SMLE Emergency Medicine MCQs: Practice Questions With Explanations
Sample SMLE MCQs from Emergency Medicine — an 82-question core clinical domain in HighYield's SMLE bank without a dedicated practice post yet — covering the primary survey, anaphylaxis, and life-threatening chest and cardiac emergencies.
Emergency Medicine is an 82-question core clinical domain in HighYield's SMLE question bank without a dedicated practice post yet. Below is a sample set of Emergency Medicine MCQs in clinical-vignette style, grouped by theme.
The Primary Survey
1. In the ABCDE primary survey approach to an unstable patient, the step addressed immediately after Airway (with cervical spine control) is:
- A) Disability assessment
- B) Breathing and ventilation ✅
- C) Exposure and environmental control
- D) Circulation with hemorrhage control
2. A trauma patient with tracheal deviation, absent breath sounds on one side, and hemodynamic instability should be managed immediately with:
- A) Chest X-ray to confirm the diagnosis first
- B) Needle decompression ✅
- C) Intravenous antibiotics
- D) Diuretics
Anaphylaxis
3. The first-line treatment for anaphylaxis is:
- A) IV corticosteroids

- B) Anterolateral thigh (vastus lateralis) ✅
- C) Gluteal region
- D) Forearm
Life-Threatening Chest and Cardiac Emergencies
5. Beck's triad — hypotension, jugular venous distension, and muffled heart sounds — is classically associated with:
- A) Tension pneumothorax
- B) Cardiac tamponade ✅
- C) Massive pulmonary embolism
- D) Aortic dissection
6. ST-segment elevation in leads V1 through V4 on ECG most classically localizes a myocardial infarction to the:
- A) Inferior wall
- B) Anterior wall ✅
- C) Lateral wall
- D) Posterior wall
Why Emergency Medicine Deserves Dedicated Revision
Emergency Medicine vignettes on the SMLE reward fast pattern recognition under a time-pressured format — the primary survey sequence, the first drug and dose reflex for anaphylaxis, and the handful of classic triads and ECG patterns that flag an immediately life-threatening diagnosis. These are exactly the kind of associations that MCQ repetition locks in far better than passive reading.
