KROK 1 2021 – Question 13 · KROK (Medicine) · Pathophysiology
A man presents with decreased vasopressin synthesis, which causes polyuria and results in marked dehydration. What is the most likely polyuria mechanism in this case?
- A. Decreased tubular reabsorption of protein
- B. Decreased tubular reabsorption of water
- C. Increased hydrostatic pressure
- D. Disturbed glucose reabsorption
- E. Disturbed tubular reabsorption of Na ions
Hint
Recall what vasopressin normally does to the permeability of the collecting ducts through aquaporin channels, and what happens when it is missing.
