Emergency and Acute Care
Recognition and Prioritization
Emergency care questions reward a systematic approach: airway, breathing, circulation, disability, exposure, followed by focused history and intervention. Candidates must recognize time-critical patterns such as shock, anaphylaxis, tension pneumothorax, cardiac tamponade, sepsis, stroke, and acute coronary syndrome. Understand triage principles, the difference between stabilization and definitive care, and when to activate a team or transfer. Know basic resuscitation concepts, oxygen delivery, vascular access, and the role of rapid reassessment.
Stabilize First
A central rule is that life-threatening problems are treated before diagnosis is confirmed. In unstable patients, bedside interventions and empiric treatment precede imaging. Understand that hypotension with distended neck veins and muffled heart sounds suggests tamponade, and that unilateral absent breath sounds with tracheal deviation suggests tension pneumothorax, both requiring immediate decompression rather than imaging.
Traps
Common traps: ordering a CT scan in an unstable patient, giving a medication before addressing airway, and missing atypical presentations in older adults, pregnant patients, and immunocompromised patients. Another trap is treating a number rather than a patient, such as aggressively lowering blood pressure in an acute stroke without indication.
Worked Example
Rule of thumb: if the patient is unstable, the next step is an intervention you can do at the bedside, not a test that requires transport. For a hypotensive trauma patient with a positive bedside ultrasound showing free fluid, proceed to operative or definitive hemorrhage control rather than sending the patient to the scanner.
