Urinary System Test Questions and Answers Questions
Question 1 of 5
Concerning urinary concentration:
Correct Answer: D
Rationale: The thick ascending loop creates the medullary gradient (A), urine entering the collecting duct is hypotonic post-dilution (B), and without ADH, water isn't reabsorbed, keeping urine dilute (C). All are true—gradient drives concentration, urine starts hypotonic, ADH is key—making E (all are correct), reassigned as D, correct.
Question 2 of 5
What type of epithelium forms the lining of the uterine (fallopian) tube? A) stratified squamous, B) transitional, C) simple ciliated columnar, D) simple cuboidal
Correct Answer: C
Rationale: The fallopian tube has simple ciliated columnar epithelium (C), aiding ovum transport. Stratified squamous (A) is in skin, transitional (B) in bladder, and cuboidal (D) in tubules, making C the match.
Question 3 of 5
The fluid in the capsular space is similar to plasma except that it does not contain a significant amount of:
Correct Answer: D
Rationale: Capsular filtrate lacks significant albumin (D) due to glomerular filtration barriers (podocytes, basement membrane) retaining proteins. Glucose (A), sodium (B), and H⺠(C) filter freely, making D the key difference.
Question 4 of 5
A 72-year-old who has benign prostatic hyperplasia is admitted to the hospital with chills, fever, and vomiting. Which finding by the nurse will be most helpful in determining whether the patient has an upper urinary tract infection (UTI)?
Correct Answer: D
Rationale: Costovertebral tenderness (D) indicates pyelonephritis (upper UTI), a critical finding with systemic symptoms like fever and chills. Suprapubic pain (A), distention (B), and foul urine (C) suggest lower UTI, less specific for upper tract involvement, making D most diagnostic.
Question 5 of 5
A patient with bladder cancer is scheduled for intravesical chemotherapy. In preparation for the treatment the nurse will teach the patient about
Correct Answer: D
Rationale: Emptying the bladder before intravesical chemotherapy (D) ensures direct drug contact with the bladder wall. Systemic effects like nausea (A), hair loss (B), or oral issues (C) don't occur with this local treatment, making D the key preparation.
