Which of the following is not typically recommended in the immediate management of suspected MI?

• A. Administer aspirin
• B. Administer oxygen
• C. Administer thrombolytics
• D. Administer a broad-spectrum antibiotic

Answer: (D)

Immediate MI management focuses on rapidly relieving ischemia and restoring blood flow. Aspirin helps by inhibiting platelets and reducing further clot progression, which is essential to limit heart muscle damage. Oxygen is given when the patient is hypoxemic to ensure adequate oxygen delivery to the heart, supporting myocardial recovery. Thrombolytics are used to dissolve the obstructing clot and re‑establish blood flow when reperfusion therapy isn’t immediately available, making them a key part of acute treatment in appropriate cases. A broad-spectrum antibiotic does not address the underlying problem of ischemia or the thrombotic occlusion; it treats infections, not myocardial injury, so it isn’t part of the immediate MI management unless there is a separate infection that requires antimicrobial therapy.
