Renal Exam Pharmacology Practice Test

Renal Exam Pharmacology Practice Test
Diuretic drugs increase urine output by the kidney by causing the kidney to:
A. Excrete less water
B. Excrete more sodium
C. Excrete less sodium - CORRECT ANSWERS-B

What is the most commonly used diuretics that inhibits the sodium-chloride transporter
in the distal convoluted tubule?
A. Loop Diuretics
B. Thiazide Diuretics
C. Potassium Sparing Diuretics - CORRECT ANSWERS-B (mechanism depends on
renal prostaglandin production)

Because sodium-chloride transporter normally
only reabsorbs about 5% of filtered
sodium, the thiazide diuretics are less
efficacious than which diuretics in producing diuresis and natriuresis.
A. Loop Diuretic
B. Potassium sparing diuretics - CORRECT ANSWERS-A

Which of the following is a common example of a thiazide diuretic?
A. Furosemide
B. Bumetanide
C. Hydrochlorothiazide
D. Amiloride - CORRECT ANSWERS-C

What is the most powerful diuretic that inhibits the sodium-potassium-chloride
cotransporter in the thick ascending limb of the loop of Henle?
A. Loop Diuretic
B. Potassium sparing diuretics
C. Thiazide Diuretics - CORRECT ANSWERS-A (most useful for Congestive Heart
Failure CHF)

sodium-potassium-chloride cotransporter normally reabsorbs what percentage of the
sodium load?
A. 15%
B. 25%
C. 35%
D. 45% - CORRECT ANSWERS-B (therefore, inhibition of this pump can lead to a
significant increase sodium and water excretion)

Renal Synthesis of prostaglandins is induced by which diuretic? (This increases renal
blood flow and redistribution of renal cortical blood flow)
