Which of the following is TRUE concerning glomerular function?

A.

An increase in GFR (glomerular filtration rate) increases urine formation

B.

It is not an indication of kidney function

C.

A decrease in GFR (glomerular filtration rate) causes polyuria (increase in urination)

D.

It is unaffected by blood pressure

Answer and Explanation

The Correct Answer is A

A. An increase in GFR increases urine formation: A higher GFR means more plasma is filtered, leading to more urine production.

B. It is not an indication of kidney function: GFR is a primary indicator of kidney function.

C. A decrease in GFR causes polyuria: A low GFR usually leads to oliguria (low urine output), not polyuria.

D. It is unaffected by blood pressure: GFR is directly influenced by blood pressure; low pressure decreases filtration.

Correct Answer is A

Explanation

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.
