A client in the intensive care unit is experiencing an ST-elevation myocardial infarction (STEMI) confirmed by the 12-lead EKG. Which of the following interventions will the nurse anticipate for this client?

Choice A reason: Discontinuing intravenous access is inappropriate for a STEMI client, as IV access is critical for administering medications like anticoagulants, antiplatelets, and thrombolytics, or for emergency interventions. Maintaining IV access supports rapid treatment to restore coronary blood flow, which is essential in managing acute myocardial infarction effectively. Choice B reason: A non-contrast CT scan is not typically indicated for STEMI management. STEMI is diagnosed via EKG and requires urgent revascularization, often through cardiac catheterization. CT scans may be used for other conditions, like stroke, but they do not address the urgent need to restore coronary artery perfusion in STEMI. Choice C reason: Holding anticoagulant therapies is contraindicated in STEMI, as these medications (e.g., heparin) prevent further clot formation and stabilize the existing thrombus. Anticoagulants are critical in conjunction with revascularization procedures like cardiac catheterization to improve blood flow and reduce myocardial damage in acute infarction. Choice D reason: Cardiac catheterization is the standard intervention for STEMI, allowing visualization and treatment of coronary artery blockages via percutaneous coronary intervention (PCI). It restores blood flow to the ischemic myocardium, minimizing tissue damage. The nurse anticipates this procedure as it directly addresses the underlying cause of STEMI, a blocked coronary artery.
