Correct answer: A — Upright sitting position (45° or more)

A patient experiencing a suspected cardiac event (MI, angina, cardiac arrhythmia) should be positioned upright or semi-reclined (45° or more) to reduce venous return, decrease cardiac workload, and facilitate breathing. The supine position with legs elevated (Trendelenburg) is appropriate for syncope and shock but is contraindicated in cardiac events as it increases preload and cardiac workload. The exception is if the patient becomes hypotensive/unconscious — then position supine for CPR readiness.
