KROK 1 2020 – Question 84 · KROK (Medicine) · Pathophysiology
Decreased vasopressin synthesis causes polyuria and, as a result, marked dehydration. What is the mechanism of polyuria development?
- A. Decreased canalicular reabsorption of Na ions
- B. Decreased canalicular reabsorption of water
- C. Decreased canalicular reabsorption of proteins
- D. Decreased reabsorption of glucose
- E. Increased glomerular filtration
Hint
Ask which tubular process vasopressin regulates in the distal nephron, and what happens to urine volume and concentration when its signal is missing.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
