Renal System Questions Questions
Question 1 of 5

Correct Answer: B
Rationale: Avoidance of crowded places is characteristic of agoraphobia.
Question 2 of 5
The nurse contributes to the plan of care for a patient having an intravenous pyelogram. Which intervention should be included?
Correct Answer: B
Rationale: Monitoring creatinine detects contrast-induced kidney damage.
Question 3 of 5
Match the description 'Passively permeable to water' to the structure: A) proximal convoluted tubule, B) descending limb of the nephron loop, C) collecting duct, D) ascending limb of the nephron loop.
Correct Answer: B
Rationale: The descending limb (B) is passively permeable to water, allowing concentration via medullary osmosis. The proximal tubule (A) uses active sodium transport, collecting duct (C) requires ADH, and ascending limb (D) is impermeable, making B correct.
Question 4 of 5
The apical membrane of the proximal convoluted tubule cells is impermeable to bicarbonate ions.
Correct Answer: B
Rationale: The PCT apical membrane reabsorbs bicarbonate via Na+/H+ exchange and carbonic anhydrase, making it permeable (B), not impermeable (A). False reflects this active process, making B correct.
Question 5 of 5
Which of the following would NOT be secreted from the ISF into the filtrate?
Correct Answer: B
Rationale: Amino acids (B) are reabsorbed in the PCT, not secreted, to conserve nutrients. Organic acids (A), bases (C), and creatinine (D) are secreted to eliminate waste, making B the exception.
