Sample itemWhat is the usual first investigation for a patient with suspected acute coronary syndrome?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. 12-lead electrocardiogram
A 12-lead ECG should be obtained promptly in suspected acute coronary syndrome because it may show acute ischaemia or infarction requiring time-sensitive treatment.
Option by option
A. 12-lead electrocardiogram (correct)
Correct: ECG can rapidly identify ischaemic changes.
B. Plain abdominal radiograph
Abdominal radiography does not evaluate coronary ischaemia.
C. Skin prick testing
Skin testing assesses allergic sensitisation.
D. Peak expiratory flow
Peak flow assesses obstructive airway disease.
