A nurse is providing discharge teaching to a client who has a new diagnosis of heart failure. Which of the following instructions should the nurse include in the teaching?

Choice A rationale Regular, moderate-intensity aerobic exercise, such as walking or swimming, is recommended for clients with stable heart failure to improve functional capacity, quality of life, and endothelial function. The goal is typically at least 30 minutes of moderate activity 3 to 5 times per week, or as tolerated, but clients should avoid overexertion and heavy isometric exercise. Choice B rationale Diuretics increase the excretion of sodium and water, leading to increased urine output. Taking diuretics just before bed would necessitate frequent nighttime trips to the bathroom, disrupting sleep and increasing the risk of falls, especially in older adults. Diuretics are usually taken in the morning or early afternoon to manage nocturia. Choice C rationale Daily weight checks are the gold standard for monitoring fluid status in clients with heart failure. A weight gain of 2 pounds (0.9 kg) in one day or 5 pounds (2.3 kg) in one week should be reported immediately, as it suggests fluid retention and worsening heart failure that requires adjustment of diuretic therapy. Weekly weights are insufficient for early detection. Choice D rationale Nonsteroidal anti-inflammatory drugs (NSAIDs) like naproxen are generally contraindicated in heart failure. They can cause sodium and water retention, which exacerbates fluid overload, and they can impair renal perfusion, reducing the effectiveness of diuretics and increasing the risk of acute kidney injury. They should be avoided unless absolutely necessary. —.
