Urinary System Multiple Choice Questions Questions
Question 1 of 5
Which statement is true?
Correct Answer: D
Rationale: Both are true: High-dose furosemide lacks ARF benefit only aids overload (e.g., no GFR improvement). Dopamine (1-5 µg/kg/min, not mg) is renal-dose, used post-volume correction in oliguria unproven efficacy, but fits scenario. Dual accuracy distinguishes it, key to evidence-based ARF care, unlike single or negated options.
Question 2 of 5
Renal transplant patients should receive all of the following measures to prevent infection EXCEPT
Correct Answer: A
Rationale: MMR vaccine is contraindicated in transplant patients live attenuated, risks viremia in immunosuppression. Nystatin (candida), pneumococcal, and hepatitis B vaccines safe, recommended. Prophylaxis for dental procedures aligns standard. Live vaccine ban distinguishes it, critical for transplant safety, unlike protective measures.
Question 3 of 5
All of the following are risk factors for UTI EXCEPT
Correct Answer: D
Rationale: Irregular menses isn't a UTI risk unrelated to urinary tract (e.g., hormonal, not mechanical). Intercourse introduces bacteria proven. Uterine prolapse impairs emptying stasis. Diaphragm/spermicide alter flora E. coli growth. Lack of association distinguishes menses, key to risk factors, unlike mechanical/microbial triggers.
Question 4 of 5
During nucleotide biosynthesis, which of the following contribute to the structure of BOTH purines and pyrimidines?
Correct Answer: C
Rationale: Glutamine donates nitrogen to both purines (N3, N9) and pyrimidines (amide), unlike aspartic acid (purines), glutamic acid (indirect), or glycine (purines). This specifies nucleotide synthesis, key for DNA/RNA, contrasting with limited contributors.
Question 5 of 5
When GFR fall, the Na excretion will :
Correct Answer: A
Rationale: Decreased GFR reduces Na+ filtration, lowering excretion not increasing or unchanged. This links GFR to sodium handling, key for fluid balance, contrasting with compensatory misconceptions.
