a. Decreased blood volume
b. Decreased blood K+ levels
c. Increased urine Na+ levels
d. Increased white blood cells
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.
