A nurse is reinforcing discharge teaching to a client who has heart failure. Which of the following lifestyle modifications should the nurse include in the discharge teaching?

Choice A reason: Increased mobility is beneficial for general health but must be cautious in heart failure to avoid overexertion, which can exacerbate cardiac strain and fluid overload. Dietary and fluid restrictions are more critical to manage volume status, making mobility a secondary focus in discharge teaching for heart failure. Choice B reason: Dietary and fluid restrictions, particularly low-sodium diets and limited fluid intake, are essential in heart failure to reduce fluid overload, preload, and cardiac workload. This prevents exacerbations like pulmonary edema, making it a priority lifestyle modification to include in discharge teaching for effective heart failure management. Choice C reason: Cessation of intravenous drug use is relevant for specific populations but not a general heart failure management strategy. It does not directly address fluid overload or cardiac workload, unlike dietary and fluid restrictions, making it an incorrect focus for routine discharge teaching in heart failure. Choice D reason: Cessation of hormonal supplements is not typically relevant to heart failure management unless specific hormones affect fluid balance or cardiac function. Dietary and fluid restrictions directly address the pathophysiology of fluid overload, making this an incorrect lifestyle modification for routine heart failure discharge teaching.
