A nurse in a pediatric clinic is caring for a child who has iron deficiency anemia and is to start taking ferrous sulfate syrup. Which of the following instructions should the nurse give the parent?

A. Dilute the medication with 240 mL (8 oz) of milk. Milk can inhibit iron absorption, so it's not recommended to mix iron supplements with milk. B. Administer the medication at meal time. Iron supplements are best absorbed when taken with food, specifically vitamin C-rich foods to enhance absorption. This instruction promotes optimal therapeutic effect. C. Administer the medication at bedtime: Timing with meals is more effective than at bedtime. D. Offer the medication through a straw. The method of administration is less critical than the timing with meals.
