A client has presented to the emergency department with an acute myocardial infraction (MI). What action by the nurse is best for optional client outcomes?

A. Give the client a nonenteric coated aspirin.: Early administration of non–enteric-coated aspirin is a cornerstone of acute myocardial infarction management. Aspirin irreversibly inhibits platelet aggregation by blocking cyclooxygenase-1 (COX-1), reducing thrombus formation in the coronary arteries. Chewable, non–enteric-coated aspirin ensures rapid absorption. B. Notify the Rapid Response Team immediately.: The Rapid Response Team is activated for acute clinical deterioration in hospitalized patients, not for initial management of a stable client presenting to the emergency department with suspected MI. This does not directly contribute to timely reperfusion or improved myocardial outcomes. C. Obtain an electrocardiogram (ECG) within 20 minutes.: Guidelines recommend obtaining a 12-lead ECG within 10 minutes of arrival for suspected MI. While obtaining an ECG is critical for diagnosis, the timeframe listed is not optimal and delays recognition and treatment. Early ECG is essential, but this is not the best immediate intervention for improving outcomes. D. Prepare to administer thrombolytics within 60 minutes.: Thrombolytic therapy is important in ST-elevation myocardial infarction (STEMI) when percutaneous coronary intervention is unavailable, with a goal door-to-needle time of 30 minutes. A 60-minute timeframe exceeds recommended guidelines and delays reperfusion.
