A nurse is planning discharge teaching for a client who has heart failure. Which of the following instructions should the nurse include in the teaching?

Discharge teaching for a client with Heart failure focuses on preventing fluid overload, reducing cardiac workload, and recognizing early signs of decompensation. Heart failure is characterized by the heart’s inability to pump effectively, leading to fluid retention, pulmonary congestion, and systemic edema. Daily monitoring of weight is one of the most sensitive indicators of fluid status changes. Patient education is essential to help clients identify worsening symptoms early and seek timely intervention. Rationale: A. Exercising twice per week is insufficient guidance because heart failure patients are generally encouraged to engage in regular, moderate, and individualized activity as tolerated, rather than infrequent exercise. Activity should be balanced with rest periods and guided by symptoms such as dyspnea and fatigue. Regular low-to-moderate intensity exercise improves cardiac efficiency and functional capacity over time. B. Reporting a weight gain of 0.9 kg (2 lb) in 1 day is correct because sudden weight gain is an early sign of fluid retention and worsening heart failure. This indicates the body is retaining excess fluid before overt symptoms such as edema or shortness of breath develop. Prompt reporting allows early adjustment of diuretic therapy and prevents hospitalization due to acute decompensation. C. Restricting sodium intake to 5 g per day is incorrect because this level is too high for a client with heart failure. Sodium restriction is typically much lower (often around 2 g per day or less) to prevent fluid retention. Excess sodium intake promotes water retention, worsening edema and increasing cardiac workload. D. Increasing fluid intake to 3 L per day is inappropriate because excess fluid intake can worsen volume overload in heart failure. Most clients are placed on fluid restrictions tailored to their condition, often between 1.5–2 L per day depending on severity. Excess fluid increases preload and can lead to pulmonary congestion and peripheral edema.
