A drug is classified as a diuretic (a drug that increases urination), is commonly used to lower blood pressure or eliminate the body of excess fluid. Most likely the drug:
Decreases the reabsorption of water
Decreases GFR (glomerular filtration rate)
Activates the renin-angiotensin-aldosterone system
Causes the release of ADH
The Correct Answer is A
A. Decreases the reabsorption of water: Most diuretics act by preventing the reabsorption of sodium and water in the nephron, increasing urine output.
B. Decreases GFR (glomerular filtration rate): Diuretics do not usually decrease GFR; some may slightly increase or maintain it.
C. Activates the renin-angiotensin-aldosterone system: Diuretics often reduce blood volume, which might trigger RAAS as a compensatory mechanism, but activation of RAAS is not the drug’s direct action.
D. Causes the release of ADH: Diuretics counteract the action of ADH by promoting diuresis.
