NCLEX Questions Urinary System Questions
Question 1 of 5
The preceptor is reviewing functions of the urinary system with the nursing student. What statement made by the nursing student would demonstrate correct understanding of functions of the urinary system?
Correct Answer: D
Rationale: Urea is indeed formed in the liver from protein metabolism and excreted by the kidneys (D), a correct urinary system function. EPO regulates red, not white, blood cells (A), renin release occurs with low pressure/flow (B), and low creatinine suggests healthy kidneys (C), making D the accurate statement.
Question 2 of 5
Renal ammonium ion excretion is increased by aldosterone, elevated blood pCOâ‚‚ and acidemia
Correct Answer: A
Rationale: Aldosterone, high pCOâ‚‚, and acidemia boost ammonium (NHâ‚„âº) excretion (A) in the collecting duct and proximal tubule to excrete H⺠during acidosis. Aldosterone enhances H⺠secretion, pCOâ‚‚ and acidemia stimulate ammoniagenesis, making A (true) correct over B or added options.
Question 3 of 5
What type of epithelium forms the lining of the vagina? A) stratified squamous, B) transitional, C) simple ciliated columnar, D) simple cuboidal
Correct Answer: A
Rationale: The vagina is lined with stratified squamous epithelium (A), protecting against friction. Transitional (B) is in the bladder, ciliated columnar (C) in fallopian tubes, and cuboidal (D) in tubules, making A correct.
Question 4 of 5
The ___ artery sits on the boundary between the cortex and the medulla of the kidney.
Correct Answer: C
Rationale: The arcuate artery (C) lies at the cortex-medulla junction, branching from interlobar arteries. Lobar (A) and interlobar (B) are deeper, and segmental (D) is proximal, making C the boundary vessel.
Question 5 of 5
Which information will the nurse include when teaching the patient with a urinary tract infection (UTI) about the use of phenazopyridine (Pyridium)?
Correct Answer: C
Rationale: Pyridium turns urine reddish-orange (C), a key teaching point for patient awareness. It's used short-term (not 7 days, A), doesn't require sunscreen (B), and isn't preventive pre-intercourse (D), making C the essential information.
