Answer: D - A client with Cushing’s disease is at risk for hypokalemia. In this condition, the client secretes excessive amounts of cortisol, a steroid hormone, which causes the excretion of potassium. Clients on potassium-sparing drugs like spironolactone are at risk for hyperkalemia. Clients with chronic renal failure and Addison’s disease tend to accumulate potassium, as well.
