A nurse is assessing a client who has heart failure. Which of the following client statements should indicate to the nurse that the client needs a referral for cardiac rehabilitation?

Rationale: A. "I will weigh myself daily." Weighing oneself daily is a recommended practice for clients with heart failure to monitor fluid retention. It does not suggest a need for cardiac rehabilitation as it helps with self-management. B. "I'm too tired to brush my teeth." This statement suggests severe fatigue and reduced physical functioning, indicating the need for cardiac rehabilitation. It can help improve endurance, strength, and overall quality of life. C. "I hate how I feel all the time." This statement indicates dissatisfaction with the condition, but it does not suggest a specific need for cardiac rehabilitation. It may signal emotional distress or depression, but not necessarily a physical activity issue. D. "I need to start eating a low-sodium diet." Eating a low-sodium diet is part of heart failure management, it does not indicate the need for cardiac rehabilitation. Diet changes are essential but don't directly relate to physical rehabilitation.
