Urinary System Mcq Questions Questions
Question 1 of 5
For what length of time should a man with a UTI be treated for?
Correct Answer: D
Rationale: Men with UTI need 10-14 days of treatment higher risk of complicated infection (e.g., prostate involvement), requiring longer courses. 3-5 days suit uncomplicated female cystitis insufficient here. 7 days is intermediate under-treats potential complexity. 10-14 days distinguishes it, critical for male UTI clearance, unlike shorter female-focused durations.
Question 2 of 5
Which is the imaging modality of choice in suspected renal haematuria?
Correct Answer: B
Rationale: Non-contrast CT is the choice for renal hematuria detects stones, masses, trauma (~95% sensitivity), fast/accurate. IVP (contrast) is outdated less sensitive. Angiography targets vessels not broad hematuria. Ureteroscopy is invasive diagnostic, not first-line. CT's versatility distinguishes it, key to hematuria workup, unlike older, specific, or procedural options.
Question 3 of 5
Which is not a principal of treatment in ATN due to rhabdomyolysis?
Correct Answer: D
Rationale: Aiming for pH <6 isn't treatment for rhabdomyolysis ATN alkalinization (pH >6.5) prevents myoglobin casts, incorrect. Hyperkalemia correction cardiac safety, true. Saline for hypovolemia restores perfusion, correct. Diuretics (furosemide/mannitol) flush tubules standard. Acidic goal distinguishes the error, key to myoglobin management, unlike supportive principles.
Question 4 of 5
A 1 mm renal calculi in the ureter will most likely impact at
Correct Answer: B
Rationale: A 1 mm ureteral stone most likely impacts at the vesico-ureteric junction (VUJ) narrowest point (2-3 mm), distal bottleneck. Pelvi-ureteric junction (PUJ) and pelvic brim catch larger stones less for 1 mm. Bladder orifice is post-ureter irrelevant. VUJ's constriction distinguishes it, key to small stone obstruction, unlike proximal or irrelevant sites.
Question 5 of 5
A 19-year-old male complains of acute onset of scrotal pain. Which of the following procedures is LEAST indicated?
Correct Answer: A
Rationale: Treating with cefixime/azithromycin (STD regimen) and discharging is least indicated acute scrotal pain suggests torsion, a surgical emergency, not epididymitis. Radionuclide scan/Doppler confirm torsion useful. Manual detorsion relieves attemptable. Urinalysis rules out infection relevant. Presumptive antibiotics distinguish the error, key to missing torsion, unlike diagnostic or therapeutic steps.
