Answer to Question 1

ANS: A
ADH increases water permeability and reabsorption in the last segment of the distal tubule and along the entire length of the collecting ducts. ANP inhibits secretion of renin, inhibits angioten-sin-induced secretion of aldosterone, relaxes vascular smooth muscle, and inhibits sodium and water absorption by kidney tubules. Renin is secreted to raise blood pressure. Aldosterone regu-lates water and sodium balance.

Answer to Question 2

ANS: A
Hypokalemia is a side effect of diuretics. Hypokalemia, not hyponatremia, is a side effect of di-uretic therapy. Diuretics promote uric acid retention, not excretion. Hypokalemia is a side effect of diuretics. Hypermagnesemia is not.
