal tubercles on fundoscopy

E. Signs of Raised ICP

• Deteriorating consciousness (Glasgow Coma Scale falling)
• Papilloedema (on fundoscopy)
• Dilated, poorly reactive pupils
• Sixth nerve palsy (lateral rectus weakness → squint)
• Decerebrate/decorticate posturing
• Cushing's Triad: Bradycardia + hypertension + irregular respirations (late, pre-terminal sign)
• Herniation: Uncal herniation → ipsilateral fixed dilated pupil; central herniation → brainstem compression → death

SECTION 5: DIAGNOSIS / INVESTIGATIONS

A. Lumbar Puncture (LP) - Gold Standard Diagnosis

• Do LP immediately if no contraindications
• Do NOT delay antibiotics for LP if contraindications present - start antibiotics first, then LP when safe

1. Papilloedema (raised ICP)
2. Focal neurological signs (suggests focal lesion)
3. GCS ≤ 8 or rapidly deteriorating consciousness
4. Coagulopathy / thrombocytopenia
5. Skin infection at LP site
6. Haemodynamic instability

B. CSF Analysis - Most Important Table

C. Blood Investigations

• Blood culture (2 sets before antibiotics) - positive in 50-80% bacterial meningitis
• CBC: Elevated WBC, neutrophilia (bacterial); lymphocytosis (viral)
• CRP, Procalcitonin: Markedly elevated in bacterial; less in viral
• Serum glucose: For CSF:blood glucose ratio
• Electrolytes: Hyponatremia (SIADH common complication)
• Serum sodium: Low (water retention → cerebral oedema worsens)
• Coagulation profile: DIC screening (PT, APTT, platelet, fibrinogen)
• Blood urea, creatinine

D. Other Investigations

• CT Head: Before LP if signs of raised ICP; rule out space-occupying lesion
• MRI Brain: For complications (infarction, abscess, subdural empyema)
• Chest X-ray: For TB (hilar lymphadenopathy, miliary TB)
• Mantoux test / IGRA: For TB meningitis
• PCR on CSF: For viral (HSV, enteroviruses), meningococcus, pneumococcus - highly sensitive
• Throat swab, nasopharyngeal culture: For meningococcus

SECTION 6: MANAGEMENT

A. EMERGENCY MANAGEMENT - Bacterial Meningitis (TIME-CRITICAL)

• Airway: Secure airway; intubate if GCS ≤ 8 or airway compromised
• Breathing: Supplemental oxygen; mechanical ventilation if needed
• Circulation: IV access × 2; fluid resuscitation for shock; blood cultures NOW

• 2 blood cultures before antibiotics (does NOT delay by more than 5-10 minutes)

B. ANTIBIOTIC TREATMENT

• N. meningitidis: Penicillin G (if sensitive) OR Ceftriaxone; 7 days
• S. pneumoniae: Penicillin G (if sensitive); Ceftriaxone + Vancomycin (if resistant); 10-14 days
• Hib: Ceftriaxone; 7-14 days
• GBS/Listeria (neonates): Ampicillin + Gentamicin; 14-21 days

C. DEXAMETHASONE (Adjunctive Corticosteroid)

• Dose: 0.15 mg/kg IV every 6 hours for 4 days
• Timing: Give 20 minutes BEFORE (or at least concurrent with) first antibiotic dose
• Mechanism: Reduces inflammatory cytokine cascade → decreases cerebral oedema, vasculitis, BBB damage
• Proven benefit: Reduces hearing loss and neurological sequelae in Hib meningitis and pneumococcal meningitis
• Not beneficial if given after antibiotics started

D. MANAGEMENT OF RAISED ICP

1. Head elevation: 30° head-up position (reduces venous congestion; improves cerebral venous drainage)
2. Avoid neck flexion: Maintain head in neutral position
3. IV Mannitol: 0.25-1 g/kg as osmotic diuretic; reduces cerebral oedema; given over 30-60 minutes
4. Hypertonic saline (3%): Alternative to mannitol; 3-5 ml/kg bolus; raises serum osmolarity
5. Restrict fluids: Once SIADH confirmed; restrict to 2/3 maintenance
6. Intubation + hyperventilation: To lower PaCO₂ to 30-35 mmHg → vasoconstriction → reduces ICP (temporary measure)
7. Avoid hypotension: Maintains cerebral perfusion pressure

E. MANAGEMENT OF SEIZURES

• IV Phenobarbitone (first-line in neonates): 20 mg/kg IV loading dose
• IV Diazepam or Lorazepam (acute seizures): 0.1-0.2 mg/kg IV
• IV Phenytoin (second-line): 15-20 mg/kg IV loading
• Continuous seizure monitoring; EEG if subclinical seizures suspected

F. MANAGEMENT OF SIADH (Syndrome of Inappropriate ADH)

• Complicates 30-50% of bacterial meningitis
• Hyponatraemia (serum Na < 135 mEq/L)
• Risk: Worsens cerebral oedema (water moves into brain cells)
• Management:
  • Fluid restriction: 2/3 maintenance (60-70 ml/kg/day)
  • Hypertonic saline (3%) if severe hyponatraemia (Na < 120 or symptomatic)
  • Monitor serum sodium every 6-12 hours; correct slowly (not faster than 0.5 mEq/L/hr to avoid central pontine myelinolysis)

G. CHEMOPROPHYLAXIS FOR CONTACTS

• All close contacts (household members, those with contact with oral secretions)
• Rifampicin: 10 mg/kg (max 600 mg) every 12 hours for 2 days (oral)
• Alternative single-dose: Ceftriaxone 125 mg IM (children < 15 years) OR Ciprofloxacin 500 mg oral (adults)
• Azithromycin 500 mg single dose in pregnancy

• Rifampicin 20 mg/kg (max 600 mg) once daily for 4 days
• For household contacts with unimmunized children < 4 years

SECTION 7: COMPLICATIONS

A. Acute Complications

B. Long-term Sequelae (30% of survivors)

SECTION 8: NURSING MANAGEMENT

Nursing Assessment

1. Vital signs: Temperature, pulse, BP, respiratory rate every 1-2 hours (watch for Cushing's triad)
2. Neurological monitoring: GCS every 1-2 hours; pupil size, equality, and reactivity
3. Fontanelle assessment (infants): Bulging = raised ICP; sunken = dehydration
4. Seizure observation: Document type, duration, frequency; post-ictal state
5. Neck stiffness and meningeal signs: Reassess regularly
6. Rash monitoring: Check skin for petechiae or purpura; mark edges with pen and recheck hourly
7. Intake-output chart: Monitor for oliguria (septic shock) or excess output
8. Pain assessment: Headache severity using age-appropriate scale
9. Hearing assessment: Audiometry at discharge (especially pneumococcal/Hib)

Nursing Diagnoses and Interventions

Isolation Precautions

Positioning and Environment

1. Head of bed elevated 30° (reduces ICP by improving venous drainage)
2. Head in neutral alignment (avoid neck flexion or rotation - impairs jugular venous return)
3. Quiet, dimly lit room (reduces sensory stimulation; helps photophobia and headache)
4. Avoid clustering of painful procedures
5. Minimal disturbance during ICP monitoring
6. No tight clothing around neck

Medication Administration

1. Administer antibiotics on time (delays worsen outcome; "time is brain")
2. Give dexamethasone 20 minutes before antibiotics (if prescribed)
3. Ensure IV access remains patent (antibiotics must be given IV for meningitis)
4. Monitor for antibiotic reactions
5. Mannitol: Give rapidly over 30-60 min; monitor urine output
6. Phenobarbitone/Phenytoin: IV administration; monitor for respiratory depression, hypotension

Family/Parent Education

1. Explain meningitis and its treatment plan
2. Notify family about chemoprophylaxis (rifampicin for household contacts)
3. Teach warning signs of relapse
4. Arrange audiological testing at discharge and follow-up
5. Developmental follow-up after discharge
6. Immunization: Ensure PCV, Hib, Meningococcal vaccines are up to date
7. Report contacts to public health authority (meningococcal disease is notifiable)

SECTION 9: COMPARISON - BACTERIAL vs VIRAL vs TB MENINGITIS

SECTION 10: PREVENTION

1. Immunization:
   • Hib vaccine (in Pentavalent): Dramatically reduced Hib meningitis
   • PCV (Pneumococcal Conjugate Vaccine): Reduces Pneumococcal meningitis
   • Meningococcal vaccine: For high-risk groups, travellers to endemic areas
   • BCG vaccine: Protects against TB meningitis in children
   • MMR vaccine: Prevents mumps meningitis
2. Chemoprophylaxis: Rifampicin for contacts of meningococcal/Hib cases
3. Environmental measures:
   • Reduce overcrowding
   • Adequate ventilation
   • Good nutrition and general immunity
4. Notification: Bacterial meningitis (especially meningococcal) is a notifiable disease in India - must be reported to public health authorities within 24 hours
