Urinary System Mcq Questions Questions
Question 1 of 5
If GFR is 125 ml/min.how much fluid our kidney filters in 24 hrs.
Correct Answer: A
Rationale: 125 mL/min × 1440 min = 180 L/day, not 160, 130, or 120. This calculates daily filtration, key for fluid dynamics, contrasting with underestimates.
Question 2 of 5
Which of the following statements concerning the ureters is false?
Correct Answer: D
Rationale: Ureters are retroperitoneal, not intraperitoneal (false), while epithelium, tunics, and peristalsis are true. This corrects ureter position, vital for anatomy, contrasting with true features.
Question 3 of 5
The triangular area of the urinary bladder between the two ureters posteriorly and the urethra anteriorly is the
Correct Answer: D
Rationale: Trigone is the bladder's triangular area (ureters to urethra), not sphincters or muscle (mislisted as D). This defines bladder base, vital for anatomy, contrasting with control structures.
Question 4 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 5 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.
