Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Which one of the following compounds cannot give rise to the net synthesis of Glucose?
Correct Answer: B
Rationale: Gluconeogenesis uses lactate, α-ketoglutarate, and glycerol not acetyl CoA (enters Krebs, no net glucose). This distinguishes gluconeogenic substrates, key for fasting metabolism, contrasting with irreversible pathways.
Question 2 of 5
The most common genetic cause for male infertility is
Correct Answer: C
Rationale: 47 XXY (Klinefelter syndrome) is the most common genetic male infertility cause extra X disrupts spermatogenesis, causing azoospermia. 47 XYY (Jacob's) rarely affects fertility normal testes. 45 XO (Turner's) is female, not male irrelevant. 46 XY is normal male karyotype no infertility link. Klinefelter's chromosomal excess distinguishes it, critical for genetic infertility, unlike rare, female, or normal variants.
Question 3 of 5
The Substrate for NOS (Nitric Oxide Synthase)
Correct Answer: A
Rationale: L-Arginine is the substrate for NOS converted to nitric oxide (NO) and citrulline, key for vasodilation (e.g., erection). Citrulline is a product, not substrate resultant. Cyclic AMP/GMP are second messengers, not NOS inputs downstream. Arginine's conversion distinguishes it, critical for NO production, unlike products or signaling molecules.
Question 4 of 5
A 34 year male has road traffic accident. His vital signs are stable and there are no significant external injuries. CT scan revealed deep parenchymal lacerations in the right kidney. The next step is
Correct Answer: C
Rationale: Delayed imaging assesses pelvicalyceal integrity (e.g., urine leak) in stable deep lacerations guides conservative vs. intervention. Open repair risks unnecessary surgery stability favors watching. Embolization suits vascular injury, not parenchymal mismatch. Nephrectomy is extreme preservation priority. Delayed imaging distinguishes it, key to defining injury extent, unlike premature or radical steps.
Question 5 of 5
The current indications for sacral neuromodulation include all except
Correct Answer: C
Rationale: Sacral neuromodulation treats urgency, frequency, and urge incontinence modulates sacral nerves (S3) for bladder control. Interstitial cystitis (IC) isn't a standard indication pain-focused, variable response, not primary use. Urgency/frequency tie to overactivity responsive. Urge incontinence is core strong evidence. IC's exclusion distinguishes it, critical for neuromodulation's scope, unlike included overactive symptoms.
