A nurse is providing discharge teaching to a client who has a new prescription for furosemide twice daily. The nurse should include which of the following instructions in the teaching? (select all that apply)

1) increase intake of potassium-rich foods 2) monitor for muscle weakness 3) dangle your legs from the side of the bed before standing "Take the second dose at bedtime" is incorrect. Furosemide is a loop diuretic that causes diuresis. When taken twice daily, the client should take the second dose of furosemide by 1400 hr to prevent nocturia."Increase intake of potassium-rich foods" is correct. Loop diuretics, such as furosemide, act at the loop of Henle by blocking the resorption of sodium, water, and potassium. An adverse effect of the medication is the development of electrolyte imbalances such as hyponatremia, hypochloremia, and hypokalemia. To prevent hypokalemia, the client should increase intake of potassium-rich foods, such as potatoes, spinach, dried fruit, and nuts."Obtain your weight weekly" is incorrect. Loop diuretics cause an increase in fluid excretion and can cause dehydration. While manifestations of dehydration, such as increased thirst and decreased urine output, can assist in the diagnosis of dehydration, the most reliable method of identifying the onset of dehydration is by loss of weight. The client should obtain daily weights to monitor for the diuresis effect of the medication."Monitor for muscle weakness" is correct. Furosemide, a loop diuretic, causes a loss of potassium, which can result in manifestations of hypokalemia such as difficulty concentrating, shallow respirations, hyporeflexia, and muscle weakness. The nurse should instruct the client to monitor for these manifestations and report them to the provider."Dangle your legs from the side of the bed before standing" is correct. Loop diuretics, such as furosemide, reduce vascular tone and increase fluid excretion. These effects decrease blood return to the heart and can manifest as dizziness and lightheadedness when going from a lying to a standing position. The client should change positions slowly to minimize orthostatic hypotension.
