A patient is diagnosed with Cushing's disease. Which statement about hyperaldosteronism is correct?

Steroid injections will be administered daily

Weight gain and edema are present.

Painful leg cramps are common from hyperkalemia.

Decreased amount of body hair is frequently seen.

Answer and Explanation

The Correct Answer is B

A. Steroid injections will be administered daily: This is incorrect; steroid therapy may exacerbate Cushing's disease. The condition is often due to excessive production of cortisol, not a deficiency.

B. Weight gain and edema are present: Hyperaldosteronism, often associated with Cushing's syndrome, leads to sodium and water retention, resulting in weight gain and edema.

C. Painful leg cramps are common from hyperkalemia: Hyperaldosteronism typically causes hypokalemia, not hyperkalemia, leading to muscle cramps, not leg pain from hyperkalemia.

D. Decreased amount of body hair is frequently seen: Cushing's disease often leads to hirsutism (increased body hair), not a decrease.
