Urinary System Test Questions and Answers Questions
Question 1 of 5
A client with dissociative identity disorder (DID) is being assessed. The nurse understands that the primary cause of DID is:
Correct Answer: B
Rationale: Dissociative identity disorder is strongly linked to severe childhood trauma.
Question 2 of 5
A patient hourly urine output is recorded. Which output rate should be reported immediately?
Correct Answer: A
Rationale: Urine output below 30 mL/hr indicates potential kidney dysfunction.
Question 3 of 5
Most reabsorption of substances from the glomerular filtrate occurs in the:
Correct Answer: C
Rationale: The proximal convoluted tubule (PCT) (C) reabsorbs ~65% of glomerular filtrate, including water, glucose, and ions, due to its microvilli and carrier proteins. The glomerulus (A) filters, not reabsorbs, the collecting tubule (B) adjusts urine concentration, and the ureter (D) transports urine, making C the primary reabsorption site.
Question 4 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 5 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.
