Which item is NOT part of general MI treatment?

• A. Antibiotics
• B. Morphine/pain control
• C. Oxygen
• D. Nitro

Answer: (A)

In myocardial infarction management, the goal is to rapidly relieve ischemia and support heart function. Oxygen is given when the patient is hypoxic to improve oxygen delivery to the heart. Nitro (nitroglycerin) helps by dilating vessels, which lowers preload and afterload, reduces myocardial oxygen demand, and often relieves chest pain. Morphine/pain control is used to ease severe discomfort and reduce sympathetic stimulation, which can otherwise worsen ischemia. Antibiotics, however, are not part of general MI treatment because there’s no infection driving the heart attack itself; antibiotics would be unnecessary unless there’s an unrelated infection present. So the item not part of standard MI care is antibiotics.
