Answer to Question 1

ANS: A, B, E
Thiazide diuretics have the paradoxical effect of reducing urine output in patients with diabetes insipidus. They can also be used to mobilize edema associated with liver disease. They promote tubular reabsorption of calcium, which may reduce the risk of osteoporosis in postmenopausal women. Mannitol is used to treat edema that causes increased intracranial pressure and intraocular pressure.

Answer to Question 2

ANS: B
Spironolactone is a potassium-sparing diuretic used to counter the potassium-wasting effects of hydrochlorothiazide s. Patients taking potassium supplements are at risk for hyperkalemia when taking this medication, so they should be advised to stop the supplements. Spironolactone takes up to 48 hours to have effects. Salt substitutes contain high levels of potassium and are contraindicated. Spironolactone is a weak diuretic, so the risk of dehydration is not increased.
