A nurse is caring for a client who has cirrhosis and has a prescription for bumetanide. When delivering the client's lunch tray, which of the following items should the nurse identify as contraindicated for the client?

Rationale: A. Baked potato is low in sodium if prepared without added salt, making it safe for a client on a diuretic. B. Milkshake is generally safe unless it contains added sodium; in most cases, it is allowed. C. Ham is high in sodium, which is contraindicated for a client taking bumetanide, a loop diuretic, as high sodium intake can counteract the diuretic effect and worsen fluid retention. D. Stewed tomatoes can be included if unsalted; they are generally safe in moderation.
