Here is your complete Nursing Reference Guide covering all 35 topics - step-by-step, practical, and designed for practicing nurses.
NURSING REFERENCE GUIDE
For Practicing Nurses | Moderate Clinical Detail
1. HAND HYGIENE
When to perform (WHO 5 Moments):
- Before touching a patient
- Before a clean/aseptic procedure
- After body fluid exposure risk
- After touching a patient
- After touching patient surroundings
Techniques:
- Alcohol-based handrub (ABHR): 60-95% ethanol; preferred for most situations. Apply 3-5 mL, rub all surfaces (6 steps) for 20-30 seconds until dry. Kills gram+/gram- bacteria, lipophilic viruses (HIV, influenza, HSV).
- Soap and water: Required for Clostridioides difficile and Bacillus anthracis (spores not killed by alcohol). Wet hands, apply soap, scrub 20-40 seconds, rinse, dry with single-use towel.
Surgical hand scrub: 3-5 minute scrub with antiseptic soap OR 1.5 min with alcoholic scrub preparation.
Key points:
- Compliance studies consistently show ~40% adherence to guidelines - the most preventable cause of HAI
- Resident flora (deep folds) vs. transient flora (surface) - transient flora is the main source of HAIs
- Remove rings and watches before hand hygiene - they harbor organisms under them
- Chlorhexidine gluconate has residual antimicrobial activity (6+ hours)
2. BED MAKING
Types:
| Type | When Used |
|---|
| Closed bed | Unoccupied, awaiting admission |
| Open bed | Awaiting ambulatory patient |
| Occupied bed | Patient confined to bed |
| Surgical/post-op bed (Anaesthetic bed) | Post-anaesthesia/surgical patients |
Steps - Occupied Bed Making:
- Explain procedure, ensure privacy
- Lower side rail on your side, raise bed to working height
- Loosen bottom sheet, turn patient to far side
- Roll soiled linen close to patient's back, tuck clean linen in and roll the excess against soiled linen
- Turn patient over the rolled linen to opposite side
- Remove soiled linen, unroll and tuck clean linen
- Replace top sheet, blanket, and spread
- Change pillowcases - shake pillows away from patient
- Return bed to lowest position, raise side rails
Principles: Never shake linen (aerosol spread). Hold linen away from uniform. Place soiled linen directly in hamper, not on floor.
3. DONNING AND DOFFING OF PPE
Sequence for DONNING (putting on):
- Perform hand hygiene
- Gown (tie at neck and waist)
- Mask/respirator (N95 for airborne)
- Eye protection/face shield
- Gloves (over gown cuffs)
Sequence for DOFFING (removing) - most critical step:
- Gloves first (most contaminated) - peel from wrist, invert as removed, discard
- Eye protection - remove from behind, avoid front
- Gown - unfasten ties, peel from neck/shoulders, roll away from body, discard
- Mask/respirator - remove from behind, do NOT touch front
- Hand hygiene after each step
Key rule: The FRONT of all PPE is considered contaminated. Always remove by touching only the back/straps.
N95 fit check: Positive pressure check (breathe out - no air should leak). Negative pressure check (inhale sharply - mask should collapse slightly against face).
4. GLOVING TECHNIQUE
Open Gloving (for non-sterile procedures):
- Remove gloves from the inner package
- First glove: grasp cuffed edge with opposite hand, pull on
- Second glove: slide gloved fingers under cuff of second glove, pull on
- Interlock fingers to smooth fit
Closed Gloving (sterile, surgical):
- Hands remain inside gown cuffs throughout
- Pick up first glove through gown sleeve
- Place glove on gown-covered hand (thumb-side facing body, fingers toward elbow)
- Fold cuff over sleeve end, pull through while keeping hand inside gown
- Repeat for second glove
Removing gloves (non-sterile):
- Grasp outside of one glove at wrist - peel off inverting it
- Hold removed glove in gloved hand
- Insert fingers of bare hand inside cuff of remaining glove - peel off
- Discard both, perform hand hygiene immediately
5. PERSONAL HYGIENE CARE
Bed Bath
Full bed bath steps:
- Gather supplies; explain procedure; provide privacy
- Water temperature: 43-46°C (110-115°F); change water when cool/soiled
- Order: face → neck → arms (far arm first) → chest → abdomen → legs (far leg first) → back → perineum
- Use long firm strokes; rinse and pat dry each area
- Apply lotion to prevent skin breakdown
Eye Care
- Clean from inner to outer canthus with moistened gauze
- Use a fresh swab for each wipe; separate swabs for each eye
- Unconscious patients: artificial tears q2h; eye shield if corneal reflex absent
Ear Care
- Clean external ear only with cloth-covered finger or washcloth
- Never insert cotton swabs into ear canal - risk of impaction and injury
- Note any discharge, odor, or lesions
Nail Care
- Soak fingernails in warm water 10-15 min before trimming
- Cut fingernails straight across, round edges with file
- Toenails: cut straight across (especially diabetic patients - never cut corners)
- Diabetic patients: refer to podiatrist for nail care
Indwelling Catheter Care (Foley Care)
- Perform 2x daily and after each bowel movement
- Cleanse urethral meatus with soap and water (or antiseptic wipe) in a front-to-back motion
- Secure catheter to inner thigh (female) or upper thigh/lower abdomen (male) to prevent traction
- Maintain drainage bag below bladder level at all times - never on the floor
- Keep tubing free of kinks; ensure closed drainage system is unbroken
- Empty bag when 2/3 full or every 8 hours; document output
6. BIOMEDICAL WASTE MANAGEMENT
Color-coded bag/container system (as per biomedical waste rules):
| Color | Container Type | Waste Category |
|---|
| Yellow | Bag/container | Anatomical/pathological waste, soiled dressings, body fluids |
| Red | Bag | Contaminated recyclable waste (IV sets, catheters, gloves) |
| White/Translucent | Puncture-proof container | Sharps (needles, blades, glass) |
| Blue | Box | Glassware |
Key principles:
- Waste segregation at point of generation - the nurse's direct responsibility
- Sharps: fill puncture-proof container to 3/4 full only; never recap needles (one-hand scoop technique if required)
- No mixing of waste categories
- Log and label each container: date, ward, type of waste
- Do not compact or compress yellow bags
7. VITAL SIGNS
Normal adult values and technique:
| Parameter | Normal Range | Key Points |
|---|
| Temperature | 36.5-37.5°C (97.7-99.5°F) | Oral most common; rectal = 0.5°C higher; axillary = 0.5°C lower |
| Pulse | 60-100 bpm | Count for 60 sec (arrhythmia) or 30 sec x2; assess rate, rhythm, volume |
| Respirations | 12-20 breaths/min | Count without patient awareness (after pulse); note depth and pattern |
| Blood Pressure | <120/80 mmHg | Rest 5 min before; arm at heart level; correct cuff size |
| SpO₂ | 95-100% | Probe on finger; poor signal if cold extremities, nail polish, or low perfusion |
Temperature sites: Oral (most common), rectal (most accurate), tympanic, axillary, temporal artery.
Postural BP: Check lying, sitting, standing. A drop >20 mmHg systolic or >10 mmHg diastolic = orthostatic hypotension.
8. O₂ DELIVERY SYSTEMS
| Device | FiO₂ Range | Flow Rate | Indications |
|---|
| Nasal Cannula | 24-44% | 1-6 L/min | Mild hypoxia, chronic use |
| Simple Face Mask | 35-55% | 6-10 L/min | Moderate hypoxia |
| Partial Non-Rebreather | 40-70% | 6-10 L/min | Moderate-severe hypoxia |
| Non-Rebreather Mask (NRM) | 60-90% | 10-15 L/min | Severe hypoxia (CO poisoning, trauma) |
| Venturi Mask | Precise 24-60% | Variable | COPD (controlled O₂ delivery) |
| CPAP/BiPAP | Up to 100% | Variable | Respiratory failure, sleep apnea |
| Endotracheal Tube (ETT) | Up to 100% | Ventilator set | Mechanical ventilation |
Nursing responsibilities:
- Ensure humidification for flow >4 L/min (nasal cannula) or all face mask use
- Monitor SpO₂ continuously; titrate to target (usually SpO₂ 94-98%; COPD: 88-92%)
- Check for skin breakdown under mask straps and at nares
- Ensure reservoir bag inflated on NRM before placing on patient
9. ISOLATION PRECAUTIONS
Standard Precautions (ALL patients, ALL times):
- Hand hygiene
- Gloves for contact with blood/body fluids
- Gown, mask, eye protection based on anticipated splatter risk
- Respiratory hygiene/cough etiquette
- Safe injection practices
- Sharps disposal
Transmission-Based Precautions:
| Type | Diseases | PPE | Room |
|---|
| Contact | MRSA, VRE, C. diff, scabies, wound infections | Gown + gloves | Single room preferred |
| Droplet | Influenza, meningitis, pertussis, COVID-19 | Surgical mask + eye protection | Single room; door can be open |
| Airborne | TB, measles, chickenpox, COVID-19 (aerosol procedures) | N95 respirator + eye protection | Negative pressure room; door closed |
Protective (Reverse) Isolation: For severely immunocompromised patients. Visitors and staff wear mask, gown, gloves to protect the patient.
10. COMFORT DEVICES AND POSITIONS
Therapeutic Positions:
| Position | Use |
|---|
| Fowler's (30-90°) | Post-op, respiratory distress, feeding, nasogastric tube care |
| Semi-Fowler's (30-45°) | VAP prevention, NG feeds, cardiac patients |
| Supine | Spinal injury, post-anaesthesia |
| Prone | ARDS (improves oxygenation), pressure ulcer prevention (turns) |
| Lateral (side-lying) | Unconscious patients (prevents aspiration), during log roll |
| Sims' | Enema, rectal examination, unconscious patients |
| Trendelenburg | Hypovolemic shock (elevate legs 30°; avoid full Trendelenburg) |
| Reverse Trendelenburg | GERD, head/neck surgery |
| Lithotomy | Urinary catheterization, pelvic examination |
Comfort Devices:
- Pillows: Support limbs, maintain alignment, pressure relief
- Foam wedges: Maintain lateral tilt (30°) for pressure relief; knee flexion
- Heel protectors/boots: Offload heels (highest-risk pressure area in supine patients)
- Bed cradle: Keep linen off lower limbs (burns, ulcers)
- Splints/footboards: Prevent foot drop in bed-bound patients
- Anti-embolism (TED) stockings: DVT prevention; measure and fit correctly
11. PAIN ASSESSMENT
OLDCART mnemonic:
- O - Onset: When did it start?
- L - Location: Where is the pain?
- D - Duration: How long does it last?
- C - Character: What does it feel like?
- A - Aggravating factors
- R - Relieving factors
- T - Treatment tried
General principles:
- Pain is the "5th vital sign" - assess with every vital sign check
- Self-report is the most reliable measure when patient is able to communicate
- Assess pain at rest AND with movement (procedural pain)
- Reassess after every intervention (within 30-60 min for analgesics)
12. PQRST PAIN ASSESSMENT
| Letter | Meaning | Sample Questions |
|---|
| P - Provocation/Palliation | What makes it better or worse? | "What were you doing when it started? What makes it better?" |
| Q - Quality | What does it feel like? | "Burning, stabbing, crushing, throbbing, aching?" |
| R - Region/Radiation | Where is it? Does it spread? | "Show me where it hurts. Does it go anywhere else?" |
| S - Severity | How bad is it? (scale 0-10) | "On a scale of 0 to 10, how bad is it right now?" |
| T - Timing | When? Constant or intermittent? | "How long have you had it? Is it constant or does it come and go?" |
Clinical application: PQRST is especially useful for cardiac chest pain - radiation to jaw/left arm (Q), crushing quality (Q), and severity (S) help distinguish STEMI from other causes.
13. NUMERIC RATING SCALE (NRS)
- Simple 0-10 horizontal scale
- 0 = No pain | 1-3 = Mild | 4-6 = Moderate | 7-10 = Severe
- Patient verbally or visually selects a number
Interpretation and action:
| Score | Category | Typical Action |
|---|
| 0 | No pain | Reassess per schedule |
| 1-3 | Mild | Non-pharmacological measures (repositioning, heat/cold, distraction) |
| 4-6 | Moderate | Non-opioid analgesics (paracetamol, NSAIDs); notify physician |
| 7-10 | Severe | Strong analgesics; immediate physician notification |
Limitation: Requires patient ability to understand numeric concepts. Use alternative scales for cognitive impairment.
14. WONG-BAKER FACES SCALE
- 6 face drawings from happy (0) to crying (10)
- Used for: children aged 3+, patients with language barriers, cognitive impairment, or difficulty with numbers
| Face | Score | Description |
|---|
| 😊 | 0 | No hurt |
| 🙂 | 2 | Hurts little bit |
| 😐 | 4 | Hurts little more |
| 😟 | 6 | Hurts even more |
| 😢 | 8 | Hurts whole lot |
| 😭 | 10 | Hurts worst |
Instruction to patient: "Point to the face that shows how much you are hurting right now."
15. GLASGOW COMA SCALE (GCS)
| Component | Response | Score |
|---|
| Eye Opening (E) | Spontaneous | 4 |
| To voice/command | 3 |
| To pain | 2 |
| None | 1 |
| Verbal Response (V) | Oriented | 5 |
| Confused | 4 |
| Inappropriate words | 3 |
| Incomprehensible sounds | 2 |
| None | 1 |
| Motor Response (M) | Obeys commands | 6 |
| Localizes pain | 5 |
| Withdraws from pain | 4 |
| Abnormal flexion (decorticate) | 3 |
| Extension (decerebrate) | 2 |
| None | 1 |
Total = E + V + M (range 3-15)
| GCS Score | Severity |
|---|
| 13-15 | Mild brain injury |
| 9-12 | Moderate brain injury |
| 3-8 | Severe brain injury |
| ≤8 | Airway at risk - consider intubation |
Always use BEST response for scoring. Document individual scores (e.g., E3V4M5 = GCS 12) not just total.
(Clinical Procedures in Emergency Medicine)
16. LOG ROLLING METHOD
Indication: Patients with suspected or confirmed spinal injury (cervical, thoracic, or lumbar).
Requires: Minimum 3-4 staff members (1 at head, 2 at body, 1 receives board).
Steps:
- Leader at head (maintains cervical spine alignment manually - two-hand hold on sides of head)
- Communicate clearly - leader gives all commands
- Position: one assistant at shoulders/upper chest, one at hips/thighs, one at lower legs
- Command "Ready... Roll" - patient turned as a single rigid unit (no twisting of spine)
- Turn to lateral position (usually for board placement or assessment)
- Insert spinal board, return patient supine on command
Key principles:
- Neutral spine alignment maintained throughout
- No pillow during transport if cervical collar in place
- If 3 staff only: leader at head, one at torso, one at legs
- Maintain cervical collar (hard collar) until C-spine cleared
17. CANNULATION PROCEDURE (IV Cannula Insertion)
Equipment: IV cannula (appropriate size), tourniquet, antiseptic swab, transparent dressing, IV flush (normal saline), gloves, sharps bin.
Cannula size selection:
| Size (Gauge) | Color | Use |
|---|
| 14G | Orange | Massive transfusion, trauma |
| 16G | Grey | Blood transfusion, surgery |
| 18G | Green | General IV therapy |
| 20G | Pink | Standard; IV fluids, medications |
| 22G | Blue | Elderly, children, fragile veins |
| 24G | Yellow | Neonates, very fragile veins |
Steps:
- Perform hand hygiene; apply gloves
- Select vein (antecubital fossa, forearm, dorsal hand); avoid antecubital if mobility needed
- Apply tourniquet 7-10 cm above site; ask patient to pump fist
- Clean with 70% alcohol swab; allow to dry 30 seconds (do not fan or blow dry)
- Anchor vein with non-dominant thumb; insert cannula at 15-30° angle bevel-up
- Advance until flashback of blood seen in chamber
- Lower angle, advance 2-3 mm further, then slide plastic cannula off needle into vein
- Release tourniquet; press over vein proximal to tip while removing needle
- Immediately discard needle in sharps bin (do NOT recap)
- Attach cap, flush with 5 mL normal saline - observe for swelling (infiltration), pain
- Apply transparent dressing; date and label (date, time, gauge)
Complications: Infiltration, phlebitis, haematoma, infection. Check site every shift.
18. PARENTERAL MEDICATIONS
Intravenous (IV)
| Route | Speed | Use |
|---|
| IV bolus (push) | Over 1-5 min | Emergency drugs, bolus doses |
| IV piggyback (IVPB) | Over 15-60 min | Antibiotics, most IV drugs |
| IV infusion | Continuous | Fluids, vasopressors, insulin |
- Always check compatibility before mixing
- Flush IV line before and after each drug
- Monitor IV site for phlebitis, infiltration
Intramuscular (IM)
| Site | Volume | Notes |
|---|
| Deltoid | ≤1 mL | Vaccines, small volumes |
| Vastus lateralis | Up to 5 mL | Infants, pediatrics; preferred self-injection |
| Ventrogluteal | Up to 3 mL | Safest IM site (no major nerves/vessels) |
| Dorsogluteal | Up to 5 mL | Avoid (risk of sciatic nerve injury) |
- Z-track technique for irritating medications (Iron, certain vaccines): pull skin 2-3 cm laterally before injection; hold 10 sec after; release skin before withdrawing
- Aspirate not required for most IM injections (per WHO/CDC 2015 guidelines)
Intradermal (ID)
- Site: Volar (inner) forearm
- Angle: 10-15° bevel-up
- Volume: 0.1 mL

19. ORAL MEDICATIONS
Rights of Medication Administration (10 Rights):
- Right patient (check 2 identifiers)
- Right medication
- Right dose
- Right route
- Right time
- Right documentation
- Right reason
- Right response (assess therapeutic effect)
- Right to refuse (document)
- Right education (explain to patient)
Steps:

- Check patient identity with 2 identifiers (name band + verbal confirmation)
- Assess swallowing ability; position upright (at least 45°)
- Administer with 100-200 mL of water (unless restricted)
- Remain with patient until medications are swallowed
- Document immediately after administration
Never crush: Enteric-coated, extended-release, sublingual tablets. Check if capsule can be opened.
20. PARTS OF SYRINGE AND NEEDLE
Syringe components:
- Tip - attaches to needle (Luer-lock or slip-tip)
- Barrel - transparent cylinder with measurement markings (mL)
- Plunger - piston that draws or expels fluid
- Flange - projections at base of barrel (finger grip during injection)
Needle components:
- Hub - attaches to syringe tip
- Shaft/Cannula - hollow cylindrical body
- Bevel - slanted cut at tip (creates sharp point; always bevel-up for ID/SC)
- Lumen - hollow core through which fluid passes
Gauge: Higher number = smaller diameter. Examples: 18G (IV, blood draw), 21-23G (IM), 25-27G (SC/ID).
Length: Depends on route: ID (10 mm), SC (16 mm), IM (25-38 mm), IV (various).
21. PREVENTION OF NEEDLE STICK INJURY (NSI)
High-risk activities: Recapping needles, disposal, phlebotomy, IV access.
Prevention strategies:
- No recapping (single most important rule) - use one-hand scoop technique ONLY if absolutely necessary
- Immediately discard used sharps in puncture-proof container at point of use
- Never leave sharps on bed/tray; never pass hand-to-hand
- Use safety-engineered devices (retractable needles, safety IV cannulas)
- Never overfill sharps containers (fill to 3/4 max)
- Wear gloves during all needle-related procedures
If NSI occurs - immediate management:
- Do NOT squeeze or suck the wound
- Wash immediately with soap and running water for ≥5 minutes
- Apply antiseptic (betadine or 70% alcohol)
- Report immediately to nurse in charge / occupational health
- Document: date, time, type of device, injury site, patient details
- Blood tests: HBV, HCV, HIV (baseline for both exposed and source patient)
- PEP (Post-Exposure Prophylaxis): HIV PEP within 72 hours; HBsIg if not immunized
22. PRESSURE SORES - PREVENTION AND MANAGEMENT
Staging (NPUAP/EPUAP):
| Stage | Description |
|---|
| Stage 1 | Non-blanchable erythema on intact skin |
| Stage 2 | Partial thickness skin loss - open shallow ulcer, no slough |
| Stage 3 | Full thickness skin loss - subcutaneous fat visible; no bone/tendon |
| Stage 4 | Full thickness tissue loss - bone, tendon, or muscle exposed |
| Unstageable | Full thickness; base covered by slough/eschar |
| Deep Tissue Injury | Purple/maroon discoloration; intact skin |
Prevention (SSKIN bundle):
- S - Surface: Use appropriate pressure-redistributing mattress (foam, gel, air)
- S - Skin inspection: Every 2-4 hours; document findings
- K - Keep moving: Reposition every 2 hours (or q1h in chair)
- I - Incontinence: Keep skin clean and dry; use moisture barrier creams
- N - Nutrition: Adequate protein (1.0-1.5 g/kg/day), Vitamin C, Zinc, hydration
Management by stage:
- Stage 1: Remove pressure, moisturize, transparent film dressing
- Stage 2: Clean with NS, hydrocolloid dressing, offload pressure
- Stage 3: Debridement if needed, alginate/foam dressing, consider nutrition support
- Stage 4: Surgical evaluation (debridement/flap repair); VAC therapy; MDT involvement
23. BRADEN SCALE - PRESSURE SORE RISK ASSESSMENT
| Subscale | 1 (Highest Risk) | 2 | 3 | 4 (Lowest Risk) |
|---|
| Sensory Perception | Completely limited | Very limited | Slightly limited | No impairment |
| Moisture | Constantly moist | Very moist | Occasionally moist | Rarely moist |
| Activity | Bedfast | Chairfast | Walks occasionally | Walks frequently |
| Mobility | Completely immobile | Very limited | Slightly limited | No limitation |
| Nutrition | Very poor | Probably inadequate | Adequate | Excellent |
| Friction & Shear | Problem | Potential problem | No apparent problem | - |
Scoring (range 6-23):
| Score | Risk Level | Action |
|---|
| ≤9 | Very high risk | Hourly repositioning, advanced mattress, MDT referral |
| 10-12 | High risk | 2-hourly turns, pressure-relieving devices |
| 13-14 | Moderate risk | 4-hourly repositioning |
| 15-18 | Mild risk | Prevention protocol |
| 19-23 | No risk | Routine skin care |
Assess on admission, with every significant clinical change, and per institutional policy (usually daily in acute care).
24. VACUUM ASSISTED COMPRESSION (VAC/NPWT)
Indication: Grade 3-4 pressure sores, chronic non-healing wounds, post-debridement wounds.
How it works: Applies continuous or intermittent sub-atmospheric pressure (-75 to -125 mmHg) to wound bed, removing exudate, reducing edema, promoting granulation tissue formation and angiogenesis.
Components: Foam dressing (black polyurethane or white polyvinyl alcohol), transparent drape, tube, canister, therapy unit.
Procedure:
- Clean wound with normal saline; debride necrotic tissue as ordered
- Measure and cut foam to fit wound (do NOT pack tightly - foam should loosely fill cavity)
- Place foam in wound, cover with occlusive transparent drape (extend 3-5 cm onto perilesional skin)
- Make small hole in drape (or use provided pad); attach therapy tube
- Connect to VAC unit; set pressure as prescribed (typically -125 mmHg continuous)
- Ensure airtight seal - foam should collapse (shrink) when activated
- Change dressing every 48-72 hours (more frequently if infected)
Contraindications: Untreated osteomyelitis, malignancy in wound, fistulas to organs/body cavities, exposed blood vessels/nerves.
25. URINARY CATHETERIZATION
Male Catheterization
- Gather sterile equipment; explain procedure; position supine
- Hand hygiene, don sterile gloves, create sterile field
- Drape patient; retract foreskin (if present); clean glans with antiseptic 3x in circular motion
- Apply 10 mL of 2% lignocaine gel into urethra; wait 5 minutes
- Grasp penis at 90° angle to abdominal wall; insert catheter until bifurcation ("Y" junction)
- Inflate balloon with 10 mL sterile water (ONLY once urine flows)
- Gentle traction to confirm balloon seated at bladder neck
- Replace foreskin to prevent paraphimosis
- Attach drainage bag; secure catheter to thigh with tape
Female Catheterization
- Position in dorsal recumbent (supine, knees bent, feet flat)
- Cleanse labia majora → minora → urethral meatus (front to back, separate wipes)
- Insert lubricated catheter 5-7 cm until urine flows
- Inflate balloon; gentle traction; secure to inner thigh
Common catheter sizes: 12-14 Fr (female), 14-16 Fr (male). Standard balloon: 10 mL.
Indication mnemonic (ABCDE): Accurate output measurement, Bladder obstruction, Comfort in terminal illness, Decubitus ulcer healing (sacral), Extended surgery.
26. FLUID DRIP RATE CALCULATION
Formula:
Drops per minute = (Volume in mL × Drop factor) ÷ Time in minutes
Standard drop factors:
- Macrodrip (standard): 15 gtts/mL or 20 gtts/mL
- Microdrip (pediatric): 60 gtts/mL
Example: 1000 mL NS over 8 hours, macrodrip (15 gtts/mL)
- Time = 8 × 60 = 480 minutes
- Drip rate = (1000 × 15) ÷ 480 = 31.25 ≈ 31 drops/min
mL/hr calculation (for infusion pumps):
mL/hr = Total volume (mL) ÷ Total time (hours)
Example: 500 mL over 4 hours = 500 ÷ 4 = 125 mL/hr
27. NUTRITION ROUTES
| Route | Method | Indication |
|---|
| Oral | Normal eating/drinking | Functional swallowing |
| NG Tube | Nasogastric - nose to stomach | Short-term (<6 weeks), unable to swallow |
| OG Tube | Orogastric - mouth to stomach | Neonates; facial trauma preventing nasal route |
| PEG Feed | Percutaneous Endoscopic Gastrostomy | Long-term enteral feeding; swallowing disorder |
| J-tube | Jejunostomy | Gastric motility issues, high aspiration risk |
| TPN | Total Parenteral Nutrition (IV) | Non-functional gut, bowel rest required |
NG Tube verification (before each feed):
- Aspirate stomach contents - pH ≤5.5 confirms gastric placement
- Chest X-ray is gold standard (especially on initial insertion)
- NEVER use the auscultation ("whoosh") method alone - unreliable
Enteral feeding care:
- Check gastric residual volume (GRV) every 4-6 hours; hold feed if >200-500 mL (per protocol)
- Keep HOB elevated ≥30-45° (VAP prevention)
- Flush tube with 30 mL water before and after feeds, and with each medication
TPN monitoring: Blood glucose q4-6h (hyperglycemia common), electrolytes daily, liver function weekly.
28. BLOOD TRANSFUSION
Indications:
- Hb <7 g/dL (stable patients); <8 g/dL (cardiac patients or symptomatic anaemia)
- Acute haemorrhage with haemodynamic instability
- Coagulopathy, thrombocytopenia (specific products)
Blood Products:
| Product | Indication | Storage |
|---|
| Packed Red Blood Cells (PRBCs) | Anaemia, haemorrhage | 1-6°C; use within 4 hours of spiking |
| Fresh Frozen Plasma (FFP) | Coagulopathy, DIC, massive transfusion | Frozen; thaw before use |
| Platelets | Thrombocytopenia, platelet dysfunction | Room temp (22°C), agitate continuously |
| Cryoprecipitate | Factor deficiency, haemophilia A, vWD, DIC | Frozen |
| Whole Blood | Massive haemorrhage, military settings | 1-6°C |
Pre-transfusion Checklist:
- Informed consent
- Confirm prescription
- Two-nurse ID check: patient name, MRN, blood group, donation number, expiry
- Check for colour changes, clots, leakage in blood bag
- Baseline vitals: temperature, BP, HR, SpO₂
- Administer through IV cannula (16-18G preferred); blood transfusion set (170-230 micron filter)
- First 15 mL: infuse slowly (2 mL/min); remain at bedside for first 15 minutes
- If reaction suspected: STOP transfusion, keep IV line open with NS, notify doctor
Transfusion reactions: Febrile non-haemolytic (most common - fever/chills), acute haemolytic (most dangerous - back pain, dark urine), allergic, TRALI, TACO.
29. EMERGENCY MEDICATIONS
| Drug | Mechanism | Key Dilution/Dose | Indication |
|---|
| Adrenaline (Epinephrine) | α1+β1+β2 agonist - ↑HR, ↑BP, bronchodilation | 1 mg IV q3-5 min (1:10,000 = 0.1 mg/mL) | Cardiac arrest, anaphylaxis |
| Atropine | Anticholinergic - blocks vagus → ↑HR | 0.5-1 mg IV bolus (max 3 mg) | Bradycardia, organophosphate poisoning |

30. EMERGENCY NURSING MANAGEMENT - SELECTED SCENARIOS
1. Fever
- Rapid assessment: temperature, source (UTI, LRTI, meningitis, sepsis)
- Antipyretics: Paracetamol 500-1000 mg PO/IV; Ibuprofen (if no contraindication)
- Tepid sponging, remove excess clothing, ensure adequate hydration
- Cultures (blood, urine) BEFORE antibiotics if sepsis suspected
- Sepsis screening: qSOFA (confusion, RR>22, SBP<100) → NEWS/MEWS scoring
2. Myocardial Infarction (MI)
MONA protocol (for STEMI):
- Morphine 2-4 mg IV (pain, anxiety) - use cautiously; may mask symptoms
- Oxygen if SpO₂ <94% (do not routinely give if normoxic)
- Nitroglycerine sublingual (0.4 mg) - contraindicated if systolic BP <90 mmHg or right ventricular MI
- Aspirin 300 mg stat (chewed, not swallowed)
Plus: Heparin, P2Y12 inhibitor (Ticagrelor/Clopidogrel), primary PCI within 90 minutes
ECG within 10 minutes; 12-lead; IV access, continuous cardiac monitor, ready defibrillator
3. Stroke
FAST acronym: Face drooping, Arm weakness, Speech difficulty, Time to call
- Last known well time - critical for thrombolysis (tPA within 4.5 hours)
- CT head (non-contrast) immediately - rule out haemorrhage before tPA
- NIH Stroke Scale (NIHSS) assessment
- Nil by mouth (swallowing assessment before oral intake)
- BP management: Do NOT lower BP aggressively in ischaemic stroke unless >220/120
4. Head Injury
- C-spine immobilization (assume until cleared)
- ABC assessment; GCS scoring
- Pupils: equality and reaction to light (herniation = fixed dilated ipsilateral pupil)
- CT head - immediate in GCS ≤13
- ICP monitoring in severe TBI
- HOB 30°, avoid hypotension (MAP >70 mmHg), normothermia, normoglycaemia
5. Organophosphate (OP) Poisoning
SLUDGE symptoms (cholinergic excess): Salivation, Lacrimation, Urination, Defecation, GI distress, Emesis
Plus: Miosis, Bradycardia, Bronchospasm, Seizures
- Antidote: Atropine 2-4 mg IV every 5-10 min until secretions dry
- Pralidoxime (2-PAM) 1-2 g IV (within 24-48 hours of exposure - reactivates cholinesterase)
- Decontaminate (remove clothing, wash skin); wear PPE during decontamination
6. Snakebite
- Immobilize limb at heart level; remove rings/watches/tight clothing
- Do NOT: tourniquet, incise-and-suck, apply ice, electric shock
- Identify snake if possible (photo, not capture)
- Polyvalent antivenom based on signs: coagulopathy (haemotoxic), ptosis/paralysis (neurotoxic), local necrosis (cytotoxic)
- Monitor: CBC, coagulation (PT, INR, APTT), renal function, urine output (watch for haemoglobinuria)
7. Road Traffic Accident (RTA)
Primary Survey - ABCDE:
- A - Airway with C-spine control
- B - Breathing (pneumothorax, haemothorax)
- C - Circulation (haemorrhage control, 2 large bore IVs)
- D - Disability (GCS, pupils)
- E - Exposure (remove all clothing; log roll to check back)
Haemorrhage: "Permissive hypotension" in penetrating trauma (SBP 80-90 until surgical control); aggressive resuscitation in blunt trauma/TBI
8. Hypoglycaemia
- Blood glucose <3.9 mmol/L (70 mg/dL) = hypoglycaemia
- Conscious patient: 15-20 g fast-acting carbohydrates (4 glucose tablets, 150 mL orange juice); reassess in 15 min
- Unconscious/unable to swallow: 50 mL of 50% dextrose (D50W) IV bolus OR Glucagon 1 mg IM
- Continue monitoring glucose every 15 minutes; give complex carbohydrate once conscious
31. ICU CARE BUNDLES
VAP Bundle (Ventilator-Associated Pneumonia)
- HOB ≥30-45° (semi-recumbent) - reduces aspiration
- Daily sedation vacation + readiness-to-extubate assessment
- Peptic ulcer prophylaxis (PPI or H2 blocker)
- DVT prophylaxis (LMWH or sequential compression devices)
- Oral care with chlorhexidine 0.12% q4-6h (reduces oral bacterial colonization)

- Hand hygiene before insertion and access
- Maximum sterile barrier precautions during insertion (cap, mask, sterile gown, gloves, full drape)
- Chlorhexidine 2% skin antisepsis (dry before insertion)
- Optimal site selection - subclavian preferred (vs. femoral - highest risk)
- Daily review - remove line as soon as no longer necessary
- Use closed needleless access connectors; scrub the hub for ≥15 seconds before access
CAUTI Bundle (Catheter-Associated Urinary Tract Infection)
- Insert catheter only when indicated (avoid inappropriate catheterization)
- Sterile insertion technique

35. BASIC LIFE SUPPORT (BLS) / CPR
Adult BLS Sequence (AHA/ILCOR Guidelines):
- Ensure scene safety
- Check responsiveness - tap shoulders, shout "Are you okay?"
- Call for help - activate emergency response (111/999/911); get AED if available
- Check for breathing and pulse simultaneously - maximum 10 seconds
- If no pulse and no normal breathing → Begin CPR
CPR Technique:
- Position: Heel of hand on lower half of sternum; second hand on top; fingers interlocked; arms straight
- Depth: At least 2 inches (5 cm); no more than 2.4 inches (6 cm)
- Rate: 100-120 compressions per minute
- Ratio: 30 compressions : 2 breaths (30:2) - single or dual rescuer adult BLS
- Recoil: Allow full chest recoil between compressions; do not lean on chest
- Minimize interruptions: Pause ≤10 seconds for breaths or rhythm check
Rescue Breaths:
- Head tilt-chin lift (jaw thrust if C-spine injury suspected)
- Create seal; give breath over 1 second; watch for chest rise
- Do NOT hyperventilate
AED:
- Power on → Follow voice prompts
- Attach pads: one below right clavicle (right of sternum), one on left lateral chest (apex/V6 position)
- Analyse rhythm → Stand clear if shock advised
- Deliver shock → Immediately resume CPR
Chain of Survival:
Early recognition → Early CPR → Early defibrillation → Advanced care → Post-resuscitation care
