A home health nurse is visiting a client who is recovering from coronary artery bypass surgery and reports experiencing stress. The nurse should determine that which of the following factors might interfere with the client's recovery?

A. Walking the dog daily is a form of mild physical activity, which is typically beneficial for recovery from surgery and does not interfere with healing. In fact, regular moderate exercise promotes circulation and cardiovascular health. B. Stopping caffeine can be beneficial for some patients, particularly those with heart conditions, as it can reduce stress and decrease the risk of arrhythmias. This would not interfere with the client's recovery. C. Morning exercise can be part of a healthy recovery routine if it is within the client's capacity and the exercise is moderate. It helps maintain circulation and physical strength, promoting recovery after surgery. D. The emotional stress from the loss of a close friend can interfere with recovery, particularly after major surgery. Emotional well-being plays a significant role in physical recovery, and the client may need additional support to manage this stress.
