Urinary System Questions Questions
Question 1 of 5
A patients most recent laboratory findings indicate a glomerular filtration rate (GFR) of 58 mL/min. The nurse should recognize what implication of this diagnostic finding?
Correct Answer: D
Rationale: GFR of 58 mL/min (normal ~125 mL/min) indicates reduced filtration, raising serum creatinine (D). BUN increases, not decreases (A), potassium rises (not hypo, B), and voiding (C) isn't directly tied, making D the implication.
Question 2 of 5
The nurse is caring for a patient with a history of systemic lupus erythematosus who has been recently diagnosed with end-stage kidney disease (ESKD). The patient has an elevated phosphorus level and has been prescribed calcium acetate to bind the phosphorus. The nurse should teach the patient to take the prescribed phosphorus-binding medication at what time?
Correct Answer: D
Rationale: Both calcium carbonate and calcium acetate are medications that bind with the phosphate and assist in excreting the phosphate from the body, in turn lowering the phosphate levels. Phosphate-binding medications must be administered with food to be effective.
Question 3 of 5
The nurse performing the health interview of a patient with a new onset of periorbital edema has completed a genogram, noting the health history of the patients siblings, parents, and grandparents. This assessment addresses the patients risk of what kidney disorder?
Correct Answer: D
Rationale: PKD is a genetic disorder characterized by the growth of numerous cysts in the kidneys. Nephritic syndrome, acute glomerulonephritis, and nephrotic syndrome are not genetic disorders.

Question 5 of 5
Granular (juxtaglomerular cells) secrete ___ when there is a fall in ___ ion concentration.
Correct Answer: D
Rationale: Juxtaglomerular cells secrete renin (D) when sodium falls in the distal tubule, detected by the macula densa, activating RAAS. Chloride (A) is secondary, carbonic anhydrase (B) and ATPase (C) are unrelated, making D the trigger.
