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 referral for cardiac rehabilitation?

Rationale: A. "I'm too tired to brush my teeth.": Extreme fatigue with minimal activity is a sign of functional limitation and deconditioning associated with heart failure. Cardiac rehabilitation is designed to improve exercise tolerance, enhance physical function, and provide structured activity programs tailored to the client’s cardiovascular capacity. Referral is indicated when daily activities are significantly impacted by fatigue or dyspnea. B. "I will weigh myself daily.": Daily weight monitoring is an appropriate self-management strategy for heart failure, allowing early detection of fluid retention. This indicates client engagement and does not suggest a need for additional rehabilitation services, as it reflects adherence rather than functional limitation. C. "I hate how I feel all the time.": While expressing frustration or low mood may indicate emotional distress or depression, it does not directly indicate a functional limitation that necessitates cardiac rehabilitation. Emotional support or counseling may be appropriate, but it is not the primary trigger for rehab referral. D. "I need to start eating a low-sodium diet.": Initiating a low-sodium diet is a standard component of heart failure self-care to manage fluid balance and prevent exacerbations. This reflects the need for education rather than the need for cardiac rehabilitation focused on improving functional activity.
