Which of the following is TRUE concerning glomerular function?
An increase in GFR (glomerular filtration rate) increases urine formation
It is not an indication of kidney function
A decrease in GFR (glomerular filtration rate) causes polyuria (increase in urination)
It is unaffected by blood pressure
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 C
Explanation
A. Causes albuminuria: Albuminuria (protein in urine) is a sign of kidney damage, not a direct effect of RAAS activation.
B. Reabsorbs K⁺ and eliminates Na⁺ in the urine: RAAS does the opposite-it reabsorbs sodium and excretes potassium.
C. Expands blood volume, increasing blood pressure: RAAS activation leads to vasoconstriction and sodium/water retention, which raises blood pressure.
D. Causes hematuria: Hematuria (blood in urine) is typically a sign of trauma, infection, or kidney disease-not directly linked to RAAS.
Correct Answer is C
