Which ONE of the following is not a cause of secondary hyperaldosteronism?

The answer is A. Adrenocortical adenomas may secrete excess aldosterone producing primary hyperaldosteronism.

Patients with hepatic cirrhosis with ascites (B), nephrotic syndrome (C) and cardiac failure (E) have retention of sodium and water (oedema), but the sodium is extravascular and so the kidney responds as in sodium deprivation.

Renal artery stenosis (D) results in a stimulus to renin release.
