Good morning, BSc Nursing students! Here is your complete practical exam revision guide covering all 9 procedures. Study carefully!

🩺 BSc Nursing Practical Exam Revision Guide

1. CONVERSION OF TEMPERATURE (Celsius ↔ Fahrenheit)

Formulas (must memorize):

Conversion	Formula
Celsius to Fahrenheit	°F = (°C × 9/5) + 32
Fahrenheit to Celsius	°C = (°F - 32) × 5/9

Key reference values:

Celsius (°C)	Fahrenheit (°F)	Clinical Significance
36.1 - 37.2	97 - 99	Normal body temperature
37.5	99.5	Low-grade fever
38.0	100.4	Fever (pyrexia)
39.0	102.2	High fever
40.0	104.0	Very high fever
41.0	105.8	Hyperpyrexia
35.0	95.0	Hypothermia
100	212	Boiling point of water
0	32	Freezing point of water

Quick trick: To convert 37°C → °F: (37 × 9/5) + 32 = 66.6 + 32 = 98.6°F

2. HAND WASHING (WHO 6-Step Technique)

As described in Park's Textbook of Preventive and Social Medicine

Purpose: Remove transient microorganisms, prevent hospital-acquired infections (HAIs), break the chain of infection.

When to wash hands (5 Moments - WHO):

Before touching a patient
Before a clean/aseptic procedure
After body fluid exposure risk
After touching a patient
After touching patient surroundings

Steps of Hand Washing Technique (Soap & Water - minimum 40-60 seconds):

Step	Action
1	Wet hands with water
2	Apply enough soap to cover all hand surfaces
3	Rub palms together (palm to palm)
4	Rub back of each hand with palm of other hand, fingers interlocked
5	Rub palm to palm with fingers interlocked
6	Rub backs of fingers to opposing palms with fingers interlocked
7	Rotational rubbing of left thumb clasped in right palm and vice versa
8	Rub tips of fingers in opposite hand with rotational movement
9	Rinse hands with water
10	Dry thoroughly with a single-use towel
11	Use the towel to turn off the tap

Alcohol-based handrub: Use when hands are not visibly soiled - 20-30 seconds, same 6 steps.

3. BMI (Body Mass Index)

Formula:

BMI = Weight (kg) / Height² (m²)

Example: Weight = 70 kg, Height = 1.70 m → BMI = 70 / (1.70)² = 70 / 2.89 = 24.2 kg/m²

WHO BMI Classification:

BMI (kg/m²)	Classification
< 18.5	Underweight
18.5 - 24.9	Normal weight
25.0 - 29.9	Overweight (Pre-obese)
30.0 - 34.9	Obese Class I
35.0 - 39.9	Obese Class II
≥ 40.0	Obese Class III (Morbid obesity)

Nursing implications: BMI guides nutritional assessment, risk screening for diabetes, hypertension, CVD. Document and report abnormal BMI. - Goldman-Cecil Medicine

4. VITAL SIGNS

The 4 Primary Vital Signs:

A. Temperature

Normal: 36.1 - 37.2°C (97 - 99°F)
Sites: Oral, Axillary (subtract 0.5°C), Rectal (add 0.5°C), Tympanic
Axillary temperature is lowest; rectal is highest and most accurate

B. Pulse (Heart Rate)

Normal adults: 60 - 100 bpm
Bradycardia: < 60 bpm | Tachycardia: > 100 bpm
Assess: rate, rhythm, volume (strength), equality
Best sites: Radial (routine), Carotid (emergency), Apical (1 full minute)

C. Respiration

Normal adults: 12 - 20 breaths/min
Bradypnoea: < 12 | Tachypnoea: > 20
Count for 1 full minute; observe rise and fall of chest
Never tell patient you are counting (they will alter breathing)

D. Blood Pressure

Normal: < 120/80 mmHg
Hypertension: ≥ 130/80 mmHg (AHA) or ≥ 140/90 mmHg (WHO)
Hypotension: < 90/60 mmHg
Measure in sitting position, after 5 min rest, arm at heart level

Additional: Oxygen Saturation (SpO₂)

Normal: 95 - 100%
Concern: < 92% requires intervention

Vital Signs - Normal Adult Reference Table:

Parameter	Normal Range	Tool Used
Temperature	36.1 - 37.2°C	Thermometer
Pulse	60 - 100 bpm	Watch + fingers
Respiration	12 - 20/min	Observation
Blood Pressure	120/80 mmHg	Sphygmomanometer
SpO₂	95 - 100%	Pulse oximeter

5. BANDAGING

From Pye's Surgical Handicraft, 22nd Edition

Types of Bandages:

Type	Use
Roller bandage	Most common - limbs, head
Triangular bandage	Sling, first aid
T-bandage	Perineal/groin dressings
Tubular bandage	Fingers, toes
Elastic/Crepe bandage	Compression, stump

Basic Turns in Bandaging:

Turn	Technique	Area Used
Circular	Each layer directly over the previous	Wrist, ankle
Spiral	Each layer overlaps 1/2 to 2/3 of previous	Cylindrical limbs
Reverse spiral (Spica)	Bandage reversed at each turn	Conical limbs
Figure-of-eight	Alternating oblique turns above & below joint	Joints (knee, elbow, ankle)
Recurrent (Capeline)	Back-and-forth turns over terminal end	Stump, fingertip, head

Principles of Good Bandaging:

Begin from the distal end and proceed proximally
Overlap each turn by 1/2 to 2/3 of the width
Apply uniform, firm pressure - not too tight (check circulation) or too loose (slips off)
Always leave fingertips/toe tips exposed to check circulation
Check for: pallor, cyanosis, swelling, numbness, coldness (signs of impaired circulation)
Secure the end with a safety pin or tape - never a metal clip near a wound

Stump Bandaging: Figure-of-eight turns applied to condition stump post-amputation - prevents oedema, encourages venous return, tones tissue. Must be applied from time of amputation. - Pye's Surgical Handicraft

T-bandage (Perineal): Belt passed around waist; single or double tails passed between legs and secured. Used for perineal and groin dressings.

6. BIOMEDICAL WASTE MANAGEMENT

Governed by: Bio-Medical Waste (Management & Handling) Rules, 1998 (India) - amended 2016/2018

Color-Coded Segregation (MUST memorize):

Bag/Container Color	Waste Type	Disposal Method
🟡 Yellow	Human anatomical waste, animal waste, soiled waste (blood-soaked), expired medicines	Incineration / deep burial
🔴 Red	Contaminated plastic waste (syringes without needles, IV sets, catheters, urine bags)	Autoclaving → recycling
🔵 Blue / White Translucent	Glass waste, metallic implants, sharps	Autoclaving / microwaving → landfill
⬛ Black	General solid waste (non-biomedical)	Municipal solid waste disposal

Sharps Management:

Never recap needles with two hands (one-hand scoop technique only)
Dispose directly into puncture-proof sharps container (never overfill beyond 3/4)
Sharps containers: white/blue translucent, labeled

Key Principle - Segregation at source: Waste must be segregated at the point of generation (bedside). Never mix categories.

Chain of Waste Management:

Segregation → Collection → Transportation → Treatment → Disposal

7. HAIR CARE

Purpose: Maintain cleanliness, prevent infection (pediculosis/lice), promote comfort, assess scalp condition, maintain patient dignity.

Procedure - Hair Combing:

Position: Sitting if possible; for bedridden - Fowler's or lateral position with towel under head
Drape towel around shoulders
Divide hair into sections
Start combing from ends to roots to prevent pulling and breakage
Use wide-toothed comb for tangled hair
Assess for: dandruff, pediculosis (lice/nits), scalp lesions, alopecia

Bed Shampoo (for bedridden patients):

Gather: shampoo, basin, jug of warm water, waterproof sheet, towels, trough/Kelly pad
Position patient at edge of bed; protect mattress with waterproof sheet
Place trough/Kelly pad under head to channel water into basin
Wet hair, apply shampoo, massage gently with fingertips (not nails)
Rinse thoroughly (no residue left - causes dandruff)
Dry with towel, then dryer if available
Comb and style

Pediculosis Treatment:

Apply prescribed pediculicide lotion, leave for prescribed time
Use fine-toothed nit comb to remove nits
Wash all bedding/clothing

8. POSITIONING

Purpose: Prevent pressure ulcers, facilitate breathing, aid drainage, post-operative positioning, comfort, diagnostic/therapeutic purposes.

Standard Nursing Positions:

Position	Description	Uses
Supine (Dorsal recumbent)	Lying flat on back, arms at sides	General examination, post-anaesthesia
Prone	Lying face down	Back surgery, prevent pressure on sacrum, improve oxygenation (ARDS)
Lateral (Side-lying)	Lying on either side, pillow between knees	Preventing pressure ulcers, enema, unconscious patient
Fowler's	Head of bed 45-60° elevated	Respiratory difficulty, NG feeding, cardiac patients
Semi-Fowler's	30-45° elevation	Comfort, post-abdominal surgery
High Fowler's	60-90° (near sitting)	Severe respiratory distress, eating
Trendelenburg	Foot end raised 15-30° above head	Shock (controversial), perineal surgery, postural drainage
Modified Trendelenburg	Only legs elevated, body flat	Hypovolemic shock
Reverse Trendelenburg	Head end raised, body straight	Head/neck surgery, GERD
Lithotomy	On back, thighs flexed on abdomen, legs on stirrups	Gynaecological procedures, catheterization
Sims' (Semi-prone)	On left side, upper knee drawn up	Enema, rectal examination, unconscious patient
Knee-Chest (Genupectoral)	On knees and chest, head down	Rectal/sigmoid examination, posterior vaginal prolapse

Repositioning Schedule: Reposition every 2 hours to prevent pressure ulcers in bedridden patients.

9. PHYSICAL EXAMINATION

Purpose: Systematic assessment to determine health status, plan and evaluate care.

Techniques (IPPA - in order):

Technique	Method	Notes
I - Inspection	Visual observation	First step - never skip
P - Palpation	Touch/feel	Light before deep palpation
P - Percussion	Tapping to assess resonance	Distinguish solid vs. hollow organs
A - Auscultation	Listening with stethoscope	Always LAST (except for abdomen: IPAP)

Note for Abdomen: Order is Inspection → Auscultation → Palpation → Percussion (auscultate before palpating to avoid altering bowel sounds)

Systematic Head-to-Toe Assessment Sequence:

General appearance - level of consciousness, hygiene, distress
Head & Hair - symmetry, lesions, hair texture
Eyes - PERRLA (Pupils Equal, Round, Reactive to Light and Accommodation)
Ears - hearing, discharge
Nose & Mouth - mucous membranes, teeth, throat
Neck - lymph nodes, thyroid, JVD
Chest/Respiratory - breath sounds (vesicular, bronchial, bronchovesicular)
Cardiovascular - heart sounds S1 (mitral/tricuspid closure), S2 (aortic/pulmonic closure)
Abdomen - bowel sounds (normal 5-30/min), tenderness
Extremities - pulses, oedema, reflexes
Neurological - GCS, cranial nerves, motor/sensory

Breath Sounds:

Sound	Location	Character
Vesicular	Peripheral lung fields	Soft, low-pitched, inspiration > expiration
Bronchovesicular	Main bronchi area	Medium pitch, equal I:E ratio
Bronchial (Tubular)	Over trachea	Loud, high-pitched, expiration > inspiration

Abnormal Breath Sounds:

Crackles (Crepitations): Fluid in airways - pneumonia, pulmonary oedema
Wheeze: Bronchospasm - asthma, COPD
Stridor: Upper airway obstruction - emergency
Pleural friction rub: Pleuritis
