📄 Candidate Instructions

You are the ED doctor. Mrs Fatima Malik has brought her 18-month-old son Aiden to the ED. He has been unwell for 2 days with a high temperature. She is visibly worried.

Triage obs: Temp 39.4°C, HR 168, RR 44, SpO₂ 96% on air, capillary refill 2 sec centrally.

Please take a focused history from the parent. You have 8 minutes.

💡 Key areas — NICE Traffic Light / NICE Feverish Illness ▼
  • Fever: Duration, height, pattern, response to antipyretics, rigors.
  • NICE red flags — meningococcal/serious bacterial infection: Non-blanching rash, bulging fontanelle, neck stiffness, photophobia, high-pitched unusual cry, prolonged seizure, continuous crying, reduced consciousness.
  • Source of infection screen: URTI (cough, runny nose, ear pulling, sore throat), LRTI (cough, wheeze, grunting, nasal flaring), UTI (wet nappies, crying on micturition, offensive urine, secondary bedwetting in older child), GI (vomiting, diarrhoea), rash, joint swelling.
  • Hydration status: Wet nappies (frequency, last one), oral intake, tears, fontanelle (sunken vs bulging), activity level.
  • Immunisation history: Up to date? Any recent vaccines?
  • Travel history: Malaria endemic area, TB contacts.
  • PMH/birth history: Premature, congenital heart disease, immunodeficiency, previous hospitalisations, medications.
  • Social: Childcare/nursery contacts, siblings, parental concern level (important).

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Mrs Fatima Malik, Aiden's mother. You are anxious and tearful. The working diagnosis is UTI with early sepsis. No meningococcal features. He has had very few wet nappies today (2 in 12 hours, normally 6). He is less playful than normal and not feeding well.

🎭 Parent Script ▼
  • Fever: Started 2 days ago. Up to 39.8 at home. Gave Calpol — "brought it down a bit but it keeps coming back."
  • No rash, no neck stiffness, no photophobia, no unusual cry, no bulging fontanelle.
  • Source: No cough, no runny nose. "His nappy has smelled funny the last two days — a bit strong." Crying when she changes him. Last proper wet nappy was about 6 hours ago.
  • Feeding: Refused breakfast, had some milk this morning but much less than normal.
  • Activity: "He's just lying there — normally he's into everything."
  • Immunisations: Up to date. No recent vaccines. No travel.
  • PMH: Born at term, no problems. No previous illnesses. No medications. No allergies.
  • Parental concern: "I know something is really wrong — this isn't like him at all."
🔔 Examiner Cues ▼
  • If candidate hasn't asked about urine by 3 minutes: Mother volunteers — "Actually, his nappy has been a bit smelly..."
  • If candidate hasn't asked about red flags: Prompt — "Is there anything specific about the rash you wanted to ask about?"
  • At the end, ask candidate: "What is your assessment and what do you do next?"

📄 Candidate Instructions

You are the ED doctor. Miss Chloe Reid, 19 years old, has been brought in by ambulance after her flatmate found her unconscious. She has now regained consciousness and GCS is 15. An empty blister pack of paracetamol 500mg (32 tablets) and an empty bottle of wine were found at the scene.

Obs: GCS 15, HR 96, BP 108/72, RR 16, SpO₂ 99%.

Please take a focused history. You have 8 minutes. Be mindful of the patient's emotional state.

💡 Key areas ▼
  • Toxicology: What substance(s) taken, exact amount, time of ingestion, any alcohol/other drugs, staggered dose vs single, any vomiting after.
  • Paracetamol specifics: Time since ingestion critical for Rumack-Matthew nomogram. Modified-release tablets? Liver disease (increased risk). Fasting/malnourished (depleted glutathione — increased risk).
  • Intent: Planned vs impulsive, note left, final acts, precipitant, ongoing wish to die — sensitively but directly.
  • Psychiatric history: Previous attempts, self-harm, depression, bipolar, psychosis, current psychiatric follow-up, medications, inpatient admissions.
  • Risk assessment: Current suicidal ideation, protective factors (family, future plans), access to means.
  • Social: Support network, recent stressors (relationship, exams, bereavement), alcohol/drug use, safeguarding (if applicable).
  • Allergies and current medications.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Chloe Reid. You are tearful and embarrassed. You took 16 paracetamol tablets (not 32 — she didn't count) approximately 4 hours ago after a relationship breakdown. You drank half a bottle of wine. This was impulsive — no note, no plan. You feel ashamed and say "I just didn't want to feel anything anymore." You are not actively suicidal now but feel hopeless.

🎭 Patient Script ▼
  • Ingestion: About 4 hours ago. "I don't know exactly how many — maybe 15 or 16." Standard 500mg tablets from the bathroom cabinet. Half bottle of red wine. No other drugs. Did not vomit.
  • Intent: "My boyfriend broke up with me this morning. I just snapped." No note. No previous plans. "I don't really want to die — I just couldn't cope."
  • Current ideation: "Not really... I feel stupid now." No active plan or intent currently.
  • PMH: Anxiety — on sertraline 50mg. No previous overdose attempts. One episode of self-harm (cutting) at age 16, not current. Sees GP but no psychiatrist.

A 24-year-old male footballer presents after twisting his right knee during a match 2 hours ago. He felt a "pop" and immediate pain. The knee has rapidly swollen. He cannot weight-bear.

Please perform a focused right knee examination. The examiner will provide findings as you examine. Present your diagnosis and management plan.

🔑 Structured Approach — Look, Feel, Move, Special Tests ▼
  • Look: Swelling (haemarthrosis vs effusion), bruising, deformity, muscle wasting (quadriceps), skin changes, scars.
  • Feel: Temperature, joint line tenderness (medial JL — MCL/medial meniscus; lateral JL — LCL/lateral meniscus), patella, tibial tuberosity, fibular head, popliteal fossa.
  • Move: Active then passive flexion/extension (normal 0–135°), patellar tracking.
  • Effusion tests: Patellar tap (large effusion), bulge sign / stroke test (small effusion).
  • Special tests:
    • ACL — Lachman test (most sensitive), anterior drawer test
    • PCL — posterior drawer test
    • MCL — valgus stress test at 0° and 30°
    • LCL — varus stress test at 0° and 30°
    • Meniscus — McMurray's test, Thessaly's test
  • Ottawa knee rules: XR indicated if: age ≥55, isolated patella tenderness, fibular head tenderness, unable to flex to 90°, unable to weight bear 4 steps immediately and in ED.

⚠️ Examiner Instructions — Not for Candidate

Findings represent an ACL tear with haemarthrosis. Feed findings as candidate examines each area.

📋 Findings to Feed ▼
  • Look: Marked diffuse swelling right knee. Mild bruising medially. No deformity. Quadriceps wasting not yet present (acute injury).
  • Feel: Warm. Tense haemarthrosis — patellar tap positive. Medial joint line tender. No isolated bony tenderness patella or fibular head.
  • Move: Active ROM limited by pain and swelling — flexion 0–80°. Extension full but painful.
  • Lachman test: Positive — anterior tibial displacement >5mm, soft endpoint. (Most sensitive ACL test)
  • Anterior drawer: Positive.
  • Valgus/varus stress: Stable — no MCL/LCL laxity.
  • McMurray's: Unable to complete fully due to pain, but medial joint line discomfort on internal rotation.
  • Neurovascular: Intact — DP and PT pulses present, sensation normal.
  • Diagnosis: ACL tear with acute haemarthrosis. Consider concurrent medial meniscus injury.

A 68-year-old man presents with a sudden onset acutely painful red right eye, blurred vision and he describes seeing halos around lights. He has been vomiting.

Please perform a focused eye examination, talk through your findings, and state your diagnosis and immediate management.

🔑 Structured Eye Exam Approach ▼
  • Visual acuity: Each eye separately — Snellen chart or counting fingers/hand movements/light perception. Pinhole VA.
  • Visual fields: Confrontation testing — all four quadrants each eye.
  • Pupils: Size, shape, reactivity to light (direct and consensual). RAPD (relative afferent pupillary defect) — swinging flashlight test.
  • Extra-ocular movements: H-pattern. Diplopia, pain on movement (optic neuritis, orbital cellulitis).
  • Anterior segment inspection: Periorbital — proptosis, lid swelling. Conjunctiva — injection pattern (ciliary flush = anterior uveitis/glaucoma; diffuse = conjunctivitis). Cornea — clarity, staining with fluorescein. Anterior chamber — depth (shallow = angle closure glaucoma), hyphaema, hypopyon.
  • Intraocular pressure: Tonometry — normal 10–21 mmHg. In acute angle closure — typically >40 mmHg. Palpation (crude — firm eye).
  • Fundoscopy: Disc margins, cupping (glaucoma — increased C:D ratio), macular changes, vessel changes.
  • Key diagnosis here: Acute angle closure glaucoma — mid-dilated fixed oval pupil, steamy/hazy cornea, shallow anterior chamber, markedly elevated IOP, ciliary flush, severe pain + vomiting + halos.

⚠️ Examiner Instructions — Not for Candidate

Findings represent acute angle closure glaucoma. This is an ophthalmic emergency. If candidate does not recognise it or does not urgently refer to ophthalmology, prompt with: "The patient says his vision is getting worse and the eye feels rock hard — what do you think is happening?"

📋 Findings to Feed ▼
  • VA: Right eye — hand movements only (severely reduced). Left eye — 6/6.
  • Pupils: Right pupil — mid-dilated (5mm), oval, fixed and non-reactive to light. Left pupil — normal, 3mm, reactive.
  • No RAPD on the left side.
  • Anterior segment: Right eye — circumcorneal (ciliary) flush. Cornea hazy/steamy. Anterior chamber appears shallow. No hyphaema.
  • IOP (palpation): Right eye markedly firm/hard on palpation compared to left.
  • EOM: Full and painless.
  • Diagnosis: Acute angle closure glaucoma right eye. Ophthalmic emergency.

📄 Candidate Instructions

A 32-year-old man presents with a right anterior shoulder dislocation following a fall onto an outstretched arm. XR confirms anterior dislocation with no fracture. Neurovascular status is intact pre-procedure.

Please describe and demonstrate on the manikin how you would reduce this shoulder dislocation. Include your choice of analgesia/sedation, technique, and post-reduction management.

📝 Reduction Techniques & Key Points ▼
  • Pre-reduction: Confirm XR (anterior dislocation — loss of normal contour, humeral head inferior and medial to glenoid). Neurovascular exam — axillary nerve (regimental badge area, deltoid power), radial nerve, brachial pulse.
  • Analgesia/sedation: IV opioid analgesia + Entonox. OR procedural sedation (midazolam + fentanyl / propofol / ketamine) with monitoring and resuscitation equipment ready. OR intra-articular lidocaine (10–20 ml 1% lidocaine into joint — effective, less sedation risk).
  • Techniques:
    • Cunningham technique (no sedation needed) — seated patient, gentle massage of biceps/deltoid/trapezius, patient relaxes, reduction occurs with gravity.
    • Stimson technique — prone, weight hanging from wrist, slow reduction with gravity.
    • External rotation technique (Leidelmeyer) — supine, elbow at 90°, slow external rotation to 90°.
    • Hippocratic / Kocher — historical, higher complication rates, not preferred.
  • Post-reduction: Confirm with XR. Repeat neurovascular exam. Sling immobilisation. Analgesia. Orthopaedic follow-up. Avoid abduction and external rotation 3–6 weeks.

⚠️ Examiner Instructions — Not for Candidate

Any evidence-based technique is acceptable. Assess pre/post neurovascular checks, analgesia adequacy, and whether candidate confirms success with XR. Ask: "The patient is very anxious and cannot relax — what do you do?" (Procedural sedation or intra-articular block).

CriterionMarks

📄 Candidate Instructions

A 45-year-old man with a GCS of 8 (E2V2M4) following a head injury is deteriorating. He has no gag reflex and his airway is at risk. SpO₂ is 91% on 15L O₂ via NRB. He is haemodynamically stable.

You have an experienced team available. Please talk through how you would perform a Rapid Sequence Induction (RSI) on this patient, including preparation, drug choices and post-intubation management.

📝 RSI Framework — 10 Ps ▼
  • Preparation: Team briefing, roles assigned (doctor — laryngoscopy; nurse — drugs; assistant — cricoid/MILS). SALAD setup. Plan B and C airway (SGA, surgical airway) ready.
  • Positioning: Ramped/sniffing position. MILS (manual in-line stabilisation) if C-spine not cleared.
  • Pre-oxygenation: 3–5 min high-flow O₂ via NRB or BVM. Aim EtO₂ >90%. THRIVE/HFNO during apnoea if available.
  • Pre-treatment (optional): Fentanyl 1–3 mcg/kg (attenuates ICP rise). Lignocaine (ICP — controversial). Atropine in children.
  • Paralysis with induction: Ketamine 1–2 mg/kg IV (head injury — previously controversial, now evidence neutral/beneficial for haemodynamically unstable; preferred if hypotensive). OR thiopentone 3–5 mg/kg (reduces ICP, avoid if hypotensive). + Suxamethonium 1.5 mg/kg IV (rapid onset, short duration — ideal RSI). OR Rocuronium 1.2 mg/kg (if suxamethonium CI — can reverse with sugammadex).
  • Protection: Cricoid pressure (Sellick's) — 10N awake, 30N after induction.
  • Placement: DL or VL. Visualise cords. ETT 7.5–8.5mm (men), 7–7.5mm (women). Cuff to 20–30 cmH₂O.
  • Proof: EtCO₂ waveform capnography — gold standard. Bilateral chest auscultation, SpO₂. CXR.
  • Post-intubation: Sedation and analgesia (propofol + fentanyl/morphine infusion). Ventilator settings. Maintain SpO₂ 94–98%, EtCO₂ 4.5–5.0 kPa (avoid hyperventilation in head injury unless coning). NG tube. Catheter. CT head. ITU referral.

⚠️ Examiner Instructions — Not for Candidate

Ask: "After your first intubation attempt you cannot see the cords — what do you do?" (CICO scenario). Expected: Call for help, optimise position/external laryngeal manipulation, second attempt with VL or bougie, SGA rescue, surgical airway as last resort — "can't intubate can't oxygenate" drill.

CriterionMarks
Preparation
Team briefing — roles assigned, plan B and C airway stated2
MILS applied — C-spine not cleared in head injury1

📄 Candidate Instructions

You are the ED registrar. Miss Abigail Turner, 34 years old, presented with pleuritic chest pain and breathlessness 3 days after a long-haul flight. A CTPA has confirmed a right-sided pulmonary embolism. She is haemodynamically stable and has been started on anticoagulation.

She is asking what the scan showed and what happens next. Please explain her diagnosis and management plan. She has no medical background.

💡 Key Points to Cover ▼
  • Explain diagnosis in plain English: A blood clot has formed in the veins (probably leg — ask if she had leg swelling) and travelled to the lung. Explain the scan confirmed this.
  • Why it happened: Long-haul flight — immobility, dehydration. Check for OCP use (risk factor). Check for previous clots or family history.
  • Treatment: Blood-thinning medication (anticoagulant) — DOAC (e.g. rivaroxaban or apixaban). Standard duration 3–6 months. Explain how to take, common side effects (bleeding risk), what to avoid (NSAIDs, contact sports), when to seek help.
  • Admission vs discharge: If low-risk (PESI score) and no home concerns — may be discharged same day or after short observation with community anticoagulation clinic follow-up.
  • Driving and flying: Can resume once stable on anticoagulation. Long-haul advised to wear compression stockings and stay mobile.
  • Thrombophilia screen: If first unprovoked PE — may need investigation for underlying clotting disorder.
  • Red flags to return: Increasing breathlessness, haemoptysis, syncope, leg swelling.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Abigail Turner. You are frightened. You are on the OCP (combined pill — risk factor candidate should pick up). Ask: "Will I have to stop my pill?" "Can I fly again?" "How long do I have to take the tablets?" "Could I have died?" If candidate communicates well, become visibly calmer. If rushed or uses jargon, remain anxious.

📄 Candidate Instructions

A 3-year-old boy, Thomas, has been brought to the ED by his mother with a bruised upper arm and a burn on his forearm. The mother says he "fell off the sofa" and "touched the oven." However, the nurse is concerned — the bruise is on the upper inner arm, the burn is circular, and Thomas has been withdrawn and non-communicative.

Please speak to the mother (Mrs Karen Dale) regarding the injuries and manage this situation appropriately. You have 8 minutes.

💡 Safeguarding Framework ▼
  • Injury features raising concern: Bruise — inner upper arm (unusual location for accidental injury, consistent with gripping), circular burn (consistent with cigarette burn — non-accidental), withdrawn affect in child.
  • During history: Take a clear, non-confrontational account of both injuries separately. Note inconsistencies. Record exact words used by carer. Ask about mechanism in detail. Ask about developmental stage (can a 3-year-old reach the oven?).
  • Do not accuse: Approach calmly and non-judgementally. Do not say "did you hurt him?" — use open questions.
  • Child-first assessment: Examine Thomas fully (with chaperone and consent) — head to toe, look for further injuries, growth centile.
  • Documentation: Accurate body map, dimensions, photographs with consent, exact history in quotes, time of injury vs presentation gap.
  • Immediate actions: Do not discharge. Discuss with senior colleague. Contact paediatric safeguarding lead. Refer to paediatrics. Notify social services / child protection team. Check child protection register (current concerns/previous attendances).
  • Inform parent appropriately: Tell the parent you are going to seek a second opinion — do not disclose full safeguarding concerns prematurely if child may be taken home and placed at further risk.

⚠️ Examiner / Role-player Instructions — Not for Candidate

You are Mrs Karen Dale. You give a vague, inconsistent account. For the bruise: "He just fell, kids bruise easily." For the burn: "He ran to the oven and touched it — I was right there." If asked if there is anyone else at home: "My partner, but he had nothing to do with this." Become defensive if candidate is accusatory. Remain co-operative if candidate is calm and professional. Do not volunteer that the partner has a history of domestic violence unless directly and sensitively asked about home safety.

CriterionMarks
History Taking
Takes separate detailed account of each injury — mechanism, timing, witness2
Notes developmental appropriateness — queries whether 3-year-old could reach oven1
Identifies inconsistencies — records in exact words, non-confrontational2
Asks about household members and home environment sensitively1
Approach
Non-accusatory — does not directly accuse or confront carer2
Remains professional and calm when carer becomes defensive2
Child-centred approach — prioritises Thomas's safety throughout1
Clinical & Safeguarding Actions
States full examination of Thomas — head to toe, body map, photograph2
Does not discharge — states child must not leave until assessed2
Refers to paediatrics and safeguarding lead1
Checks child protection register / previous attendances1

📄 Candidate Instructions

A 7-year-old girl is brought to the ED by her parents. She has been complaining of her "heart beating fast" for the last 45 minutes. She looks pale and is sweaty. She has had one previous episode that resolved spontaneously.

Obs: HR 240 bpm, BP 88/50, RR 28, SpO₂ 97%, GCS 15.

The examiner will describe the ECG. Interpret it systematically, state your diagnosis and outline your stepwise management.

💡 Paediatric SVT Management ▼
  • SVT ECG features: Rate 220–300 in children. Narrow complex (QRS <0.08s in children). No visible P waves (or retrograde P after QRS). Regular rhythm. Abrupt onset/offset.
  • Haemodynamically stable:
    1. Vagal manoeuvres — ice to face (diving reflex, most effective in infants/children), Valsalva (older children), carotid sinus massage (adults).
    2. Adenosine IV — 100 mcg/kg rapid IV bolus (max 6mg first dose) followed immediately by 10 ml saline flush. Can repeat 200 mcg/kg (max 12 mg) then 300 mcg/kg (max 18mg). Must be given centrally or large peripheral vein rapidly.
  • Haemodynamically unstable (this patient — BP 88/50, pale, sweaty): Proceed to synchronised DC cardioversion — 1 J/kg, then 2 J/kg. Sedate if conscious (ketamine, midazolam).
  • Post-conversion: 12-lead ECG — look for WPW (delta wave, short PR). Paediatric cardiology referral. Consider prophylactic flecainide/propranolol if recurrent.

⚠️ Examiner Instructions — Not for Candidate

Read the ECG description. Key assessment: does the candidate recognise haemodynamic compromise and go straight to cardioversion rather than adenosine? Ask: "A junior doctor suggests trying adenosine first — what do you think?"

📋 ECG Description to Read ▼

"Rate approximately 240 bpm, completely regular. Narrow complex QRS — duration approximately 0.06 seconds. No discernible P waves. No ST changes. Axis normal."

Follow-up Q1: "You cardiovert at 1 J/kg — sinus rhythm is restored. The post-conversion ECG shows a short PR interval and a slurred upstroke on the QRS. What does this suggest?"

Expected: Wolff-Parkinson-White syndrome (WPW) — delta wave, short PR, wide QRS. Requires paediatric cardiology referral. Avoid AV nodal blocking agents (adenosine, digoxin, verapamil) in WPW with AF as may accelerate conduction via accessory pathway → VF.

Follow-up Q2: "Can this child go home today?"

Expected: No — needs paediatric cardiology review, possible electrophysiology study and catheter ablation. Admit under paediatrics. Parents educated on vagal manoeuvres and when to return.

CriterionMarks

Sedation/analgesia before cardioversion if time permits and child conscious1
Post-conversion 12-lead ECG — identifies WPW features (delta wave, short PR)2
WPW — avoids adenosine/digoxin/verapamil, explains risk2
Paediatric cardiology referral — does not discharge1
Communicates clearly with team and family throughout1

📄 Candidate Instructions

A 72-year-old man on warfarin (AF) has been brought in following a fall downstairs. GCS was 14 at scene, now 11/15 (E3V3M5) and deteriorating. He has a boggy scalp haematoma over the right temporal region.

The CT head has been reported by the radiographer as "abnormal." The examiner will describe the CT findings to you. Please interpret them, state your diagnosis, and outline immediate management.

💡 CT Head Interpretation Framework ▼
  • Blood is bright (hyperdense) on CT — "Blood Is Bright."
  • Location of bleeds:
    • Extradural (EDH): Biconvex (lens-shaped), does not cross sutures. Often temporal (MMA rupture). Lucid interval. Arterial bleed.
    • Subdural (SDH): Concave (crescent-shaped), crosses sutures, follows brain surface. Bridging vein rupture. Common in elderly/anticoagulated.
    • Subarachnoid (SAH): Hyperdensity in sulci/basal cisterns (star pattern). Thunderclap headache.
    • Intracerebral (ICH): Hyperdense within brain parenchyma. Hypertension most common cause.
  • Midline shift: Normal midline = falx cerebri. Shift >5mm = significant mass effect. Direction = away from bleed.
  • Herniations: Uncal — transtentorial (CN III palsy — ipsilateral fixed dilated pupil). Tonsillar — through foramen magnum → coning (Cushing's triad: hypertension, bradycardia, irregular respirations).
  • Other features: Skull fractures (linear, depressed), pneumocephalus, effacement of sulci (cerebral oedema).

⚠️ Examiner Instructions — Not for Candidate

Read the CT description aloud. The critical management point is immediate anticoagulation reversal and urgent neurosurgical referral. Ask: "The neurosurgeon asks about his INR — it's 4.2. What do you do?"

📋 CT Description to Read ▼

"There is a hyperdense crescent-shaped collection overlying the right cerebral hemisphere, maximum thickness 18mm, consistent with an acute subdural haematoma. There is approximately 8mm of midline shift to the left. Sulci are effaced on the right. No skull fracture visible on bone windows. Basal cisterns are present but reduced on the right. Left hemisphere appears normal."

Follow-up Q1: "INR is 4.2. What do you do?"

Expected: Immediate reversal — Vitamin K 5–10mg IV + 4-factor PCC (Prothrombin Complex Concentrate, e.g. Beriplex) dosed by weight and INR. Target INR <1.5 before surgery. Do NOT wait for FFP alone. Contact haematology for guidance.

Follow-up Q2: "While waiting for neurosurgery the patient's right pupil becomes fixed and dilated. What is happening and what do you do?"

Expected: Uncal herniation — CN III compression by expanding haematoma. This is pre-terminal. Immediately: call neurosurgery for emergency burr hole. Temporising: head of bed 30°, osmotherapy (mannitol 0.5–1g/kg IV or hypertonic saline 3%), avoid hypoxia/hypotension/hypercapnia. Consider intubation if GCS deteriorating.

CriterionMarks
CT Interpretation
States systematic approach — confirms patient details, date, side marker1
Correctly identifies hyperdense crescent-shaped collection — subdural haematoma2
Correctly lateralises — right-sided1
Identifies midline shift — direction and approximate magnitude (8mm to left)2
Notes sulcal effacement — cerebral oedema / mass effect1
Correctly distinguishes SDH from EDH — crescent shape, crosses sutures1
Immediate Management
Urgent neurosurgical referral — does not delay2
Anticoagulation reversal — Vitamin K + PCC (Beriplex). Not FFP alone. Target INR <1.53
Herniation Response
Correctly identifies uncal herniation — CN III palsy, ipsilateral fixed dilated pupil2
Appropriate temporising measures — osmotherapy, head up, avoid secondary insults2
States emergency surgical decompression required — burr hole1
Airway management — considers RSI for GCS deterioration1
