A nurse is caring for a client who has a new prescription for ferrous sulfate tablets twice daily for iron-deficiency anemia. The client asks the nurse why the provider instructed that she take the ferrous sulfate between meals. Which of the following responses should the nurse make?

A. Taking ferrous sulfate between meals may actually help reduce the risk of constipation, but this is not the primary reason for timing. B. Taking the medication with food does not typically increase the risk of esophagitis; rather, it can decrease the absorption of iron. C. Taking ferrous sulfate between meals allows for optimal absorption of iron, as food can interfere with its absorption. This response accurately explains the rationale for the timing of the medication. D. While it is true that some patients may experience nausea when taking iron supplements with food, the primary reason for taking it between meals is to enhance absorption rather than to prevent nausea.
