Diuretics Sherpath Questions And Correct
Answers Latest Version

Match the type of diuretic with its mechanism of action. ANS✔✔ Block
sodium and water reabsorption in the distal tubule:

Thiazide diuretics



Block sodium and chloride reabsorption in the loop of Henle:

Loop diuretics



Block sodium-potassium exchange in the collecting tubules:

Potassium-sparing diuretics



Why do loop diuretics have a greater diuresis effect than thiazides or
potassium-sparing diuretics?




Loop diuretics act directly by blocking sodium-potassium exchange in the
distal convoluted tubule.



Loop diuretics act early in the loop of Henle and block sodium chloride
reabsorption.



Loop diuretics block greater amounts of sodium chloride reabsorption in the
proximal convoluted tubule.

, Loop diuretics promote the greatest reabsorption of sodium chloride in the
loop of Henle. ANS✔✔ Loop diuretics act early in the loop of Henle and block
sodium chloride reabsorption.



Loop diuretics block the reabsorption of larger volumes of sodium and water
early in the loop of Henle to promote diuresis



Which action of a loop diuretic can potentially cause hypotension in patients
taking this medication?




Tubular reabsorption of sodium and chloride



Water retention and potassium-sparing



Excess fluid loss and dehydration



Decreased blood volume and venous constriction ANS✔✔ Decreased blood
volume and venous constriction



Loss of water and sodium reduces blood volume. Loop diuretics do not cause
smooth muscle constriction.



Why do patients taking thiazide diuretics have an increased risk for
hypercalcemia?




They promote GI absorption of calcium.
