A nurse is providing dietary teaching for a client who has a burn injury and adheres to a vegan diet. The nurse should recommend which of the following foods as the best source of protein to promote wound healing?

The correct answer is C: One cup of lentils. Lentils are a great source of plant-based protein, essential for wound healing. They are also rich in iron, which is important for oxygen transport to promote tissue repair. Brown rice (A) lacks sufficient protein for wound healing. Orange juice (B) is high in vitamin C but lacks protein. Avocado (D) is a good source of healthy fats but low in protein. In summary, lentils provide the necessary protein and nutrients for wound healing, making them the best choice in this scenario.
