Urinary System Questions and Answers Questions
Question 1 of 5
Concerning angiotensin II:
Correct Answer: A
Rationale: The RAAS involves liver angiotensinogen, renal renin, and endothelial ACE (A, true), but angiotensin II, not just aldosterone, stimulates thirst/appetite (B is false), and AII increases sodium reabsorption (C, true). Only A is unequivocally correct—system components are accurate—while B is wrong and C is partial, making A the answer.
Question 2 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 3 of 5
Aldosterone causes:
Correct Answer: D
Rationale: Aldosterone increases Na⺠reabsorption and K⺠secretion (D), reducing urine volume by retaining water. Decreased K⺠(A), increased Na⺠(B), or more output (C) oppose this, making D correct.
Question 4 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 5 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.
