Answer to Question 1

ANS: C
Long-term potassium deficits lasting more than 1 month may damage renal tissue, with interstitial fibrosis and tubular atrophy. Long-term potassium deficits are not associated with damage to the CNS, GI tract, or lungs.

Answer to Question 2

ANS: B
Aldosterone is secreted from the adrenal cortex. It promotes renal sodium and water reabsorption and excretion of potassium, leading to decreased potassium levels. Blood volume actually in-creases with aldosterone secretion. Aldosterone promotes sodium reabsorption, leading to normal or decreased Na+ levels, and is not associated with white blood cells.
