A nurse in a provider's office is caring for a client. Exhibits The nurse is educating the client on how to take iron supplements. Which of the following statements should be included in the teaching? Select all that apply

A. Take the medication with a source of vitamin C: Vitamin C (e.g., orange juice, strawberries) enhances absorption of iron. It converts ferric iron to a more easily absorbed ferrous form. B. Increase intake of milk and dairy products: Dairy products contain calcium, which inhibits iron absorption. Clients should avoid taking iron with milk or within 1–2 hours of calcium-rich foods. C. Take an antacid within 30 min after medication administration: Antacids decrease absorption of iron by increasing gastric pH. They should be avoided or taken at least 2 hours apart from iron. D. Take the medication on an empty stomach: Iron is best absorbed when taken 1 hour before meals or 2 hours after. Food, especially calcium, whole grains, and tea, reduces absorption. E. Increase sources of fiber in the diet: Oral iron supplements commonly cause constipation. Increasing dietary fiber, fluid intake, and activity helps prevent this side effect.
