The home health care nurse is conducting a home visit with an older adult client who has a history of coronary artery disease, hypertension, and heart failure. The client has a new prescription for furosemide 40 mg PO daily. Which statement by the client indicates a correct understanding of taking this new medication safely?

A. "I will notify my doctor if my urine output increases after a few doses.": Diuresis is the intended pharmacological outcome for a patient with heart failure receiving loop diuretics. Increased urinary frequency and volume indicate that the medication is effectively reducing fluid overload. Reporting this expected finding would be an unnecessary use of clinical resources. B. "I will not eat my usual banana with my breakfast cereal in the morning.": Furosemide promotes the excretion of potassium in the distal tubule and the loop of Henle. Bananas are a high-potassium food that helps prevent the development of hypokalemia during diuretic therapy. Restricting dietary potassium while taking a non-potassium-sparing diuretic increases the risk of cardiac arrhythmias. C. "I will need to change positions slowly when going from laying down to sitting and then sitting to standing.": Rapid fluid volume reduction and vasodilation can lead to a significant drop in blood pressure upon standing. This orthostatic hypotension increases the risk of falls and syncope in older adult patients. Gradual transitions allow the body's baroreceptors to adjust and maintain adequate cerebral perfusion. D. "I will take my furosemide with a full glass of water just before bed time.": Administering loop diuretics in the evening results in nocturia, which disrupts the patient's sleep cycle and increases fall risks at night. Medication should be taken in the morning to allow for peak diuresis during waking hours. Timing the dose correctly is essential for maintaining patient safety and quality of life.
