Question 5 of 5
A client is hospitalized after experiencing a myocardial infarction (MI). To reduce cardiac workload, which intervention should the nurse include in the client's plan of care?
Correct Answer: C
Rationale: Providing a bedside commode reduces cardiac workload in a client post-myocardial infarction (MI) by minimizing physical exertion. After an MI, the heart's oxygen demand must be kept low to prevent further damage, and activities like walking to the bathroom increase energy expenditure and strain. Using a commode allows the client to toilet without ambulating, conserving energy. Active exercises or hallway ambulation increase oxygen demand, while side-lying positioning, though helpful for comfort, doesn't directly address exertion as effectively as the commode.
