When reinforcing discharge teaching for a client with Cushing's syndrome, which statement indicates understanding of dietary management regarding potassium?

• A. I Can Eat Foods That Contain Potassium.
• B. I Will Need to Limit the Amount of Protein in My Diet.
• C. I Am Fortunate That I Can Eat All the Salty Foods I Enjoy.
• D. I Am Fortunate That I Do Not Need to Follow Any Special Diet.

Answer: (A)

Potassium balance is a key part of managing Cushing's syndrome because excess cortisol has mineralocorticoid-like effects that increase potassium loss in the kidneys, which can lead to hypokalemia. Because of this, including potassium-rich foods in the diet helps replace the losses and maintain normal potassium levels. Saying that you can eat foods containing potassium shows you understand this need and are taking steps to prevent low potassium.

The other statements miss this important point. Limiting protein doesn’t address potassium balance, enjoying salty foods isn’t about correcting potassium and can worsen fluid and electrolyte problems, and claiming no special diet is needed ignores the electrolyte shifts that can occur with cortisol excess.
