Questions On The Urinary System Questions
Question 1 of 5
All are characters of renal carcinoma, EXCEPT:
Correct Answer: B
Rationale: Renal cell carcinoma (RCC) invades veins early, has clear cells, causes hematuria, and affects adults not children (Wilms'). This corrects RCC epidemiology, vital for diagnosis, contrasting with pediatric tumors.
Question 2 of 5
Which of the following is NOT true about chronic renal failure:
Correct Answer: C
Rationale: Chronic renal failure (CRF) features hypertension, proteinuria progression, osteodystrophy, and hyperkalemia not hypokalemia (dyslipidemia true). This corrects electrolyte error, critical for CRF management, contrasting with hypokalemic states.
Question 3 of 5
With respect to glomerular filtration:
Correct Answer: A
Rationale: Glomerular filtration is passive ultrafiltration not unaffected by RBF (affects pressure) or 137 L/min (180 L/day). This corrects filtration mechanics, critical for GFR, contrasting with rate or flow errors.
Question 4 of 5
The kidneys are:
Correct Answer: D
Rationale: Kidneys regulate blood volume (water balance), pressure (RAAS), and pH (H+ excretion) all apply. This encompasses renal functions, vital for homeostasis, contrasting with single roles.
Question 5 of 5
The micturition reflex center is located in the:
Correct Answer: C
Rationale: Micturition reflex centers in sacral cord (S2-S4) not kidney, cerebrum, bladder, or hypothalamus. This locates reflex control, key for voiding, contrasting with higher/organ sites.
