Questions On The Urinary System Questions
Question 1 of 5
Cercarial Dermatitis (Bather's itch) caused by:
Correct Answer: A
Rationale: Cercarial dermatitis results from non-human schistosomes penetrating skin, not S. mansoni/haematobium (human parasites) or Trichomonas (STD). This distinguishes parasitic dermatitis, critical for epidemiology, contrasting with human-specific species.
Question 2 of 5
The hyperosmolarity of renal medulla is due to increase content of:
Correct Answer: D
Rationale: Medullary hyperosmolarity arises from Na+ and urea (countercurrent), not glucose or K+ alone. This defines concentration gradient, critical for urine concentration, contrasting with single solutes.
Question 3 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 4 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 5 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.
