Which food choice represents the best option for a client on a low-sodium diet?

Choosing a medium baked potato is the best option for a client on a low-sodium diet because it is naturally low in sodium and offers beneficial nutrients such as fiber, potassium, and vitamins. Whole, unprocessed foods like baked potatoes typically contain minimal sodium compared to packaged or processed options.

In contrast, processed cheese slices often contain significant amounts of sodium due to the additives used for flavor and preservation. Canned soup can be loaded with sodium as well, which is often used to enhance the taste, making it a poor choice for someone needing to limit sodium intake. Salted nuts, similarly, have additional sodium from the salt used in their preparation, which would not align with the goals of a low-sodium diet. Therefore, opting for a medium baked potato ensures that dietary restrictions are maintained while still providing a nutritious food choice.
