A nurse is providing prenatal teaching about iron to a client who follows a vegetarian diet. The nurse should recommend that the client consume which of the following foods to enhance the absorption of nonheme iron?

A. Boiled eggs: While eggs contain some iron, the iron is nonheme and not highly absorbable. Eggs do not contain vitamin C, which is necessary to enhance nonheme iron absorption. B. Mixed nuts: Nuts provide nonheme iron but lack significant vitamin C, so consuming them alone does not significantly improve absorption. They are beneficial for iron intake but not for enhancing absorption. C. Cheddar cheese: Dairy products contain very little iron and can actually inhibit nonheme iron absorption when consumed with iron-rich foods, making them a less effective choice for enhancing iron uptake. D. Orange slices: Vitamin C in oranges significantly enhances the absorption of nonheme iron from plant-based sources. Consuming foods rich in vitamin C alongside iron-rich plant foods is an effective strategy for clients following a vegetarian diet.
