Step-by-step explanation:
The nurse should encourage the client with iron-deficiency anemia to increase her consumption of all the following foods: 1) Red meat, 2) Leafy green vegetables, and 3) Citrus fruits. Red meat is a good source of heme iron, which is absorbed more efficiently by the body compared to non-heme iron found in plant foods. Leafy green vegetables provide non-heme iron and other vitamins like vitamin A and folic acid. Citrus fruits are rich in vitamin C, which enhances iron absorption from the intestine, making the iron from other foods more bioavailable.
