A nurse is obtaining a health history from a client. Which finding should the nurse identify as possible risk factors for iron deficiency anemia? Select all that apply
Explanation & Rationale
A. A high intake of red meat is actually a protective factor against iron deficiency anemia because red meat is a rich source of heme iron. Heme iron has a higher bioavailability and is absorbed more efficiently by the intestinal mucosa than non-heme iron found in plant sources. Therefore, a diet high in red meat would decrease rather than increase the risk of developing a depleted iron store in the body. B. Gastrointestinal bleeding is a primary cause of iron deficiency anemia in adults because it results in the chronic loss of hemoglobin-bound iron. Even occult blood loss from ulcers, diverticulosis, or malignancies can gradually deplete the body's iron reserves faster than they can be replenished through dietary intake. Identifying potential sites of blood loss is a critical step in diagnosing the underlying etiology of microcytic, hypochromic anemia. C. Current pregnancy significantly increases the physiological demand for iron to support the expansion of maternal red cell mass and the development of the fetus and placenta. If dietary intake or supplementation is insufficient to meet these elevated requirements, the mother is at high risk for gestational iron deficiency anemia. This state of increased demand is a well-recognized risk factor requiring routine monitoring of hemoglobin and ferritin levels during the prenatal period. D. A poor appetite often leads to inadequate dietary intake of essential nutrients, including iron, which is necessary for the synthesis of hemoglobin. Over time, a caloric or nutrient-restricted diet prevents the body from replacing the iron lost through normal cellular turnover and excretion. This risk factor is particularly common in geriatric populations or individuals with chronic illnesses where nutritional intake is compromised, leading to a gradual depletion of iron. E. While some vegetables contain non-heme iron, a low intake of vegetables is not as significant a risk factor for iron deficiency as the lack of animal proteins or the presence of active bleeding. Many individuals maintain adequate iron levels through other food groups, and the iron in vegetables is less easily absorbed than that found in meat. Therefore, focusing on vegetable intake alone is not a primary diagnostic indicator for this type of anemia.
