The nurse is caring for a client recovering from a recent myocardial infarction. To reduce cardiac workload, which intervention should the nurse include in the client's plan of care?

A. Assist with ambulation in the hallway: While progressive ambulation is part of cardiac rehabilitation, early ambulation too soon after a myocardial infarction may increase myocardial oxygen demand and cardiac workload. B. Provide a bedside commode for toileting: Using a bedside commode reduces the effort and energy expenditure required to walk to the bathroom, thus lowering cardiac workload. This helps prevent unnecessary increases in heart rate and oxygen demand. C. Encourage active range of motion exercise: Active range of motion is beneficial for preventing complications like thromboembolism, but if done too aggressively or frequently early post-MI, it can stress the heart. D. Teach to sleep in a side-lying position: Sleeping position may affect comfort and breathing but does not significantly influence cardiac workload. Semi-Fowler’s position may be more beneficial in reducing preload in cardiac patients than simply lying on the side.
