One Important Distinction with Potassium-Sparing Diuretics Over Other Forms of Diuretics

One important distinction with potassium-sparing diuretics over other forms of diuretics is that potassium-sparing diuretics:

A) exert their effects early in the nephritic process.
B) are more efficient than loop diuretics in sodium and water reabsorption.
C) not only decrease sodium reabsorption, they increase potassium reabsorption.
D) are so potent that they are rarely used with other diuretics.
