Which nutrient should the nurse include in educating parents of an anemic adolescent regarding diet?

Folic acid is crucial for adolescents, especially those experiencing anemia, because it plays a significant role in the production of red blood cells. It is a B-vitamin that helps in the synthesis of DNA and is vital for cell division, which is especially important during periods of rapid growth such as adolescence. Anemia can often be related to a deficiency in folate, leading to a decrease in red blood cell production, which in turn can cause fatigue and weakness.

Including folic acid in the diet can help improve hemoglobin levels and support overall health. Foods rich in folate include leafy greens, legumes, nuts, and fortified cereals. Educating parents on the importance of incorporating these foods into their adolescent's diet can help in managing and potentially resolving anemia.

Calcium, thiamine, and riboflavin are also important nutrients, but they do not directly address the specific needs associated with anemia as effectively as folic acid does.
