KROK 1 2010 – Question 72 · 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. Reduction of atrial natriuretic factor
- D. Vasopressin increase
- E. Vasopressin reduction
Hint
Think about how a sudden rise in extracellular volume and osmolality alters the renin-angiotensin axis, and what that does to sodium handling in the distal tubule.
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.
