A nurse is providing teaching to a client who has heart failure and a decreased cardiac output. Which of the following information should the nurse include in the teaching?

Rationale: A. Restrict daily exercise: Clients with heart failure benefit from regular, moderate activity as tolerated to improve cardiac efficiency and prevent deconditioning. Restricting all exercise can worsen functional status and is not recommended unless specifically limited by the healthcare provider. B. Encourage 3 large meals per day: Large meals can increase cardiac workload and exacerbate heart failure symptoms due to increased blood flow demands during digestion. Smaller, more frequent meals are preferable to reduce strain on the heart. C. Limit dietary salt intake: Reducing sodium intake helps prevent fluid retention and edema, which can exacerbate heart failure and increase cardiac workload. Teaching clients to limit salt is a key intervention to manage decreased cardiac output and maintain stable fluid balance. D. Obtain weight once per week: Daily weight monitoring is recommended for clients with heart failure to detect fluid retention early. Weekly weights may delay recognition of sudden fluid accumulation, increasing the risk of decompensation.
