Urinary System Mcq Questions Questions
Question 1 of 5
Which is not an absolute indication for dialysis in ARF?
Correct Answer: D
Rationale: Creatinine 1.0 mmol/L (~11.3 mg/dL) isn't an absolute dialysis indication level alone doesn't mandate it, unlike refractory hyperkalemia (>6.5 mmol/L, cardiac risk), pulmonary edema (fluid overload), or encephalopathy (uremic toxins), all urgent. Creatinine guides chronicity acute thresholds are symptom-driven. Lack of urgency distinguishes creatinine, critical for dialysis criteria (e.g., AEIOU: Acidosis, Electrolytes, Intoxication, Overload, Uremia), unlike life-threatening indications.
Question 2 of 5
Which is an correct statement regarding treatment of a torted appendix testis?
Correct Answer: A
Rationale: Torted appendix testis needs only analgesia self-limiting, resolves with pain control (e.g., NSAIDs), correct. Antibiotics are unnecessary no infection. Surgery isn't mandatory rarely needed. Local anesthetic isn't standard impractical. Analgesia's sufficiency distinguishes it, key to conservative management, unlike infection, surgical, or invasive errors.
Question 3 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 IVP (contrast) is outdated less sensitive.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 4 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 5 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.
