Acute and emergency medicine is one of the highest-yield areas in PLAB 1 because it's decision-heavy and safety-critical: the exam repeatedly tests the acutely unwell patient — sepsis, anaphylaxis, shock — and the single most important immediate action. The recurring skill is recognising the emergency and choosing the right first step, usually within an ABCDE framework. Knowing what to do first matters more here than exhaustive detail, which makes this a high-return area to revise.
Key takeaways
- Emergencies are safety-critical and decision-heavy — perfect for the "most appropriate next step" format.
- Must-know: sepsis, anaphylaxis, shock, acute coronary syndrome, acute asthma/COPD, DKA, PE, GI bleed.
- The governing principle is ABCDE: stabilise first, before definitive investigation or treatment.
- The classic trap is the right action at the wrong time — a definitive test or treatment chosen too early.
- These apply equally to the UKMLA AKT, which shares the format and content map.
Why acute and emergency medicine is so high-yield
Emergencies are where decisions matter most and mistakes cause harm, so they're heavily examined and naturally suit single-best-answer "next step" questions. PLAB 1 is pitched at Foundation Year 2 level — the doctor who first assesses the acutely unwell patient — so recognising deterioration and taking the correct immediate action is core to what's being tested.
The must-know emergencies
| Emergency | Why it's tested | Key immediate decision | Common trap |
|---|---|---|---|
| Sepsis | Common, time-critical | Recognise early and start the sepsis six | Missing it; delaying treatment for investigations |
| Anaphylaxis | High-stakes, classic | Immediate IM adrenaline and ABCDE | Choosing antihistamine/steroid first, or delaying adrenaline |
| Shock (any cause) | Decision-heavy | Identify the type and resuscitate appropriately | Treating before identifying the cause |
| Acute coronary syndrome | Common, time-critical | ECG and immediate management | Delaying the time-critical step |
| Acute asthma / COPD | Common acute presentations | Grade severity and treat; oxygen targets | Under-treating severe asthma; wrong oxygen target in COPD |
| Diabetic ketoacidosis | Frequent emergency | Fluids, insulin and electrolyte management in the right order | Wrong sequence; missing potassium |
| Pulmonary embolism | High-yield | Risk-assess and investigate appropriately | Over- or under-investigating |
| Upper GI bleed | Common | Resuscitate first, then risk-score and scope | Endoscopy before resuscitation |
The ABCDE-first principle
The single most useful habit for emergency questions is the ABCDE approach: assess and stabilise Airway, Breathing, Circulation, Disability and Exposure before definitive investigation or treatment. When a stem offers a definitive scan or specialist treatment alongside a stabilising step, the stabilising step is usually the answer — the definitive option is the classic distractor, correct eventually but not first.
How to drill emergencies for the exam
Emergency questions reward a systematic approach plus review of timing errors. Practise mixed emergency scenarios, apply ABCDE every time, and for each wrong answer ask whether you misread the urgency or chose the right action at the wrong moment.
iatroX supports this: the Socratic Tutor works through the reasoning of an emergency stem — why stabilise before scanning, why adrenaline first in anaphylaxis — rather than just giving the answer, and Ask iatroX lets you confirm the immediate management against UK guidance (NICE, CKS, SIGN and the SmPC). The adaptive engine resurfaces the emergencies you're weakest on, and you can drill acute presentations through the UKMLA Academy. iatroX covers PLAB 1 and UKMLA on one subscription (£29/month or £99/year), with free sample questions.
Frequently asked questions
What emergency topics are most important for PLAB 1? Sepsis, anaphylaxis, shock, acute coronary syndrome, acute asthma and COPD, diabetic ketoacidosis, pulmonary embolism and upper GI bleed — all common, time-critical, and well suited to "next step" questions.
What is the ABCDE approach and why does it matter for the exam? ABCDE — Airway, Breathing, Circulation, Disability, Exposure — is the systematic way to assess and stabilise an acutely unwell patient. In the exam, the stabilising step usually comes before any definitive investigation or treatment.
Why do I keep getting emergency questions wrong despite knowing the condition? Usually a timing error — choosing a definitive investigation or treatment that's correct eventually but not the immediate next step. Applying ABCDE and asking "what must I do first?" fixes this.
Are these emergencies the same for the UKMLA AKT? Yes. The AKT shares the MLA content map and the single-best-answer format, so the high-yield emergencies and the ABCDE-first logic apply equally to UK finalists and IMGs.
