A nurse is contributing to the plan of care for an older adult client who takes furosemide daily. Which of the following interventions should the nurse include in the plan.

This scenario involves optimizing care for an older adult prescribed a loop diuretic. Knowledge of diuretic pharmacodynamics, fluid balance, age-related physiologic changes, and the prevention of fluid volume overload or electrolyte imbalances must be applied effectively. Choice A rationale Furosemide causes potassium depletion, but a serum potassium level of 5 mEq/L falls within the normal physiological range of 3.5 to 5.0 mEq/L. Withholding the medication is unnecessary and contraindicated without signs of hyperkalemia. Choice B rationale Loop diuretics rapidly inhibit sodium and fluid reabsorption in the loop of Henle, causing profound diuresis. Frequent toileting assistance accommodates urgency, prevents urinary incontinence, and reduces fall risks associated with orthostatic hypotension in older adults. Choice C rationale Fluid shifts from daily loop diuretics happen rapidly, requiring daily weight monitoring to detect acute changes. Monitoring weights weekly is insufficient to track immediate fluid volume alterations, heart failure exacerbations, or acute dehydration. Choice D rationale Restricting fluid intake to 500 mL daily is excessively restrictive and risks severe dehydration and prerenal acute kidney injury. Normal fluid requirements generally exceed this level unless severe, decompensated fluid retention dictates otherwise.
