What should the nurse advise a pregnant client to take with iron supplements to enhance absorption?

Taking iron supplements can sometimes be challenging due to potential issues with absorption. Vitamin C is known to enhance the absorption of iron, and orange juice is a good source of this vitamin. When a pregnant client consumes iron supplements alongside orange juice, the ascorbic acid present in the juice significantly improves the solubility and absorption of non-heme iron, which is the type commonly found in supplements and plant-based foods. This increased absorption is particularly important during pregnancy, as iron is essential for the increased blood volume and oxygen transportation needed to support both the mother and the developing fetus.

In contrast, other options such as milk and tea can inhibit iron absorption. Milk contains calcium, which competes with iron for absorption in the intestines. Tea, on the other hand, contains tannins that can bind to iron and hinder its absorption as well. Water does not have a significant effect on iron absorption, making it less beneficial in this context. Therefore, recommending orange juice is the most effective advice for enhancing iron absorption in a pregnant client.
