A nurse is planning care for a client who is recovering from an acute myocardial infarction that occurred 3 days ago. Which of the following interventions should the nurse include?

Rationale: A. Perform an ECG every 12 hr: Frequent ECGs are typically done during the acute phase to monitor for arrhythmias, but by day 3 post-MI, continuous or as-needed monitoring is more appropriate unless new symptoms occur. B. Obtain a cardiac rehabilitation consultation: Early involvement of cardiac rehab supports gradual activity progression, lifestyle modification, and psychosocial support, improving long-term outcomes after MI. C. Draw a troponin level every 4 hr: Troponin testing is most useful for diagnosing and trending damage during the first 24 hours; by day 3, levels have usually peaked and are declining. D. Place the client in a supine position while resting: Supine positioning can increase cardiac workload; a semi-Fowler's position is preferred to reduce venous return and ease breathing.
