📄 Candidate Instructions

You are the Emergency Medicine doctor in a busy ED. Mr James Carter, 58 years old, has been brought in by ambulance with a 2-hour history of central chest pain.

He is currently haemodynamically stable. Observations: BP 148/92, HR 96, RR 16, SpO₂ 97% on air, Temp 37.1°C.

Please take a focused history from Mr Carter. You will be expected to explore the presenting complaint fully, relevant past medical history, medications, allergies, and social history relevant to this presentation. You have 8 minutes.

💡 Hints — What to cover ▼
  • Presenting complaint: SOCRATES — Site, Onset, Character, Radiation, Associated symptoms, Time course, Exacerbating/relieving factors, Severity.
  • Cardiac risk factors: Hypertension, diabetes, hypercholesterolaemia, smoking, family history of IHD, previous MI or angina.
  • Differentials to exclude: ACS, PE, aortic dissection, oesophageal rupture, pneumothorax, pericarditis.
  • Medications: Anticoagulants, antiplatelets, nitrates, antihypertensives, sildenafil (contraindication to nitrates).
  • Social: Recent travel (PE risk), occupation, home situation, smoking, alcohol.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are playing James Carter, a 58-year-old retired teacher. You are anxious but cooperative. You have been having crushing central chest pain for 2 hours, which started at rest while watching television.

🎭 Patient Script — Answers to give ▼
  • Pain: Central, crushing, "like an elephant on my chest." Started 2 hours ago at rest. Radiates to left arm and jaw. 8/10 severity. Not relieved by sitting forward (unlike pericarditis). No pleuritic component.
  • Associated: Sweating profusely, felt nauseated, mild shortness of breath. No haemoptysis, no cough, no fever.
  • PMH: Hypertension (amlodipine 10 mg), type 2 diabetes (metformin 1 g BD), high cholesterol (atorvastatin 40 mg). Had an angiogram 4 years ago — told "early disease." No previous MI.
  • Family history: Father died of a heart attack aged 62.
  • Social: Ex-smoker (20 pack-years, stopped 5 years ago), occasional alcohol, no recent travel, lives with wife.
  • Allergies: Penicillin — causes rash.
  • If asked about sildenafil/Viagra: "No, I don't take anything like that."
🔔 Examiner Cues ▼
  • If candidate has not asked about radiation after 2 minutes: Patient volunteers — "Oh, and it seems to go up into my jaw."
  • If candidate has not asked about risk factors by 4 minutes: "Should I mention my other medical problems?"
  • If candidate runs out of questions with time remaining: Patient says — "Is this serious, doctor? Am I having a heart attack?" — giving the candidate an opportunity to demonstrate communication.

📄 Candidate Instructions

You are the ED doctor. Mrs Priya Sharma, 34 years old, has been brought in after a witnessed collapse in the supermarket. A bystander performed CPR briefly before she regained consciousness spontaneously.

She is now alert and orientated. Observations: BP 110/70, HR 88 regular, SpO₂ 99%, RR 14.

Please take a focused history from the patient to determine the most likely cause of her collapse. You have 8 minutes.

💡 Key areas to cover ▼
  • Pre-syncopal symptoms: Prodrome (palpitations → arrhythmia; nausea/lightheadedness → vasovagal; no warning → cardiac).
  • The event itself: Witnessed account, duration of LOC, jerking movements, incontinence, tongue biting (seizure vs syncope).
  • Post-event: Rapid recovery (vasovagal/cardiac) vs prolonged confusion (seizure/postictal).
  • Triggers: Standing, pain/emotion, exercise (worrying — suggests HOCM, LQTS), hot environment.
  • Cardiac history: Previous syncope, family history of sudden cardiac death, known arrhythmia, structural heart disease.
  • Medications: QT-prolonging drugs, diuretics, antihypertensives.
  • Gynaecological: LMP, possibility of pregnancy (ectopic can cause collapse).

⚠️ Examiner Instructions — Not for Candidate

You are Priya Sharma, 34, a nurse. You are shaken but cooperative. This was a vasovagal syncope in the context of not eating and standing in a hot queue for 20 minutes. There is no sinister aetiology but the candidate should systematically exclude dangerous causes.

🎭 Patient Script ▼
  • Before collapse: Felt warm, nauseated, vision went grey, legs felt like jelly. Had been standing for 20 minutes in a hot supermarket queue. Had skipped breakfast.
  • No palpitations, no chest pain, no preceding headache.

📄 Candidate Instructions

You are the ED senior doctor. Mr David Singh, 54, was brought to ED after a seizure. A CT head has been performed urgently and has shown a large right temporal mass with surrounding oedema, highly suspicious for a primary brain tumour.

Neurosurgery has been consulted and confirmed this is almost certainly a high-grade glioma. Mr Singh has recovered from his seizure and is with his wife. He is asking to speak to the doctor to find out what the scan showed.

Please have this conversation with the patient. You are not expected to give a definitive prognosis, but you should explain the finding honestly and sensitively.

💡 SPIKES Framework Reminder ▼
  • S — Setting: Private, appropriate environment. Sit down. Turn off bleeps if possible.
  • P — Perception: "What do you already know / what were you expecting?" Find out their baseline understanding.
  • I — Invitation: "Are you happy for me to tell you what we found, and would you like your wife to be here?"
  • K — Knowledge: Fire a warning shot — "I'm afraid I have some difficult news." Then deliver clearly without jargon — "The scan has shown an abnormal growth in the brain."
  • E — Emotions / Empathy: Allow silence. Acknowledge the emotion — "I can see this is very hard to hear." Do not rush to fill silence with information.
  • S — Strategy / Summary: What happens next. Neurosurgery referral, MDT, biopsy. Written information. Who to call. Follow-up plan.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are playing David Singh. Start calm and slightly anxious. When told about the mass, become visibly distressed and ask "Is it cancer? Am I going to die?" Allow appropriate silences. If the candidate tries to give a definitive prognosis, push back with "But roughly, how long do I have?" — observe how the candidate handles uncertainty.

🎭 Role-player Script & Cues ▼
  • Opening: "Doctor, please just tell me straight — what did you find on the scan? I've been lying here for hours worrying."
  • After bad news delivered: Silence, then tears. "This can't be right. I have two kids. They're only 12 and 15."
  • Question 1: "Is it cancer?"
  • Question 2: "How long have I got?"
  • Question 3: "Can they operate? Can they cure it?"
  • If candidate is too clinical or uses jargon: "I don't understand what you mean — can you explain that?"
  • If candidate handled well — express thanks. If rushed — express feeling like they weren't listened to.

📄 Candidate Instructions

You are the ED registrar. Mrs Angela Thompson is waiting to speak to you. Her 78-year-old mother was brought to ED 6 hours ago with confusion. She has been in a cubicle for 4 hours without anyone coming to explain what is happening.

Mrs Thompson is visibly angry in the corridor and has told the nurse she "wants to make a formal complaint." The nurse has asked you to speak to her.

The patient (her mother) has a UTI — bloods and urine are back, antibiotics have been started. She is currently stable.

Please speak to Mrs Thompson and manage this situation professionally.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Angela Thompson. Start very angry and confrontational. Begin with: "Finally! I've been waiting for hours. This is absolutely disgraceful — my mother is elderly and confused and nobody has come to see us. I want to make a complaint right now." Gradually de-escalate if the candidate is empathic, listens well and apologises appropriately without being defensive. Remain angry if candidate is defensive, dismissive or makes excuses.

🎭 Escalation / De-escalation Guide ▼
  • If candidate apologises sincerely without defensiveness: Soften slightly. Ask about mother's condition.
  • If candidate explains delay with excuses ("we're very busy"): Escalate — "I don't care how busy you are, she's my mother."
  • If candidate uses medical jargon: "Can you please speak in plain English?"
  • Key question to ask: "So what's actually wrong with her and what are you doing about it?"
  • If candidate handles well: End with "Thank you for explaining. I'm still not happy with the wait but I appreciate you taking the time."
  • Do not accept apology if candidate never acknowledges the legitimate concern about the wait.

📄 Candidate Instructions

You are the ED doctor. A 61-year-old man presents with severe central chest pain for 45 minutes. The examiner will describe the ECG findings to you.

Please systematically interpret the ECG using a structured approach, state your diagnosis, and outline your immediate management plan. You will also be asked two further questions about this ECG.

❤️ Structured ECG Interpretation Approach ▼
  • 1. Rate: Count R-R intervals (300/large squares or 1500/small squares). Normal 60–100.
  • 2. Rhythm: Regular/irregular, P before every QRS, QRS after every P.
  • 3. Axis: Lead I and aVF — both positive = normal axis. Lead I positive, aVF negative = LAD. Lead I negative = RAD.
  • 4. P waves: Present, morphology (bifid = P-mitrale, peaked = P-pulmonale), PR interval (normal 120–200 ms).
  • 5. QRS complex: Duration (normal <120 ms), morphology, Q waves (pathological = >1 mm wide, >2 mm deep, or >25% of R wave).
  • 6. ST segment: Elevation (>1 mm limb leads, >2 mm chest leads) or depression. Morphology (concave/convex/saddle).
  • 7. T waves: Inversion, hyperacute, tall tented (hyperkalaemia).
  • 8. QTc: Normal <440 ms males, <460 ms females (Bazett formula).
  • 9. Diagnosis + territory: Inferior (II, III, aVF), Anterior (V1–V4), Lateral (I, aVL, V5–V6), Posterior (tall R V1–V2 with ST depression).

⚠️ Examiner Instructions

Read the following ECG description to the candidate when they are ready to interpret. Then ask the two follow-up questions at the end.

📋 ECG Description & Follow-up Questions ▼
  • ECG description to read aloud: "Rate 98 bpm, regular rhythm. Normal axis. P waves present, PR interval 160 ms. QRS duration 90 ms. Pathological Q waves present in leads II, III and aVF. ST elevation of 3 mm in leads II, III and aVF. Reciprocal ST depression in leads I and aVL. T waves upright in lateral leads. No other significant findings."
  • Follow-up Question 1: "What artery is most likely occluded and what is the immediate management?" — Expected: Right coronary artery (RCA). Activate cath lab (PPCI), dual antiplatelet therapy (aspirin 300 mg + ticagrelor 180 mg), anticoagulation (heparin or fondaparinux), morphine/GTN for pain, oxygen only if SpO₂ <94%, target door-to-balloon time <90 minutes.
  • Follow-up Question 2: "What complication should you be most vigilant for in inferior MI?" — Expected: Right ventricular infarction (especially with ST elevation in V4R), complete heart block, bradyarrhythmias (AV node supplied by RCA in 85%), hypotension — avoid nitrates and diuretics (preload dependent). Also: VF, papillary muscle rupture causing acute MR.

📄 Candidate Instructions

A 72-year-old man with known COPD is brought to ED by ambulance acutely breathless. He is on 10L O₂ via non-rebreathe mask which was applied by the paramedics. GCS 14/15 (slightly confused). RR 28.

The examiner will give you his ABG results. Please interpret them systematically, state your diagnosis and immediate management plan.

🔬 ABG Interpretation Framework ▼
  • 1. pH: Normal 7.35–7.45. <7.35 = acidosis. >7.45 = alkalosis.
  • 2. PaCO₂: Normal 4.5–6.0 kPa. ↑ = respiratory acidosis / metabolic alkalosis compensation. ↓ = respiratory alkalosis / metabolic acidosis compensation.
  • 3. HCO₃: Normal 22–26 mmol/L. ↑ = metabolic alkalosis / chronic respiratory compensation. ↓ = metabolic acidosis / chronic respiratory alkalosis compensation.
  • 4. PaO₂: Normal >10 kPa on air. Interpret in context of FiO₂ (A-a gradient).
  • 5. Compensation: Is there appropriate compensation? Metabolic compensation takes hours–days. Respiratory compensation takes minutes.
  • 6. Lactate: Normal <2 mmol/L. Elevated = tissue hypoperfusion, sepsis, liver failure, metformin.
  • 7. Type I vs Type II RF: Type I = PaO₂ <8 kPa, PaCO₂ normal/low. Type II = PaO₂ <8 kPa, PaCO₂ >6 kPa.

⚠️ Examiner Instructions

Read ABG results aloud. Ask follow-up questions. Key teaching point: candidate must identify that 10L O₂ is harmful in this COPD patient and must immediately wean oxygen.

📋 ABG Values & Follow-up Questions ▼
  • ABG values to read aloud: "pH 7.28, PaCO₂ 9.2 kPa, PaO₂ 14.8 kPa, HCO₃ 34 mmol/L, BE +8, Lactate 1.4 mmol/L, SpO₂ 99%, FiO₂ 0.6 (10L NRB mask), glucose 6.2."
  • Question 1: "What is your interpretation and what is the most urgent action?" — Expected: Respiratory acidosis (↓pH, ↑CO₂) with metabolic compensation (↑HCO₃ — chronic change). Type II respiratory failure. Despite acceptable SpO₂, excessive oxygen is suppressing hypoxic drive → CO₂ retention. Immediately reduce O₂ to 24–28% Venturi mask, target SpO₂ 88–92% in known COPD. Consider NIV (BIPAP) if pH <7.35 with CO₂ retention despite controlled O₂.
  • Question 2: "What are the criteria for initiating NIV in this patient?" — Expected: GOLD/BTS criteria: pH 7.25–7.35, PaCO₂ >6 kPa, clinically appropriate, reversible cause, patient able to protect airway. This patient qualifies (pH 7.28). NIV: BIPAP, start IPAP 10–15, EPAP 4–5, titrate. Reassess ABG after 1 hour. If no improvement — consider ITU/intubation discussion.
CriterionMarks
Systematic ABG Interpretation
Correctly identifies acidosis (pH 7.28)1
Identifies primary respiratory acidosis (↑PaCO₂ 9.2 kPa)2
Identifies metabolic compensation (↑HCO₃ 34 = chronic)2
Notes PaO₂ is paradoxically normal/high due to supplemental O₂1
Lactate normal — no evidence of tissue hypoperfusion1
Diagnosis
Correct diagnosis — Type II respiratory failure, acute-on-chronic respiratory acidosis in COPD2
Immediate Management
Immediately identifies danger of high-flow O₂ and reduces to Venturi 24–28%3
Target SpO₂ 88–92% in COPD stated1
Considers / initiates NIV — states BIPAP with starting pressures2
States criteria for NIV correctly — pH 7.25–7.35 with CO₂ retention1
Plans repeat ABG in 1 hour to assess response1
