The nurse is caring for the client who has iron deficiency anemia. Which of the following instructions should the nurse include? Select all that apply.

Iron deficiency anemia occurs when the body has inadequate iron stores to produce sufficient hemoglobin for oxygen transport. Clients commonly present with fatigue, weakness, pallor, tachycardia, and exertional shortness of breath due to reduced oxygen-carrying capacity. Oral iron therapy with Ferrous sulfate is the standard treatment, but proper administration and dietary teaching are necessary to improve absorption and reduce adverse effects. Nursing education helps ensure effective treatment and prevention of recurrence. A. Increasing intake of milk and dairy products is not recommended when taking iron supplements because calcium interferes with iron absorption in the gastrointestinal tract. Dairy products can reduce the effectiveness of oral iron therapy if taken close to the medication time. The client should separate calcium-rich foods from iron administration. B. Taking an antacid within 30 minutes after medication administration is incorrect because antacids decrease gastric acidity, which is needed for optimal iron absorption. Reduced stomach acidity limits the conversion of iron into its absorbable form. Antacids should be avoided close to the time of iron supplementation. C. Taking the medication on an empty stomach is correct because iron is absorbed best in an acidic gastric environment without interference from food. Although some clients may need to take it with food if gastrointestinal upset occurs, the preferred teaching is to take it before meals for maximum absorption. D. Increasing sources of fiber in the diet is appropriate because iron supplements commonly cause constipation as a side effect. Adding fiber-rich foods such as fruits, vegetables, legumes, and whole grains helps promote bowel regularity and reduces discomfort associated with therapy. Adequate fluid intake should also be encouraged. E. Taking the medication with a source of vitamin C is correct because vitamin C enhances the absorption of non-heme iron by converting it into a more absorbable form. Drinking orange juice or consuming citrus fruits with iron supplements improves therapeutic effectiveness and supports correction of anemia.
