A nurse is planning a diet for a client who is iron deficient. Which of the following foods high in iron should the nurse include in the plan?

The correct answer is D: Red meat. Red meat is a high source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like cashews, oranges, and yogurt. Heme iron from red meat can help increase the client's iron levels more effectively. Cashews, oranges, and yogurt are good sources of non-heme iron, but they are not as efficient in boosting iron levels as red meat. Therefore, including red meat in the client's diet plan is crucial for addressing iron deficiency.
