Urinary System Questions and Answers Questions
Question 1 of 5
What type of epithelium forms the lining of the proximal convoluted tubule? A) stratified squamous, B) transitional, C) simple ciliated columnar, D) simple cuboidal
Correct Answer: D
Rationale: The PCT has simple cuboidal epithelium (D) with microvilli for reabsorption. Stratified squamous (A) is in skin, transitional (B) in bladder, and ciliated columnar (C) in airways, making D correct.
Question 2 of 5
Which finding by the nurse for a patient admitted with glomerulonephritis indicates that treatment has been effective?
Correct Answer: C
Rationale: Resolved edema (C) shows treatment success in glomerulonephritis, as it reduces proteinuria and fluid retention. No dysuria (A) or nitrites (B) is expected (no UTI), and ASO titers (D) remain elevated post-infection, making C the key indicator.
Question 3 of 5
Which assessment finding for a patient who has just been admitted with acute pyelonephritis is most important for the nurse to report to the health care provider?
Correct Answer: C
Rationale: Low BP (88/45 mm Hg, C) suggests urosepsis or shock in pyelonephritis, a life-threatening emergency requiring immediate report. Foul urine (A), flank pain (B), and mild fever (D) are expected, but hypotension is critical, making C most urgent.
Question 4 of 5
The nurse is examining an adult patient. For what purpose would the nurse use palpation?
Correct Answer: C
Rationale: A distended bladder may be palpable above the symphysis pubis. Palpation would not be helpful in assessing for the other listed urinary tract information.
Question 5 of 5
The nurse is reviewing a patient's urinalysis results: white blood cells (WBC) 100+/hpf; red blood cells (RBC) 4/hpf; bacteria, moderate amount; nitrite, positive; specific gravity, 1.025; urine, cloudy. What would the nurse recognize these findings as indicating?
Correct Answer: B
Rationale: High WBCs, bacteria, positive nitrite, and cloudy urine (B) indicate a UTI. Dehydration (A) raises specific gravity alone, contamination (C, D) wouldn't consistently show nitrites, and RBCs are normal (0-4/hpf), making B the clear diagnosis.
