MONA stands for which initial treatment components in MI management?

• A. Morphine, Oxygen, Nitrates, Aspirin
• B. Morphine, Oxygen, Nitroglycerin, Acetaminophen
• C. Meperidine, Oxygen, Nitrites, Anticoagulant
• D. Morphine, Oxygen, Niacin, Antiplatelet

Answer: (A)

In acute myocardial infarction, the goal is rapid relief of ischemia, reduction of heart workload, and prevention of further clot formation. The MONA sequence captures the classic initial pharmacologic actions to achieve that. Morphine provides pain relief and helps reduce sympathetic drive, which lowers myocardial oxygen demand. Oxygen is given if the patient is hypoxic or in evident respiratory distress to ensure the heart and tissues receive adequate oxygen. Nitrates, such as nitroglycerin, dilate veins and coronaries, decreasing preload and afterload and improving blood flow to the heart while also easing chest pain. Aspirin is given immediately to inhibit platelet aggregation, helping prevent further thrombus growth and reducing mortality when started early. The other options include drugs that don’t address these immediate goals as directly, such as acetaminophen or niacin, or mix in agents not part of this mnemonic. Historically, MONA guided initial MI care, though contemporary practice uses oxygen more selectively based on oxygenation status.
