NCLEX Questions for Urinary System Questions
Question 1 of 9
Concerning the transport of urea in the different segments of the nephron:
Correct Answer: D
Rationale: Urea enters via filtrate (A), concentrates in cortical collecting ducts as water exits (B), and thin loops/medullary ducts allow urea recycling (C). All are true—filtrate supplies urea, water reabsorption concentrates it, permeable segments recycle it—making E (all are correct), reassigned as D, correct.
Question 2 of 9
A 79-year-old man has been admitted with benign prostatic hyperplasia. What is most appropriate to include in the nursing plan of care?

Question 3 of 9
The nurse is reinforcing teaching of the most serious side effect of peritoneal dialysis. Which of these if stated by a patient indicates correct understanding?
Correct Answer: C
Rationale: A major complication of peritoneal dialysis is peritonitis which can be life threatening.
Question 4 of 9
Which part of the Loop of Henle is more permeable to water?
Correct Answer: B
Rationale: The thin descending limb of the Loop of Henle is highly permeable to water due to its numerous aquaporin-1 channels, allowing water to exit into the hyperosmotic medullary interstitium, concentrating the filtrate. The thick ascending limb actively reabsorbs Na⺠and Cl⻠but is impermeable to water, diluting the filtrate. The thin ascending limb has limited water permeability, and there's no ‘thick descending limb,' making B the correct answer.
Question 5 of 9
The nurse is caring for a patient who is receiving furosemide (Lasix) and an aminoglycoside antibiotic. The nurse will be most concerned if the patient reports which symptom?
Correct Answer: D
Rationale: Tinnitus signals ototoxicity, a risk when combining furosemide and aminoglycosides.
