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.

Correct Answer is D
Explanation
A. “This test will inform your provider if you are anemic.” Hemoglobin and hematocrit levels are used to assess anemia, not creatinine.
B. “This test will inform your provider if you have a thyroid disorder.” TSH and T3/T4 levels assess thyroid function, not creatinine.
C. “This test will inform your provider if you have an infection.” Infection is usually assessed by WBC count, CRP, or cultures, not creatinine.
D. “This test will inform your provider how your kidneys are functioning.” Serum creatinine is a reliable indicator of renal function; it reflects the kidney’s ability to clear waste.
Correct Answer is ["A","B","E"]
Explanation
A. Reabsorption: The nephron reabsorbs water, glucose, and electrolytes from the filtrate back into the blood.
B. Filtration: The glomerulus filters blood, initiating urine formation by removing waste, water, and solutes.
C. Storage: Urine storage occurs in the bladder, not the nephron.
D. Increase RBC production: While the kidneys release erythropoietin, which stimulates RBC production, this is not a nephron-specific function.
E. Secretion: The nephron actively secretes waste products like hydrogen ions and drugs into the tubule for excretion.
