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?

Limiting dietary sodium reduces fluid retention, which decreases preload and the workload on the failing heart. Exercise restriction is not recommended — moderate, supervised exercise improves cardiac function and quality of life. Large meals increase oxygen demand during digestion; small, frequent meals are recommended. Daily weight monitoring (not weekly) is essential to detect early fluid retention — a gain of more than 1 kg (2.2 lb) in a day or 2–3 kg in a week should be reported to the provider.
