A nurse is caring for a toddler who drinks 946 mL (32 oz) of whole milk per day and has a poor appetite. The nurse should identify the toddler as being at risk for which of the following conditions?

A. Iron deficiency anemia Whole milk is low in iron and can interfere with iron absorption. Excessive milk intake can also displace iron-rich foods from the diet, increasing the risk of iron deficiency anemia. B. Vitamin A toxicity Vitamin A toxicity is usually caused by over-supplementation, not milk intake. Milk does contain vitamin A, but not in levels high enough to cause toxicity in this context. C. Impaired carbohydrate metabolism There is no link between drinking whole milk and impaired carbohydrate metabolism. This would be more associated with inborn errors of metabolism. D. Lactose intolerance Lactose intolerance presents with gastrointestinal symptoms (bloating, diarrhea, etc.) after consuming dairy, not poor appetite. Also, toddlers with lactose intolerance typically avoid milk due to discomfort.
