What are the priority interventions for the nurse managing patient symptoms of an acute myocardial infarction (AMI) in the ED? (Select all that apply)

Rationale: A. Administration of naloxone is incorrect because naloxone is an opioid antagonist used for opioid overdose, not for AMI. It has no role in managing myocardial ischemia. B. Administration of aspirin is correct because aspirin inhibits platelet aggregation, reducing further clot formation in a coronary artery. Early administration of aspirin in suspected AMI improves outcomes and reduces mortality. C. Oxygen therapy is correct because oxygen is given to increase oxygen delivery to ischemic myocardium, particularly in patients who are hypoxic, have dyspnea, or show signs of heart failure. Routine oxygen is reserved for patients with SpO₂ < 94%, per current guidelines. D. Administration of morphine is correct because morphine relieves severe chest pain and reduces sympathetic stimulation, which can decrease myocardial oxygen demand. Morphine also helps alleviate anxiety associated with AMI. E. Dopamine infusion is incorrect as a first-line intervention for AMI unless the patient has hemodynamic instability such as hypotension with poor perfusion. Dopamine is a vasopressor and inotrope, not routinely indicated for stable AMI management. F. Administration of nitroglycerin is correct because nitroglycerin dilates coronary arteries, improving myocardial perfusion and reducing ischemic chest pain. It also reduces preload and myocardial oxygen demand. Care is needed in patients with hypotension or right ventricular infarction.
