A nurse is providing dietary teaching for a client who has Cushing's disease. Which of the following recommendations should nurse include in the teaching?

A. Increase carbohydrate intake: In Cushing's disease, carbohydrate metabolism is often impaired, leading to increased blood glucose levels. Carbohydrate intake should generally be controlled, not increased. B. Restrict sodium intake: Cushing's disease can cause sodium retention and fluid retention due to excess cortisol. Restricting sodium helps control edema and high blood pressure. C. Limit intake of potassium-rich foods: Potassium levels can decrease in Cushing's disease due to the effects of cortisol, so potassium-rich foods should be encouraged to help counteract hypokalemia. D. Decrease protein intake: Protein intake should not be decreased in Cushing's disease. Excess cortisol can lead to protein catabolism and muscle wasting. Adequate protein intake is important to counteract this effect and support muscle mass and overall tissue integrity.
