The nurse is reviewing the client's medical record. A nurse is reviewing the client's diagnostic results and vital signs. Which of the following actions should the nurse take? Select all that apply.

This client presents with clinical, laboratory, and electrocardiographic findings consistent with an acute ST-segment elevation myocardial infarction (STEMI). The priority of care is rapid restoration of coronary blood flow, prevention of further thrombus formation, and reduction of myocardial oxygen demand. Management involves urgent invasive intervention, anticoagulation therapy, and stabilization of cardiac workload. Nursing actions must align with emergency cardiac protocols to prevent irreversible myocardial damage and complications. A. Anticipating preparation for cardiac catheterization is appropriate because ST-segment elevation on ECG indicates an acute coronary artery occlusion requiring urgent reperfusion therapy. Cardiac catheterization allows for coronary angiography and possible percutaneous coronary intervention (PCI) to restore blood flow and limit myocardial damage. This is a priority intervention in STEMI management. B. Assisting with a continuous heparin infusion is appropriate because anticoagulation helps prevent further clot formation and limits extension of the coronary thrombus. Heparin is commonly used in acute myocardial infarction to reduce the risk of additional ischemic injury. It supports stabilization until definitive revascularization is achieved. C. Encouraging the client to ambulate is contraindicated in the acute phase of myocardial infarction. Physical activity increases myocardial oxygen demand and can worsen ischemia or precipitate dysrhythmias. The client should be placed on bed rest to reduce cardiac workload and prevent complications. D. Anticipating an increased dosage of metoprolol is appropriate because beta-blockers reduce heart rate, blood pressure, and myocardial oxygen consumption. This helps limit infarct size and prevent dysrhythmias in acute coronary syndrome. Careful titration is necessary based on hemodynamic stability. E. Obtaining a prescription for NPO status is appropriate because the client is likely to undergo urgent cardiac catheterization or possible surgical intervention. Maintaining NPO status reduces the risk of aspiration during procedures requiring sedation or anesthesia. This is standard pre-procedural preparation. F. Requesting a prescription for an antibiotic is not appropriate because there is no evidence of infection. The findings indicate acute myocardial infarction rather than an infectious process. Antibiotics are not part of the management of STEMI unless a separate infection is identified.
