I now have sufficient sourced material from authoritative textbooks (Rosen's Emergency Medicine, Braunwald's, Sabiston, Goldman-Cecil) to produce comprehensive, well-organized nursing student study notes. Let me compile the full response now.
Emergency Medical Cases: Comprehensive Nursing Study Notes
For Nursing Students | All Major Emergencies
Sources: Rosen's Emergency Medicine, Braunwald's Heart Disease, Sabiston Textbook of Surgery, Goldman-Cecil Medicine, Roberts & Hedges' Clinical Procedures in Emergency Medicine
HOW TO USE THESE NOTES
Each emergency follows the FMAN framework:
- F - First Aid / Pre-hospital
- M - Medical Management
- S - Surgical Management (where applicable)
- N - Nursing Management
PART 1: CARDIAC EMERGENCIES
1. CARDIAC ARREST
Pathophysiology
Abrupt loss of consciousness from inadequate cerebral blood flow due to failure of cardiac pump function. Electrical mechanisms:
- Asystole - 50% (worst prognosis)
- Ventricular Fibrillation (VF) / Pulseless VT - 20-25%
- Pulseless Electrical Activity (PEA) - 20-25%
- Mechanical causes: cardiac tamponade, ventricular rupture, acute flow obstruction
First Aid (Bystander / Pre-hospital)
- Call for help - activate EMS (call 999/112/911)
- Check responsiveness - tap shoulders, shout "Are you okay?"
- Look, listen, feel - no breathing or only gasping = cardiac arrest
- Begin CPR immediately:
- 30 compressions : 2 breaths (if trained)
- Compression-only CPR if untrained
- Rate: 100-120/minute
- Depth: at least 5 cm (2 inches) adults
- Allow full chest recoil
- Use AED as soon as available - follow voice prompts
Medical Management
| Shockable Rhythms (VF/pulseless VT) | Non-Shockable (Asystole/PEA) |
|---|
| Defibrillation - 120-200J biphasic | Continue CPR cycles |
| CPR 2 min between shocks | Find and treat reversible causes (4Hs & 4Ts) |
| Adrenaline (Epinephrine) 1mg IV every 3-5 min after 2nd shock | Adrenaline 1mg IV every 3-5 min immediately |
| Amiodarone 300mg IV after 3rd shock | No antiarrhythmics |
4 Hs and 4 Ts (Reversible Causes):
- Hypoxia, Hypovolaemia, Hypothermia, Hypo/Hyperkalemia
- Tension pneumothorax, Tamponade, Thrombosis (PE/MI), Toxins
Post-ROSC (Return of Spontaneous Circulation):
- Targeted Temperature Management (TTM): 32-36°C for 24 hours
- 12-lead ECG - look for STEMI (requires emergent PCI)
- IV fluids, vasopressors to maintain MAP >65 mmHg
- ICU admission, mechanical ventilation
Surgical Management
- Emergency PCI if post-arrest ECG shows STEMI
- Pericardiocentesis for tamponade
- Thoracotomy - for traumatic arrest (internal cardiac massage)
Nursing Management
- Maintain CPR quality - rotate compressors every 2 minutes
- Establish IV/IO access - large bore (antecubital or IO if IV fails)
- Prepare and administer medications per protocol
- Attach cardiac monitor and defibrillator pads
- Secure airway - assist with intubation, BVM ventilation
- Document arrest time, interventions, drug administration times
- Post-ROSC: monitor vitals every 15 min, neurological status (GCS)
- Family support - assign dedicated nurse for family communication
- Use GO-FAR score to guide shared decision-making in terminal patients
2. ACUTE MYOCARDIAL INFARCTION (AMI / Heart Attack)
Types
- STEMI - ST-Elevation MI (complete occlusion - immediate reperfusion)
- NSTEMI - Non-ST Elevation MI (partial occlusion)
- Unstable Angina - no enzyme rise, no ST changes
Classic Presentation
- Crushing/pressure chest pain, radiating to left arm, jaw, or back
- Diaphoresis, nausea/vomiting, dyspnea
- Feeling of "impending doom"
- Atypical (elderly, women, diabetics): epigastric pain, fatigue only, no chest pain
First Aid
- Sit patient down or semi-recumbent - do NOT lie flat if breathing difficulty
- Call EMS immediately
- Aspirin 300mg chewed (if not allergic, no contraindications)
- Loosen tight clothing
- Be ready to perform CPR if patient collapses
- Do not leave patient alone
Medical Management
MONA BASH mnemonic:
| Drug | Dose | Purpose |
|---|
| M - Morphine | 2-4mg IV titrated | Analgesia (use cautiously - may worsen outcomes in NSTEMI) |
| O - Oxygen | Only if SpO2 <94% | Avoid hyperoxia |
| N - Nitrates | GTN 0.4mg SL, or IV infusion | Vasodilation, pain relief |
| A - Aspirin | 300mg oral loading, then 75mg daily | Antiplatelet |
| B - Beta-blocker | Metoprolol 25-50mg oral | Reduce myocardial demand |
| A - ACE Inhibitor | Ramipril 2.5mg (start within 24h) | Reduce remodelling |
| S - Statin | Atorvastatin 80mg | Plaque stabilization |
| H - Heparin | LMWH (Enoxaparin) or UFH | Anticoagulation |
Additional for STEMI:
- P2Y12 inhibitor: Ticagrelor 180mg loading dose (preferred) or Clopidogrel 600mg

Nursing Management
- 12-lead ECG within 10 minutes of arrival - PRIORITY
- Continuous cardiac monitoring
- IV access x2 large bore
- Blood samples: Troponin I/T (x2, 3-6 hours apart), CK-MB, FBC, U&E, coagulation, lipids
- Administer medications as prescribed; document times
- Nil by mouth if going to PCI/surgery
- Monitor for complications: arrhythmias, heart failure (crackles, JVD, S3), cardiogenic shock
- Semi-recumbent positioning (30-45°)
- Reassure and reduce anxiety - pain scoring every 30 minutes
- Post-PCI: monitor puncture site (femoral or radial), neurovascular observations
- Educate patient: medications, lifestyle modification, cardiac rehab

- Fixed Rate Insulin Infusion (FRIII): 0.1 units/kg/hour (do NOT give stat bolus)
- Potassium replacement: Add KCl to fluid bags based on serum K+ levels (insulin drives K+ into cells - risk of hypokalaemia)
- Glucose: Add 10% dextrose when blood glucose <14 mmol/L (to prevent hypoglycaemia while continuing insulin)
- Treat precipitant: antibiotics for infection, manage MI
- Resolution criteria: pH >7.3, ketones <0.6 mmol/L, HCO3 >18
Nursing Management
- Hourly blood glucose and ketone monitoring
- Hourly urine output (catheterise if anuric or unconscious)
- 2-hourly U&E for potassium monitoring

- Fluid resuscitation (Parkland Formula): 4 mL x weight (kg) x %TBSA; give half in first 8 hours, half in next 16 hours (Hartmann's solution)
- Analgesia: IV morphine titrated to pain
- Wound care: Silver sulfadiazine or mafenide acetate; Mepitel/biobrane dressings
- Tetanus prophylaxis
- Prophylactic antibiotics: NOT routine; use only for confirmed infection
- Nutritional support: early enteral feeding (burns are hypermetabolic)
Surgical Management
- Escharotomy: for circumferential full-thickness burns (limb/chest compression)
- Excision and split-thickness skin grafting: standard for full-thickness burns
- Fasciotomy: for electrical burns with deep tissue damage
- Reconstructive surgery: for facial, hand, contracture burns
Nursing Management
- Fluid resuscitation monitoring: target urine output 0.5-1 mL/kg/hr (higher for electrical burns - 1-1.5 mL/kg/hr)
- Daily weight, strict fluid balance
- Wound dressing changes (aseptic technique, adequate analgesia before procedure)
- Monitor for inhalation injury: hoarse voice, carbonaceous sputum, singed nasal hairs, face burns - prepare for early intubation
- Nutritional assessment - liaise with dietitian (high-calorie, high-protein diet)
- Pressure garments for scar management
- Psychological support - burns cause severe body image disturbance
17. DROWNING / NEAR-DROWNING
First Aid
- Remove from water safely (do not enter without training)
- Call EMS
- Begin CPR immediately if not breathing - start with 5 rescue breaths
- Use AED when available
- Keep warm - all drowning victims are hypothermic
Medical Management
- Airway management: oxygen, early intubation if severe
- PEEP ventilation for pulmonary oedema / ARDS
- Treat hypothermia: active external rewarming (>30°C), cardiopulmonary bypass for severe hypothermia (<28°C)
- Chest X-ray, ABG, ECG
- "No one is dead until warm and dead" - continue CPR in hypothermic arrests until rewarming
Nursing Management
- Core temperature monitoring (rectal)
- Active rewarming: warm IV fluids, warm blankets, Bair Hugger
- Monitor for ARDS (worsening hypoxia 6-24 hours after event)
- Urine output monitoring
- Neurological monitoring (GCS)
PART 8: OBSTETRIC EMERGENCIES
18. ECLAMPSIA
Definition
New-onset tonic-clonic seizures in a woman with pre-eclampsia (BP >140/90 + proteinuria)
First Aid
- Call for help immediately
- Left lateral position (prevents aortocaval compression)
- Do not restrain
- Time seizure
- Protect airway
Medical Management
- Magnesium Sulphate: 4g IV loading dose over 5-10 min, then 1g/hour IV infusion
- If seizure recurs: 2g IV bolus
- Antidote for toxicity: Calcium Gluconate 10 mL of 10% IV
- Monitor for Mg toxicity: loss of patellar reflexes (first sign), respiratory depression
- Antihypertensives: Labetalol 20mg IV boluses or Hydralazine 5mg IV for BP >160/110
- Urinary catheter; fluid balance (restrict IV fluids - risk of pulmonary oedema)
- Deliver baby - definitive treatment
Surgical Management
- Caesarean section: if vaginal delivery not imminent after stabilisation
Nursing Management
- Left lateral position, padded cot sides
- Hourly urine output, aim >25 mL/hr
- Monitor reflexes and respiratory rate hourly (Mg toxicity signs)
- CTG (continuous fetal monitoring)
- Seizure precautions: suction, oxygen at bedside
- Fluid balance chart
- Post-partum: continue Mg for 24 hours after last seizure
PART 9: ABDOMINAL / GI EMERGENCIES
19. ACUTE ABDOMEN (General - includes Appendicitis, Perforation, Obstruction)
First Aid
- Do NOT give food or water (NBM - likely needs surgery)
- Lay patient in comfortable position (flexed knees reduces peritoneal pain)
- Call EMS
- Do NOT give strong analgesia before diagnosis (historical - now safe with opioids early)
Medical Management
- IV access, bloods: FBC, U&E, LFTs, amylase, CRP, lactate, group & save
- IV fluids: 0.9% NaCl or Hartmann's
- Analgesia: morphine IV (early adequate analgesia is humane and does not obscure diagnosis)
- Antibiotics: broad-spectrum if peritonitis/perforation (e.g., Piperacillin/Tazobactam)
- Antiemetics: Ondansetron 4mg IV
- NBM, nasogastric tube if vomiting or obstruction
Surgical Management
- Appendicitis: Laparoscopic appendicectomy (or conservative antibiotics in uncomplicated cases)
- Bowel perforation: Emergency laparotomy (Hartmann's procedure for perforated sigmoid)
- Bowel obstruction: NGT decompression; laparotomy if strangulation
- Ruptured AAA (Abdominal Aortic Aneurysm): Emergency EVAR or open repair - mortality >50% even with surgery
Nursing Management
- NBM, IV fluids, IV access
- Analgesia assessment (pain score 0-10 every hour)
- Monitor for peritonitis signs: rigidity, rebound tenderness (report to doctor)
- Urine output monitoring
- NGT insertion if obstruction/vomiting (attach to free drainage)
- Pre-operative preparation if surgery planned
- Post-operative: wound care, drain management, bowel function monitoring
20. UPPER GI BLEEDING (UGIB)
Causes
- Peptic ulcer disease (most common), oesophageal varices (cirrhosis), Mallory-Weiss tear, oesophagitis
Presentation
- Haematemesis (fresh red blood = active bleeding; coffee-ground = slower bleeding)
- Melaena (black, tarry stools)
- Haemodynamic instability in massive bleeds
Risk Scoring: Blatchford Score (pre-endoscopy), Rockall Score (post-endoscopy)
First Aid
- Lay patient flat or in recovery position if vomiting blood
- Call EMS
- Keep warm
Medical Management
| Intervention | Details |
|---|
| IV access | 2x large bore cannulas; bloods (FBC, coagulation, LFTs, group & crossmatch) |
| IV fluids | Resuscitate with 0.9% NaCl until blood products available |
| Blood transfusion | Target Hb >70 g/L (>80 if cardiovascular disease) |
| PPI | Pantoprazole 80mg IV bolus then 8mg/hour infusion (pre-endoscopy reduces need for intervention) |
| Terlipressin | 2mg IV for variceal haemorrhage (reduces portal pressure) |
| Antibiotics | Prophylactic IV antibiotics for variceal UGIB in cirrhosis (reduces bacterial infection mortality) |
| Urgent endoscopy | Within 24 hours (within 12 hours if high-risk); adrenaline injection + haemoclip/thermal coagulation |
| Sengstaken-Blakemore tube | Last resort for uncontrolled variceal bleeding (bridge to TIPSS) |
Nursing Management
- Lay flat or Trendelenburg; high-flow O2
- 2x large-bore IV cannulas; urgent bloods
- Activate massive haemorrhage protocol if needed
- Blood transfusion: verify patient identity, two-check procedure, monitor for transfusion reactions
- Monitor urine output (catheterise)
- Strict fluid balance
- Endoscopy preparation: informed consent, IV access, resuscitate before procedure
- Post-endoscopy: vital signs every 15 min, report any re-bleeding
