Question

diuretics ________ .
a decrease water reabsorption
b raise blood volume
c increase urine flow
d both decrease water reabsorption and increase urine flow

Explanation:

Diuretics work by reducing water reabsorption in the kidneys, which in turn leads to an increase in urine flow. Option A is part of the mechanism, option C is the result, and option D combines both the mechanism (decrease water reabsorption) and the result (increase urine flow), which is correct. Option B is incorrect as diuretics typically decrease blood volume by increasing fluid loss.

Answer:

D. both decrease water reabsorption and increase urine flow
