📄 Candidate Instructions

You are the ED doctor. Mr Ewan McBride, 44 years old, presents with a 3-day history of worsening low back pain. He has had back pain before but says this episode feels different. He is a builder and lifts heavy loads regularly.

Obs: BP 132/80, HR 78, apyrexial, GCS 15.

Please take a focused history. You have 8 minutes.

💡 Key areas — Red Flags & Cauda Equina ▼
  • Pain characterisation: SOCRATES. Site, radiation (sciatic distribution — below knee?), onset, character (constant vs positional), severity, aggravating/relieving factors.
  • Cauda equina symptoms — MUST ask all:
    • Bladder — urinary retention (inability to void, overflow incontinence) or incontinence
    • Bowel — faecal incontinence or constipation (new)
    • Saddle anaesthesia — numbness/altered sensation in perineum, inner thighs, genitalia
    • Bilateral leg weakness
    • Sexual dysfunction (new)
  • Other red flags (TUNA FISH mnemonic): Trauma, Under 20 / Over 50 (first episode), Neurological deficit, Anticoagulants/steroids, Fever/infection, Intravenous drug use, Systemically unwell / weight loss / cancer history.
  • Cancer screen: Previous malignancy, unexplained weight loss, night sweats, bone pain elsewhere (metastatic disease).
  • Infection screen: Fever, recent dental work, IV drug use (discitis/epidural abscess).
  • PMH: Previous back surgery, osteoporosis (vertebral fracture), steroid use.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Ewan McBride. You have cauda equina syndrome. You have not volunteered the bladder symptoms because you are embarrassed. Only disclose if directly and specifically asked. You noticed you couldn't fully empty your bladder yesterday and had a brief episode of leaking. You also have numbness "down below" which you didn't think was related.

🎭 Patient Script ▼
  • Pain: Central low back, radiating down both legs to the calves. Constant, 7/10. Worse on sitting, some relief lying flat. Started after heavy lift 3 days ago.
  • Bladder (only if directly asked): "Actually yes — I've been struggling to pass water. Had to really strain yesterday. And I've had a couple of leaks." Urinary retention with overflow.
  • Saddle anaesthesia (only if directly asked): "Now you mention it, I've felt numb down there for about 24 hours — thought it was just the pain."
  • Bowel: Not opened bowels for 2 days (constipation). No frank incontinence.
  • Bilateral leg weakness: Legs feel heavy going upstairs today.
  • No fever, no weight loss, no cancer history, no steroids, no IVDU. No previous back surgery.
🔔 Examiner Cues ▼
  • If candidate does not specifically ask about bladder by 4 minutes: do NOT volunteer. Prompt candidate: "Is there anything else you'd like to ask Mr McBride?"
  • At the end, ask: "What is your diagnosis and immediate management plan?"
  • Expected: Cauda equina syndrome — emergency MRI spine, urgent neurosurgical referral, catheterise if retention confirmed, do not discharge.

📄 Candidate Instructions

You are the ED doctor. Mrs Amira Hassan, 29 years old, is 32 weeks pregnant and has arrived by ambulance with a 30-minute history of painless bright red vaginal bleeding. She is conscious and distressed.

Obs: BP 96/58, HR 128, RR 22, SpO₂ 98%, Temp 36.9°C.

Please take a focused obstetric history. You have 8 minutes. Do NOT perform a vaginal examination.

💡 Key areas — APH Differentials ▼
  • Bleeding characterisation: Onset, amount (pads soaked?), colour, clots, associated pain (placental abruption = painful; placenta praevia = painless), precipitating factor (trauma, intercourse).
  • APH differentials:
    • Placenta praevia: Painless, bright red, can be recurrent, low-lying placenta on USS.
    • Placental abruption: Painful (constant uterine pain), dark blood, uterus woody/tender, fetal distress. Associated with hypertension, cocaine, trauma.
    • Vasa praevia: Ruptured membranes + fetal blood — rare, fetal HR drops immediately.
    • Show / local causes: Cervical ectropion, infection.
  • Current pregnancy: Gestation (32/40), singleton/multiple, known placenta praevia on scan, rhesus status (anti-D needed if Rh-negative), antenatal care (booked?), complications this pregnancy.
  • Fetal movement: Has she felt the baby move today? Reduced movement = fetal compromise.
  • Contractions: Any regular tightening (preterm labour)?
  • Obstetric history: Parity, previous CS (scar dehiscence risk), previous APH, IUGR.
  • Medical: Pre-eclampsia, hypertension, diabetes, blood disorders (thrombocytopenia).

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Amira Hassan. You are frightened and tearful. This is placenta praevia — painless bright red bleeding, known low-lying placenta on 20-week scan (she will tell this if asked about scan findings). She is Rhesus negative. She has felt reduced fetal movement today. No contractions.

🎭 Patient Script ▼
  • Bleeding: "It just started — no warning. Bright red blood. I've soaked two pads in the last 30 minutes. No pain at all." No clots. No trauma. No recent intercourse.
  • Scan: "They said at my 20-week scan that my placenta was low down — they wanted to rescan at 32 weeks. That's this week."
  • Fetal movement: "I haven't felt him move much since this morning — that's not like him."
  • Contractions: None.
  • Blood group: If asked — "I think I'm Rh negative — it's in my notes."
  • Obstetric history: G2P1 — first baby was vaginal delivery, uncomplicated. No previous APH. No previous CS.
  • PMH: Nil. No medications. NKDA.

A 68-year-old man with known AF (not anticoagulated) presents with sudden onset severe pain in his right leg 3 hours ago. The leg looks pale and he says it feels numb.

Please perform a focused lower limb vascular examination. The examiner will provide findings. Present your diagnosis and immediate management.

🔑 The 6 Ps of Acute Limb Ischaemia ▼
  • 6 Ps: Pain, Pallor, Pulselessness, Paraesthesia, Paralysis, Perishing cold (Poikilothermia).
  • Examination sequence:
    • Inspect both legs — colour (pallor, mottling, cyanosis), muscle wasting, ulcers, hair loss, nail changes
    • Temperature — compare sides with dorsum of hand
    • Capillary refill — both feet centrally and peripherally
    • Sensation — light touch and pinprick bilaterally
    • Power — dorsiflexion and plantarflexion bilaterally
    • Pulses — femoral, popliteal (knee flexed), posterior tibial, dorsalis pedis — both sides. Graded 0, 1, 2+
    • Buerger's test — elevate leg to 45° (pallor = arterial insufficiency), then dependent (reactive hyperaemia — Buerger's angle)
    • Auscultation — femoral bruits, aortic bruit
  • Rutherford classification: I — viable; IIa — threatened, salvageable; IIb — immediately threatened; III — irreversible (paralysis + anaesthesia + mottling).
  • Management: IV heparin immediately, urgent vascular surgery referral, Doppler ankle-brachial pressure index, angiography, surgical embolectomy or thrombolysis. Time critical — irreversible after 6 hours typically.

⚠️ Examiner Instructions — Not for Candidate

Findings represent right acute limb ischaemia (Rutherford IIb — immediately threatened). Feed findings as candidate examines. Critical point: immediate heparin and vascular surgery — this is a surgical emergency.

📋 Findings to Feed ▼
  • Inspection: Right leg pale, mottled below knee. Left leg normal colour. No ulcers or hair loss (acute, not chronic).
  • Temperature: Right foot and calf markedly cold. Left warm.
  • CRT: Right foot >5 seconds. Left 2 seconds.
  • Sensation: Reduced light touch and pinprick right foot and lower leg.
  • Power: Weakened dorsiflexion right foot (4/5). Left normal.

📄 Candidate Instructions

A 74-year-old man with benign prostatic hypertrophy presents in acute urinary retention. He has not passed urine for 12 hours and has a palpable, tender bladder to the umbilicus. Bladder scan confirms 900 mL.

Please demonstrate male urethral catheterisation on this manikin. Talk through each step. State the catheter type, size and how you confirm correct placement.

📝 Equipment & Key Steps ▼
  • Catheter choice: 12–16 Fr Foley catheter (standard retention). Tiemann-tip/coude catheter if prostatic obstruction and standard fails. Silicone if latex allergy or long-term use.
  • Equipment: Catheterisation pack, sterile gloves, drape, aqueous chlorhexidine or saline, 10 mL lidocaine gel (instillagel — wait 3–5 mins), 10 mL sterile water for balloon, drainage bag.
  • Steps:
    1. Confirm indication, consent, check allergy (latex/lidocaine)
    2. Position supine, expose genitalia
    3. Wash hands, full aseptic technique — sterile gloves, drape, clean pack
    4. Retract foreskin (if present), clean glans and meatus with chlorhexidine/saline — 3 swabs, front to back, each used once
    5. Insert instillagel (10 mL) into urethra — wait 3–5 min
    6. Hold penis at 90° (perpendicular to body) to straighten prostatic urethra
    7. Advance catheter to the hilt (bifurcation) before inflating balloon
    8. Inflate balloon with 10 mL sterile water only when urine flows freely
    9. Retract gently until resistance felt
    10. Replace foreskin (prevent paraphimosis!)
    11. Connect to drainage bag, document volume, urine sample sent
  • Complications: Urethral trauma (false passage), UTI, haematuria, paraphimosis (forgot foreskin), balloon inflation in urethra (if inflated before hilt → trauma).
  • If resistance met: Do not force. Try Tiemann catheter. Urology referral for flexible cystoscopy-guided catheterisation or suprapubic catheter.

⚠️ Examiner Instructions — Not for Candidate

Critical safety checks: (1) does candidate advance to the hilt before inflating balloon? (2) does candidate replace the foreskin? Ask mid-procedure: "You're advancing the catheter and feel resistance — what do you do?"

📄 Candidate Instructions

A 35-year-old man presents with a 4 cm laceration to his right forearm following a fall onto broken glass 2 hours ago. He is otherwise well. You have assessed that the wound is clean, does not involve tendon or bone, and is suitable for primary closure.

Please demonstrate wound assessment and interrupted suturing technique on the manikin. Talk through each step including anaesthesia, cleaning, closure choice and aftercare.

📝 Wound Assessment & Suturing ▼
  • Wound assessment: Mechanism (clean vs contaminated vs bite), time since injury (>6 hours = higher infection risk — may leave open or delayed primary closure), depth (skin only vs deep structures), neurovascular status distally, foreign body risk (glass → XR).
  • Contraindications to primary closure: Bite wounds (high infection risk — delayed closure or leave open), heavily contaminated, >12 hours old in general (face can be sutured up to 24 hours), signs of infection.
  • Anaesthesia: 1% lidocaine (max 3 mg/kg; with adrenaline 7 mg/kg). Field block or infiltrate wound edges. Aspirate before injecting. Warn of sting. Lidocaine with adrenaline — avoid fingers/toes/nose/penis (end arteries).
  • Cleaning: Irrigate with 500+ mL saline under pressure (20 mL syringe). Remove visible foreign bodies. Debride devitalised tissue.
  • Closure options: Sutures (best cosmesis, deep wounds), staples (scalp, trunk), tissue adhesive/glue (superficial, low-tension wounds), steri-strips (very superficial).
  • Suture technique (interrupted): Non-dominant hand holds forceps — pick up skin edge (not crush). Needle enters skin at 90°, passes through both edges, exits symmetrically. Knot tied: instrument tie — 2 throws one way, 1 throw back. Knot to side. 3–5 mm bite, 5 mm spacing. Evert wound edges.
  • Suture material: Monofilament non-absorbable (Prolene/nylon) for skin. Absorbable (Vicryl) for deep layers. Size: 3/0 trunk/limb, 4/0 face/hand, 2/0 scalp.
  • Aftercare: Tetanus status. Antibiotics if contaminated/bite. Wound care instructions. Removal: face 5 days, scalp/limb 7–10 days, back/sole 10–14 days.

⚠️ Examiner Instructions — Not for Candidate

Assess LA technique (aspirate, correct dose, no end arteries), wound irrigation, suture technique (eversion, 90° needle, knot technique), and aftercare including tetanus. Ask: "Is this a bite wound — would you manage it differently?" (Yes — leave open or delayed primary closure.)

📄 Candidate Instructions

You are the ED registrar. Mr Patrick Walsh, 66, presented to your ED last week with chest pain. He was assessed and discharged with a diagnosis of musculoskeletal pain. He has now been re-admitted by his GP — troponins taken at his GP today show a markedly elevated result, and his ECG shows established Q waves. He had an NSTEMI that was missed.

He is now haemodynamically stable. You have been asked to speak to him. He doesn't yet know the diagnosis was missed.

Please speak to Mr Walsh, disclose what happened, and manage this conversation in accordance with your duty of candour. You have 8 minutes.

💡 Duty of Candour Framework ▼
  • Duty of Candour (CQC/GMC): Legal and professional duty to be open and honest with patients when things go wrong. Must tell patient when something has gone wrong, apologise, explain what happened, explain what can be done to put it right.
  • Key elements:
    1. Acknowledge what happened honestly
    2. Apologise sincerely — "I am sorry" (not "I'm sorry you feel that way")
    3. Explain clearly and without jargon what happened and why
    4. Explain impact — he had a heart attack that was not diagnosed at first visit
    5. Describe what is being done now and what treatment he needs
    6. Explain what will be done to investigate and prevent recurrence (incident review, SI report)
    7. Offer written summary
    8. Do not blame individuals — institutional accountability
    9. Advise about formal complaint process — PALS
  • Pitfalls to avoid: Being defensive, minimising the error, excessive medical jargon, promising things you cannot guarantee, blaming colleagues.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Patrick Walsh. Start calm but confused. When told the diagnosis was missed, become upset and angry. "I told them it was my heart. I said to the doctor — are you sure? And they said it was just muscular." If candidate apologises sincerely and is open, soften. If defensive or uses jargon, escalate: "So what you're telling me is your department nearly killed me?"

CriterionMarks
Setting & Opening
Private setting, sits down, has support person for patient if possible1
Introduces self and role — explains purpose of conversation clearly1
Disclosure
Discloses error clearly and honestly — does not minimise or use euphemisms3
Explains in plain language — "the tests we did last week missed a heart attack"2
Sincere apology — "I am sorry this happened" — not defensive or conditional2
Current Situation & Next Steps
Explains current diagnosis and what treatment he now needs2
Explains steps being taken — internal review, incident report, preventing recurrence2
Offers written summary of conversation1
Handling Anger & Complaints
Remains calm, does not become defensive when patient is angry2
Does not blame individual colleagues — institutional accountability1
Informs patient of formal complaints process — PALS1
Allows patient to express feelings — does not rush or fill silence1

📄 Candidate Instructions

You are an ED registrar. A nurse, Sarah, has pulled you aside during the shift. She tells you she is worried about your consultant, Dr Collins. She says she can smell alcohol on his breath, he has made two prescribing errors today that she has corrected, and he seems confused and unsteady on his feet. This is a busy Saturday evening shift.

Please speak to Sarah and manage this situation appropriately. You have 8 minutes.

💡 Framework — GMC Raising Concerns ▼
  • Patient safety is the priority. A doctor who is unfit to practise must be removed from clinical care immediately.
  • Immediate steps:
    1. Thank the nurse — take concern seriously, do not dismiss
    2. Clarify what has been observed — specific incidents, behaviours
    3. Assess immediate patient safety — are current patients safe?
    4. Escalate immediately — contact senior colleague (clinical director, on-call consultant, medical director)
    5. Dr Collins should be removed from clinical care — not confronted aggressively, done discreetly and respectfully
    6. Document concerns factually
  • GMC Good Medical Practice: All doctors have a duty to act if a colleague may be putting patients at risk. "You must protect patients from risk of harm posed by another doctor's conduct, performance or health."
  • Do not: Ignore the concern, cover it up, confront the doctor publicly, try to manage alone without escalating.
  • Support for colleague: Once patient safety is secured — colleague needs support. Occupational health, GP, Practitioner Health Programme (anonymous NHS support for doctors with health problems).
  • Confidentiality: Patient safety overrides professional loyalty. This is a formal raising-of-concerns situation, not a personal issue.

⚠️ Examiner / Role-player Instructions (as Sarah the nurse) — Not for Candidate

You are worried and hesitant — "I don't want to get him in trouble, he's usually a lovely doctor." Test whether candidate takes the concern seriously, protects patients as primary concern, and escalates rather than trying to manage it alone. If candidate says "I'll just have a quiet word with him" — push: "But what if he carries on working? There are patients waiting to be seen."

CriterionMarks
Initial Response

A 23-year-old woman is brought in by ambulance following a deliberate overdose of her grandmother's amitriptyline tablets. She took approximately 20 × 25mg tablets (500mg total) one hour ago. She is currently drowsy, GCS 10, with a HR of 136 and BP of 86/50.

The examiner will give you her ECG and blood results. Please interpret them systematically, state your diagnosis of the toxidrome, and outline immediate management.

💡 TCA Toxidrome & Management ▼
  • TCA toxidrome (anticholinergic + sodium channel blocking + α-blocking):
    • Anticholinergic: dry mouth, urinary retention, ileus, mydriasis, hyperthermia, flushing, delirium ("mad as a hatter, dry as a bone...")
    • Na channel blocking: wide QRS (>100ms = significant, >160ms = high VF risk), terminal R wave in aVR >3mm, right axis deviation
    • α-blocking: hypotension
    • CNS: drowsiness → seizures → coma
  • ECG hallmarks of TCA toxicity: Sinus tachycardia, widened QRS, prolonged QTc, terminal R in aVR, right axis deviation, Brugada-like pattern.
  • Management:
    1. ABCDE — airway (early intubation if GCS deteriorating)
    2. Sodium bicarbonate 1–2 mmol/kg IV — narrows QRS, raises pH, treats hypotension. Repeat until QRS <100ms or pH 7.50–7.55. Aim alkalosis.
    3. IV fluids for hypotension. Vasopressors if refractory (noradrenaline).
    4. Seizures — benzodiazepines first line. Avoid phenytoin (sodium channel blocker — worsens TCA toxicity)
    5. Avoid physostigmine (seizures risk), flumazenil (lowers seizure threshold)
    6. Activated charcoal only if within 1 hour and airway protected
    7. Lipid emulsion rescue therapy if refractory cardiac toxicity
    8. Continuous monitoring — telemetry, ITU

⚠️ Examiner Instructions — Not for Candidate

Read the ECG description and bloods aloud. Key assessment: does candidate give sodium bicarbonate as first-line treatment? Ask: "The QRS is now 140ms and she has just had a generalised seizure — what do you give?"

📋 Results to Read Aloud ▼

ECG: Sinus tachycardia 136 bpm. QRS duration 118ms (widened). Terminal R wave in aVR 4mm. QTc 520ms. Right axis deviation. No ST elevation.

Bloods: pH 7.28, HCO₃ 14 (metabolic acidosis), Na 138, K 3.1, Glucose 6.8, Paracetamol level undetectable, Salicylate undetectable. ECG is the key investigation here.

Follow-up Q1: "What is the most important immediate treatment?"

Expected: IV sodium bicarbonate 1–2 mmol/kg — directly addresses QRS widening, hypotension, and metabolic acidosis. Target serum pH 7.50–7.55.

Follow-up Q2: "She seizes — what do you give and what do you avoid?"

Expected: IV benzodiazepine (lorazepam/diazepam). Avoid phenytoin — sodium channel blocker, worsens TCA toxicity. Avoid flumazenil.

📄 Candidate Instructions

A 4-year-old boy, Noah, is brought in by ambulance. He has been unwell for 8 hours with high fever, vomiting, and is now difficult to rouse. His mother noticed a rash on his legs 2 hours ago. On arrival he is obtunded (GCS 9), mottled, with a purpuric non-blanching rash on his legs and trunk.

Obs: HR 178, BP 62/38, RR 44, Temp 39.8°C, SpO₂ 91% on air, CRT 6 seconds centrally.

The examiner will read you his bloods. Interpret them, confirm your diagnosis, and give a time-critical management plan.

💡 Meningococcal Sepsis — Key Points ▼
  • Clinical diagnosis: Non-blanching purpuric rash + septic shock = meningococcal septicaemia until proven otherwise. DO NOT wait for blood results to treat.
  • Paediatric Sepsis Six (within 1 hour):
    1. High-flow oxygen
    2. Blood cultures (before antibiotics if possible — do NOT delay for this)
    3. IV/IO antibiotics — ceftriaxone 80 mg/kg IV (max 4g) or cefotaxime
    4. IV/IO fluid bolus — 10 ml/kg 0.9% NaCl, reassess, repeat up to 40 ml/kg
    5. Check glucose and lactate
    6. Consider ICU/PICU referral
  • DIC features: Prolonged PT/APTT, low fibrinogen, elevated D-dimer, low platelets, fragmented RBCs.
  • Meningitis vs septicaemia: Septicaemia without meningism — do NOT do LP until stabilised. LP contraindicated with coagulopathy, raised ICP, haemodynamic instability.
  • Steroids: Dexamethasone 0.15 mg/kg QDS — for suspected bacterial meningitis (not pure septicaemia). Give before or with first dose of antibiotics.
  • Public health: Notifiable disease. Contact prophylaxis — ciprofloxacin or rifampicin for close contacts within 24 hours.

⚠️ Examiner Instructions — Not for Candidate

Read results aloud. Critical assessment: does candidate give antibiotics immediately without waiting for full results? Ask: "A junior doctor says we should wait for LP before giving antibiotics — what do you say?"

📋 Results to Read Aloud ▼

WBC 2.1 (↓↓ — consumption), Neutrophils 1.4, Platelets 42 (↓↓), Hb 96 (↓), CRP 284, PCT 88, Lactate 8.2 (↑↑), Glucose 2.1 (↓ — hypoglycaemia), Na 128, K 5.8, Creatinine 142 (↑ — AKI), PT 32s (↑), APTT 68s (↑), Fibrinogen 0.6 g/L (↓↓ — DIC), D-dimer >20, pH 7.08, HCO₃ 8, Base excess −18.

Follow-up Q1: "LP — yes or no right now?"

Expected: NO. Contraindicated — coagulopathy (DIC), haemodynamic instability, likely raised ICP. Do NOT delay antibiotics for LP. Treat first.

Follow-up Q2: "Blood glucose is 2.1 — what do you give and how?"

Expected: 2 ml/kg 10% dextrose IV/IO (not 50% dextrose in children). Recheck glucose 15 minutes later.
