KROK 1 2011 – Question 80 · KROK (Medicine) · Physiology
A concentrated solution of sodium chloride was intravenously injected to an animal. This caused decreased reabsorption of sodium ions in the renal tubules. It is the result of the following changes of hormonal secretion:
- A. Aldosterone increase
- B. Aldosterone reduction
- C. Vasopressin reduction
- D. Vasopressin increase
- E. Reduction of atrial natriuretic factor
Hint
A hypertonic saline load expands the extracellular volume; ask how the renin-dependent hormonal axis responds and what that does to distal sodium retention.
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.
