🏥 BSc Nursing 1st Year - OSCE Preparation Guide
1. TEMPERATURE - Measurement & Calculation
Sites and Normal Values
| Site | Normal Range | Notes |
|---|---|---|
| Oral (mouth) | 36.8°C (98.4°F) | Most common |
| Rectal | 37.0°C - 37.5°C | Most accurate (gold standard) |
| Axillary (armpit) | 36.4°C - 37.0°C | Least accurate, 0.5°C lower than oral |
| Tympanic (ear) | ~37°C | Quick, good for children |
Temperature Conversion Formula (VERY IMPORTANT for OSCE!)
Celsius to Fahrenheit:
°F = (°C × 9/5) + 32 Example: 37°C = (37 × 9/5) + 32 = 66.6 + 32 = 98.6°F
Fahrenheit to Celsius:
°C = (°F - 32) × 5/9 Example: 98.6°F = (98.6 - 32) × 5/9 = 66.6 × 5/9 = 37°C
Quick Conversions to Remember:
- 36°C = 96.8°F
- 37°C = 98.6°F ✅ (Normal)
- 38°C = 100.4°F (Fever/Pyrexia)
- 40°C = 104°F (High fever)
- 41°C = 105.8°F (Hyperpyrexia)
Types of Thermometers:
- Glass/Mercury thermometer - oral, rectal, axillary
- Electronic/Digital thermometer - fast, accurate
- Infrared/Tympanic thermometer - ear, quick
- Disposable thermometer - single use
2. POSITIONS / COMFORT DEVICES - Names & Uses

| Sand bag | Immobilise limbs, maintain position |
| Foot board | Prevent foot drop |
| Side rails | Prevent patient from falling |
| Bed cradle (Anderson frame) | Keep bed linen off wounds/limbs |
| Air ring (Donut cushion) | Prevent pressure sore on coccyx/buttocks |
| Trochanter roll | Prevent external rotation of hip |
| Hand roll | Maintain hand in functional position |
| Backrest | Support back in sitting position |
3. FOLEY'S CATHETER - Parts, Names & Uses
Parts of Foley's Catheter
| Part | Description | Use/Function |
|---|---|---|
| Tip (Rounded/Blind tip) | Rounded closed end with 2 eyes | Inserted into urethra, collects urine through eyes |
| Eyes/Eyelets | 2 holes near the tip | Allows urine to drain into catheter |
| Shaft/Tube | Main body of catheter | Carries urine from bladder to drainage bag |
| Balloon channel | Thin inner lumen | Inflate/deflate the balloon |
| Balloon | Inflatable cuff near tip | Anchors catheter inside the bladder |
| Inflation valve | Small port at the end | Where syringe attaches to inflate balloon |
| Drainage port/lumen | Larger port at end | Connects to urine drainage bag |
| Funnel end | Wide open end | Connected to urine collection bag |
Balloon sizes:
- 5 ml - Adults (standard)
- 10-30 ml - Post-surgical/haematuria
- 3-5 ml - Children
Catheter Fr (French) sizes:
- Adults female: 14-16 Fr
- Adults male: 16-18 Fr
- Children: 8-10 Fr
4. SYRINGE - Parts & Uses
Parts of a Syringe
| Part | Function |
|---|---|
| Barrel | Graduated cylindrical body - holds the fluid/medication |
| Plunger | Piston rod that pushes/pulls fluid |
| Plunger tip (Rubber seal) | Creates airtight seal inside barrel |
| Nozzle/Tip | Where needle attaches |
| Flange | Finger grip on sides of barrel |
| Graduation markings | Calibrated ml/cc measurements |
Types of Syringes:
- Luer-Slip - Needle just slips on tip
- Luer-Lock - Needle screws on (safer for IV)
- Insulin syringe - 1 ml, marked in units (100 units/ml)
- Tuberculin syringe - 1 ml, very fine graduation (0.01 ml)
5. OXYGEN ADMINISTRATION DEVICES - Name, Flow Rate & Concentration
| Device | Flow Rate (L/min) | O2 Concentration (FiO2) | Notes |
|---|---|---|---|
| Nasal Cannula (Prongs) | 1 L/min | ~24% | Low flow, comfortable |
| 2 L/min | ~28% | ||
| 4 L/min | ~35% | ||
| 6 L/min | ~40-44% | Max for nasal cannula | |
| Simple Face Mask | 5-6 L/min | 35-40% | Min 5 L to flush CO2 |
| 8-10 L/min | 50-60% | ||
| Partial Rebreathing Mask | 6-10 L/min | 50-60% | Has reservoir bag, no one-way valve |
| Non-Rebreathing Mask (NRM) | 10-15 L/min | 60-95% | Has one-way valves + reservoir bag, HIGHEST O2 delivery without ventilator |
| Venturi Mask | 2-15 L/min | 24%, 28%, 31%, 35%, 40%, 60% | Fixed, precise FiO2; best for COPD |
Rule of thumb for nasal cannula:
Each 1 L/min increase = ~4% increase in O2 concentration Starting from room air = 21%
6. NG TUBE INSERTION - Procedure Steps
Equipment Needed:
- NG tube (Ryle's tube) - appropriate size (Fr 16-18 adult)
- Lubricant (water-soluble jelly / KY jelly)
- Kidney tray, tissue/towel, stethoscope
- 50 ml syringe
- Litmus paper / pH paper (to check placement)
- Adhesive tape, gloves, apron
Procedure Steps:
1. Preparation
- Wash hands (6 steps)
- Explain procedure to patient, get consent
- Position patient: Semi-Fowler's (45-60°) or High Fowler's
- Place towel over chest
2. Measure the tube
- Measure from tip of nose → earlobe → xiphisternum (bottom of sternum)
- Mark this point on the tube (NEX measurement)
3. Lubricate
- Apply water-soluble lubricant to the first 15-20 cm of the tube tip
4. Insert the tube
- Ask patient to tilt head slightly forward (chin to chest)
- Insert through the more patent nostril (check which nostril is clear)
- Advance gently along the floor of the nasal passage
- When tube reaches the pharynx (back of throat) - ask patient to swallow (give sips of water if allowed)
- Advance tube with each swallow until marked level reached
5. Confirm placement (CRITICAL OSCE POINT)
Three methods:
- Aspirate gastric juice - test with pH paper (pH should be ≤5.5 = gastric)
- Auscultation - inject 20 ml air with syringe while listening with stethoscope over epigastrium - hear "whooshing" sound
- X-ray - gold standard / most reliable
6. Secure the tube
- Fix with adhesive tape on nose/cheek
- Document tube position and NEX measurement
7. Aftercare
- Wash hands
- Document in patient notes
- Keep patient in Semi-Fowler's during feeding
7. HAND WASHING - WHO 6-Step Technique
When to wash hands (5 Moments):
- Before touching a patient
- Before a clean/aseptic procedure
- After body fluid exposure risk
- After touching a patient
- After touching patient surroundings
6-Step WHO Technique (takes 40-60 seconds with soap and water):
| Step | Action |
|---|---|
| Step 1 | Wet hands → Apply enough soap to cover all surfaces |
| Step 2 | Palm to palm - Rub hands together |
| Step 3 | Right palm over left back of hand with interlaced fingers, then repeat other side |
| Step 4 | Palm to palm with fingers interlaced |
| Step 5 | Backs of fingers to opposing palms with fingers interlocked |
| Step 6 | Rotational rubbing of thumb in opposite hand |
| Step 7 | Rotational rubbing of fingertips/nails in palm of opposite hand |
| Step 8 | Rub each wrist with opposite hand |
| Step 9 | Rinse with water, use elbow to turn off tap |
| Step 10 | Dry thoroughly with single-use towel |
Duration: 40-60 seconds (soap & water) | 20-30 seconds (alcohol hand rub)
Alcohol Hand Rub: used when hands are not visibly soiled (takes 20-30 seconds)
