I now have enough core content from Park's. Let me now provide all 25 answers in a detailed, exam-ready, memorisable format based on my knowledge and what I've gathered from the textbook.
π University Exam Theory Answers β All 25 Topics
(MCH / Community Health / Obstetrics & Paediatrics)
1. School Health Services
Definition: Organized services provided to school-age children to protect and promote their health.
Essential Services (remember: S-I-M-D-C-M)
- Screening: General health, anaemia, nutrition, visual acuity, hearing, dental, skin, physical disabilities, learning disorders, behaviour problems
- Immunization: As per national schedule; fixed-day activity
- Micronutrient management: Weekly IFA tablets + Vitamin A in needy cases
- Deworming: Biannually (siblings also covered)
- Capacity building and monitoring
- Mid-day meal
Desirable - Health Promoting Schools:
- Counselling, yoga/physical education, peer health educators
- Adolescent health education, health clubs/cabinets, first aid rooms
Key: A doctor from PHC/CHC visits one school per week based on screening reports.
2. Perinatal Mortality Rate (PMR)
Definition: Deaths occurring in the perinatal period - from 28 weeks of gestation to the 7th day after birth (ICD-8). Includes late foetal deaths (stillbirths) + early neonatal deaths.
Formula (WHO - developing nations):
PMR = (Late foetal deaths β₯28 wks + Early neonatal deaths in 1st week) / Live births in same year Γ 1000
Formula (WHO - developed nations):
PMR = (Late foetal deaths + Early neonatal deaths) / (Live births + Late foetal deaths) Γ 1000
For International Comparisons:
Babies >1000 g birth weight used as denominator (equivalent to 28 weeks gestation)
Why PMR is preferred over NMR alone?
- It combines stillbirths + early neonatal deaths
- Same causes operate across both periods (anoxia, infection, prematurity)
- Better indicator of obstetric and perinatal care quality
3. Newborn Care
Goal: Reduce perinatal and neonatal mortality.
ABCDE of Immediate Newborn Care:
- Airway - clear, resuscitation if needed
- Breathing - assess, stimulate
- Cord - delayed clamping (reduces anaemia)
- Dry - immediate drying, prevent hypothermia
- Exclusive breastfeeding - early initiation within 1 hour
Key Steps (remember "Dr. Warm - B.C.A.T"):
- Dry immediately, rub to stimulate
- Warmth - skin-to-skin, head cover, delayed bathing
- Breastfeeding - exclusive, early
- Cord care - clean, delayed clamping
- Antibiotic eye drops, Vitamin K at birth
- Transfer to NBSU/SNCU if danger signs
Newborn care levels:
- NBCC (Newborn Care Corner) - in every delivery room (mandatory)
- NBSU (Newborn Stabilization Unit) - at all FRUs/CHCs (4-bed unit)
- SNCU (Special Newborn Care Unit) - facilities with >3000 deliveries/year (12 beds minimum)
4. Psychological Problems of Elderly

6. ICDS Scheme (Integrated Child Development Services)
Launched: 1975 | Target group: Children 0-6 yrs + pregnant/lactating mothers + adolescent girls
6 Services (remember: "SNI-HEN"):
- Supplementary nutrition
- Non-formal pre-school education
- Immunization
- Health checkup
- Education and health education to mothers
- Nutrition education + referral services
Delivery point: Anganwadi Centre (one per 1000 population)
Anganwadi Worker (AWW): Frontline worker; trained village woman
Objectives:
- Improve nutritional and health status of children 0-6 yrs
- Lay foundation for psychological, social and educational development
- Reduce mortality, morbidity, malnutrition
- Achieve effective co-ordination of policy and implementation between departments
7. Healthy School Environment
4 components: Physical, Social, Mental, Safety
Physical environment:
- Adequate classroom space, lighting, ventilation
- Safe drinking water, sanitation (separate toilets for boys/girls)
- Playground, clean surroundings
Social environment:
- Positive teacher-student relationships
- Anti-bullying, anti-discrimination policies
Mental/emotional environment:
- Stress-free learning environment
- Counselling services available
Safety:
- First aid facility
- Safe school building (no structural hazards)
- Safe transportation
Health-promoting school (WHO concept): A school that constantly strengthens its capacity as a healthy setting for living, learning, and working.
8. Infant Mortality Rate (IMR)
Formula:
IMR = Deaths of children <1 year of age in a year / Live births in same year Γ 1000
Two components:
- Neonatal mortality rate (NMR): Deaths in first 28 days
- Early NMR: 0-7 days
- Late NMR: 7-28 days
- Post-neonatal mortality rate (PNMR): 28 days to 1 year
Causes of neonatal death: Prematurity, birth asphyxia, infections (sepsis, tetanus)
Causes of post-neonatal death: Diarrhoea, ARI, malnutrition, vaccine-preventable diseases
Importance: IMR is the most sensitive indicator of health status of a community, level of living, and effectiveness of MCH services.
India IMR: Fell from 88 (1990) to 32 (2018) per 1000 live births.
9. Maternal Mortality (School Health Services in Q9 is a duplicate - answer is on Maternal Mortality)
Definition (WHO): Death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of site/duration, from causes related to or aggravated by the pregnancy - but NOT from accidental/incidental causes.
MMR Formula:
MMR = Deaths due to complications of pregnancy/childbirth/puerperium in 1 year / Live births in same year Γ 100,000
Types:
- Direct obstetric death: From obstetric complications (haemorrhage, eclampsia, sepsis, obstructed labour, unsafe abortion)
- Indirect obstetric death: From pre-existing disease aggravated by pregnancy (e.g., heart disease, anaemia)
- Late maternal death: >42 days but <1 year after termination
"3 Delays" model of maternal death:
- Delay in deciding to seek care
- Delay in reaching the facility
- Delay in receiving adequate care
India MMR: Declined significantly - target <70 per 100,000 (SDG).
10. Perinatal Mortality Rate
(Already covered in detail in Q2 above - same topic repeated in the list)
Quick Revision Points:
- Perinatal period: 28 weeks gestation β 7th day of life
- Includes: Stillbirths (β₯28 wks) + Early neonatal deaths (0-7 days)
- Best indicator of: Quality of obstetric care + perinatal services
- ICD-10 criterion: Birth weight β₯1000 g (= 28 weeks)
11. MCH Indicators (Maternal and Child Health)
Definition: Statistical measures used to assess the health of mothers and children in a community.
Key Indicators (remember "MCH = MAP"):
Maternal indicators:
- Maternal Mortality Ratio (MMR)
- Proportion of antenatal care coverage (ANC)
- Proportion of institutional deliveries
- Proportion of births attended by skilled birth attendants
- Contraceptive prevalence rate
Child health indicators:
- Infant Mortality Rate (IMR)
- Neonatal Mortality Rate (NMR)
- Under-5 Mortality Rate (U5MR)
- Perinatal Mortality Rate (PMR)
- Low Birth Weight rate (<2500 g)
- Malnutrition rates (stunting, wasting, underweight)
- Immunization coverage rates
Nutritional indicators:
- Proportion of exclusively breastfed infants
- Vitamin A supplementation coverage
12. Dietary Advice to Antenatal Mother
Extra calorie requirement: +350 kcal/day in pregnancy; +550 kcal/day in lactation
Key nutrients (remember "PICA-CF"):
- Protein: +23 g/day β tissue growth, fetal development (milk, eggs, pulses)
- Iron: 60 mg/day + folic acid 500 mcg/day (IFA tablets)
- Calcium: 1200 mg/day (milk, dairy, ragi)
- AVitamin A: Important for fetal development
- Calories: +350 kcal/day above normal
- Folate: 500 mcg/day; prevents neural tube defects
General advice:
- 5-6 small meals instead of 3 large ones
- Avoid raw/undercooked meat, alcohol, excess caffeine
- Adequate hydration (8-10 glasses water/day)
- If vegetarian: extra protein from pulses + Vitamin B12 supplementation
Weight gain: Normal weight woman should gain 11-13 kg during pregnancy.
13. Postpartum Haemorrhage (PPH)
Definition: Blood loss β₯500 mL after vaginal delivery, or β₯1000 mL after caesarean section within 24 hours (Primary PPH) or between 24 hours and 6 weeks (Secondary PPH).
"4 T's" causes:
| T | Cause | Frequency |
|---|
| Tone | Uterine atony | 70-80% |
| Trauma | Lacerations, rupture | 20% |
| Tissue | Retained placenta | common |
| Thrombin | Coagulation defects | rare |
Prevention (Active Management of 3rd Stage - AMTSL):
- Oxytocin 10 IU IM within 1 minute of delivery (drug of choice)
- Controlled cord traction (Brandt-Andrews method)
- Uterine massage after placenta delivery
Management:
- HAEMOSTATS mnemonic: Haemorrhage β Assess β Establish IV access β Massage uterus β Oxytocin β Stat (further drugs: ergometrine, misoprostol, carboprost) β Transfuse β Apply B-Lynch suture/balloon β Surgery (hysterectomy last resort)
14. Postpartum Care
Definition: Care given to mother (and baby) after delivery, covering 6 weeks (42 days) after birth - the puerperium.
Key areas (remember "BENEFITS"):
- Breastfeeding: Encourage exclusive breastfeeding
- Emocional support: Screen for postnatal depression
- Nutrition: Iron-folic acid supplementation continued for 3 months
- Examination: Check uterus involution, lochia, perineum, BP
- Family planning: Counsel on contraception
- Immunization: Baby's vaccination, mother's Td booster
- Training: Newborn care, danger signs recognition
- Screening: Anaemia, infection, thrombosis
Warning signs (refer immediately):
- Heavy bleeding, foul-smelling lochia
- High fever, breast abscess
- Severe headache, convulsions (eclampsia)
- Suicidal thoughts (puerperal psychosis)
Visits: At 24 hrs, 48 hrs, 7 days, 42 days postpartum.
15. Rooming-in
Definition: A practice where the newborn is kept in the same room with the mother (rather than in a separate nursery) throughout the hospital stay.
Benefits:
- For mother: Promotes bonding, increases breastfeeding confidence, reduces anxiety
- For baby: Promotes breastfeeding (on demand), reduces formula use, regulates infant temperature/glucose
- Infection control: Reduces nosocomial (hospital-acquired) infections in nursery
Key points:
- Baby kept within arm's reach (within 1 metre)
- 24-hour rooming-in preferred
- Encourages skin-to-skin contact (Kangaroo care)
- One of the "10 Steps to Successful Breastfeeding" (WHO/UNICEF)
- Essential criterion for Baby Friendly Hospital Initiative (BFHI)
16. Apgar Score
Assessed at 1 minute and 5 minutes after birth.
"APGAR" Mnemonic:
| Letter | Parameter | 0 | 1 | 2 |
|---|
| A | Appearance (skin colour) | Blue/pale all over | Body pink, extremities blue | Completely pink |
| P | Pulse (heart rate) | Absent | <100/min | β₯100/min |
| G | Grimace (reflex irritability) | No response | Grimace | Cry/cough/sneeze |
| A | Activity (muscle tone) | Limp | Some flexion | Active motion |
| R | Respiration | Absent | Weak/irregular | Strong cry |
Interpretation:
- 7-10: Normal (good condition)
- 4-6: Moderate depression (needs stimulation/oxygen)
- 0-3: Severe depression (needs immediate resuscitation)
Note: Apgar score at 5 minutes better predictor of neonatal outcome than 1-minute score.
17. Small for Gestational Age (SGA)
Definition: Birth weight below 10th percentile for gestational age (or <2 standard deviations below mean).
Differentiate:
- SGA = small relative to gestational age (may be term but small)
- LBW = birth weight <2500 g (regardless of gestation)
- IUGR = Intrauterine growth restriction (process causing SGA)
Types of IUGR:
- Symmetrical (Type I): Head + body both small; early insult (chromosomal, infections like TORCH); poor prognosis
- Asymmetrical (Type II): Head spared, body small (brain sparing); late insult (placental insufficiency, maternal malnutrition); better prognosis
Causes:
- Maternal: Malnutrition, smoking, hypertension, anaemia, drugs
- Fetal: Chromosomal abnormalities, TORCH infections, multiple pregnancy
- Placental: Insufficiency, infarction
Complications: Hypothermia, hypoglycaemia, polycythaemia, perinatal asphyxia, increased mortality
18. Intranatal Care
Definition: Care provided to the mother during labour and delivery (intrapartum period).
Goals: Safe delivery, prevent complications, immediate newborn care.
Key components (remember "CLEAN-R"):
- Clean delivery: Sterile gloves, clean surface, instruments
- Labour monitoring: Partograph (tracks labour progress)
- Emergency management: Manage complications - PPH, dystocia, eclampsia
- AMTSL: Active management of 3rd stage (oxytocin + controlled cord traction)
- Newborn: Immediate newborn care (ABCD - airway, breathing, cord, dry/warm)
- Referral: Timely referral if high-risk features
Partograph: WHO tool to monitor:
- Fetal heart rate (every 30 min)
- Cervical dilatation (alert/action line)
- Descent of presenting part
- Contractions, maternal vitals
Normal labour: Latent phase β€8 hrs; Active phase cervical dilatation β₯1 cm/hr
19. Kangaroo Mother Care (KMC)
Definition: A method of caring for preterm/LBW infants involving continuous skin-to-skin contact between baby and mother (or another caregiver), along with exclusive breastfeeding.
3 Components (K-S-E):
- Kangaroo position: Baby placed vertically on mother's chest, between breasts (skin-to-skin, 24 hrs/day as much as possible)
- Support for breastfeeding: Exclusive breastmilk/breast feeding
- Early discharge: With follow-up
Benefits (remember "WATCH-B"):
- Warmth: Maintains temperature (replaces incubator)
- Apnea: Reduces apneic episodes
- Thriving: Better weight gain
- Crying: Reduced crying
- Health: Lower infection rates, mortality
- Bonding/Breastfeeding: Promotes both
WHO recommends KMC for all babies β€2000 g starting immediately after birth if stable.
20. Juvenile Delinquency
Definition: Antisocial or criminal behaviour by persons below 18 years of age (legal definition). Also called "behaviour disorder of adolescence."
Types:
- Truancy, running away from home
- Theft, vandalism, violence
- Substance abuse
- Sexual offences
Causes (Bio-Psycho-Social model):
- Individual: Low IQ, hyperactivity, poor impulse control
- Family: Broken homes, neglect, abuse, parental criminality, poverty
- Social: Peer pressure, bad company, slum environment
- School: Academic failure, bullying, school dropout
Prevention:
- Primary: Counselling, family support, education, youth clubs, sports
- Secondary: Early identification, child guidance clinics
- Tertiary: Juvenile justice system, rehabilitation, vocational training
Child Guidance Clinics - key preventive tool; team = paediatrician + psychiatrist + social worker + psychologist.
21. Feeding of Normal Infant
Birth to 6 months: Exclusive breastfeeding (nothing else - not even water)
Breast milk advantages (remember "INDIA"):
- Immunity: IgA, lactoferrin, lysozyme
- Nutrition: Perfect balance; easily digestible
- Digestion: Whey proteins > casein (easier to digest)
- Intelligence: Better neuro-development
- Allergy protection: Reduces eczema, asthma
6 months onwards: Complementary feeding started (soft foods)
- Frequency: 2 times/day (6-8 months) β 3 times (9-11 months) β 3-4 times (12-23 months) + snacks
- Texture: Puree β mashed β family food progressively
Weaning foods:
- Rice/ragi kanji, mashed dal, banana, egg yolk
- Avoid honey (<1 year - botulism risk), whole cow's milk (<1 year)
Breastfeeding continued up to 2 years or beyond (WHO recommendation).
22. Essential Antenatal Care
Definition: Minimum package of care provided to all pregnant women to detect complications early and ensure safe delivery.
4 ANC visits (WHO minimum, India):
- 1st visit: <12 weeks (ideally at registration)
- 2nd visit: 14-26 weeks
- 3rd visit: 28-34 weeks
- 4th visit: 36 weeks onwards
"3 examinations" at each visit: BP, weight, urine (albumin + sugar)
Essential package (remember "TAN-B-IC"):
- Tetanus toxoid: 2 doses (TT1 at 16 wks; TT2 4 wks later)
- Anaemia detection + IFA tablets (60 mg iron + 500 mcg folic acid)
- Nutrition counselling
- Blood tests: Hb, blood group, Rh typing, VDRL, HIV, blood glucose
- Investigations: Ultrasound (anomaly scan at 18-20 wks)
- Counselling: Danger signs, birth preparedness, breastfeeding
High-risk pregnancy detection is a key goal.
23. IMNCI (Integrated Management of Neonatal and Childhood Illness)
Definition: A WHO/UNICEF strategy to reduce mortality from leading causes of death in children under 5 years through an integrated case management approach.
Illnesses covered (remember "MAPND"):
- Malaria
- Acute Respiratory Infection (pneumonia)
- Persistent diarrhoea
- Nutrition (malnutrition, anaemia)
- Disease - measles, ear infection
3 Components:
- Curative: Algorithm-based case management (classify β treat/refer)
- Preventive: Immunization, nutrition counselling
- Promotive: Growth monitoring, breastfeeding promotion
IMNCI Assessment approach:
- Check for danger signs first (can't drink, vomiting everything, convulsions, very sleepy)
- Then assess for main symptoms
- Then check for malnutrition/anaemia
- Then check immunization status
IMNCI added neonatal component (0-2 months) - called F-IMNCI (Facility-IMNCI) for sick young infants.
24. Baby Friendly Hospitals (BFHI)
Full name: Baby Friendly Hospital Initiative - launched by WHO and UNICEF in 1991.
Purpose: Encourage hospitals to support breastfeeding and mother-infant bonding.
"10 Steps to Successful Breastfeeding" (BFHI criteria):
(Steps 1-5 - Hospital policy/support):
- Written breastfeeding policy
- Train all staff
- Inform all pregnant women about benefits of breastfeeding
- Initiate breastfeeding within 1 hour of birth
- Show mothers how to breastfeed and maintain lactation
(Steps 6-10 - Practices):
6. Give no food/drink other than breast milk unless medically indicated
7. Practice rooming-in (24 hours)
8. Encourage breastfeeding on demand
9. Give no artificial teats or pacifiers
10. Foster establishment of breastfeeding support groups
Additional condition: Hospital must not receive free or low-cost breast milk substitutes.
25. Risk Approach
Definition: A method of identifying and targeting high-risk individuals or groups for special care/intervention, using risk factors as screening tools.
Levels of risk in MCH:
- Low risk: No risk factors
- High risk: One or more risk factors present (needs extra care)
- Very high risk: Multiple or severe risk factors (needs referral)
Risk factors in obstetrics (remember "AGED-PAST"):
- Age: <20 or >35 years
- Grand multipara: β₯5 deliveries
- Expectant height: <145 cm
- Delivery complications in past
- Previous caesarean/surgery
- Anaemia (Hb <7 g/dL)
- Stillbirth/neonatal death in past
- Twins/multiple pregnancy, prolonged infertility
Advantages:
- Concentrates resources where most needed
- Cost-effective
- Reduces maternal and child mortality
Disadvantages:
- Over-medicalisation of normal pregnancy
- May miss some high-risk cases without identifiable factors
- Creates anxiety in mothers labelled "high-risk"
Risk scoring systems: Hobel's score, Coopland's score used clinically.
Exam Tips:
- Questions on PMR, IMR, MMR always need the formula + definition + causes
- ICDS, IMNCI, BFHI - always mention the year launched + key components
- Apgar score - draw the table; always mention 1 and 5 minute assessment
- KMC - mention 3 components + WHO recommendation
- PPH - mention the 4 T's + AMTSL (oxytocin is drug of choice)
