Urinary System Questions Questions
Question 1 of 5
Along the Proximal Convoluted Tubules:
Correct Answer: C
Rationale: Proximal tubules reabsorb nearly all filtered glucose (100% normally), not secreted, partial (60-70%), or passively for amino acids (active). This distinguishes PCT's reabsorptive capacity, vital for nutrient retention, contrasting with secretion or partial views.
Question 2 of 5
The microscopic appearance of Magnesium Ammonium Phosphate (Struvite) is
Correct Answer: B
Rationale: Struvite (magnesium ammonium phosphate) crystals appear rectangular (coffin-lid shape) under microscopy classic infection stone marker (e.g., urease bacteria). Needle-shaped fits urate or cystine wrong chemistry. Amorphous lacks distinct form, unlike struvite's structure too vague. Hourglass isn't typical confuses with other forms. Rectangular morphology distinguishes struvite, key to identifying infection-driven stones, unlike sharp, shapeless, or misattributed shapes.
Question 3 of 5
Which of the following statement about Genito Urinary Tuberculosis (GUTB) is INCORRECT?
Correct Answer: D
Rationale: Optimal surgery for GUTB is 4-6 weeks post-therapy, not 1 week allows inflammation reduction, incorrect timing. GUTB is second to pulmonary in developing areas true prevalence. Kidney involvement is ~80% primary site. Urine AFB culture is gold standard specific diagnosis. Delayed surgery distinguishes correct management, key to balancing medical and surgical needs, unlike true epidemiology or diagnostics.
Question 4 of 5
Columns of Bertin are
Correct Answer: C
Rationale: Columns of Bertin are cortical extensions between medullary pyramids structural dividers, not medullary. Pyramid apex is papillary urine exit. Medullary extensions are pyramids themselves wrong tissue. Conical areas are pyramids, not columns shape error. Cortical columns distinguish them, key to renal architecture, unlike medullary or conical misplacements.
Question 5 of 5
Which form of incontinence is usually treated medically initially?
Correct Answer: D
Rationale: Urge incontinence is treated medically first antimuscarinics or β3-agonists calm detrusor overactivity, addressing urgency. Stress incontinence (leak with pressure) often needs surgery pelvic support issue. Continuous suggests fistula surgical. Overflow (retention) may need catheterization obstruction-based. Urge's detrusor focus distinguishes it, key to initial medical management, unlike structural or retention types.
