A client with coronary artery disease is hospitalized with unstable angina. To reduce cardiac workload, which intervention should the nurse include in the client's plan of care?

A. Range of motion exercises are important for overall mobility and prevention of complications from immobility. However, they can increase cardiac workload, especially if performed actively and without supervision. B. Ambulation, or walking in the hallway, increases cardiac workload and can exacerbate symptoms in a client with unstable angina. This activity should be minimized or restricted until the client's condition stabilizes. The focus should be on reducing activities that put additional stress on the heart. C. Using a bedside commode helps reduce the need for the client to walk to the bathroom, which can be physically demanding and increase cardiac workload. By minimizing the effort required for toileting, the client can avoid unnecessary physical strain. D. Sleeping in a side-lying position is not directly related to reducing cardiac workload. The client's position during sleep generally does not have as significant an impact on cardiac workload as other interventions.
