A nurse is reinforcing teaching with a client who has an electrolyte imbalance. Which of the following foods should the nurse include as the lowest in potassium?

A. Wheat bread: Wheat bread is relatively low in potassium compared with fruits, vegetables, and juices. It is generally appropriate for clients who require potassium restriction due to renal disease or certain electrolyte imbalances. B. Orange juice: Orange juice is high in potassium and can significantly increase serum potassium levels. It is commonly restricted in clients who must limit potassium intake to prevent hyperkalemia. C. Sweet potato: Sweet potatoes contain a high amount of potassium, especially when baked or mashed. They are typically avoided in low-potassium diets because they can rapidly elevate potassium levels. D. Canned green beans: Although canned vegetables have less potassium than fresh ones due to processing, green beans still contain more potassium than wheat bread. They are not the lowest potassium option.
