A parent tells a nurse that her toddler drinks a quart of milk daily and has a poor appetite for solid foods. The nurse should explain which disorders the toddler is at risk for.

A. Obesity: Excessive milk intake can contribute to excessive calorie consumption, but drinking a quart of milk alone without other dietary factors is less directly linked to obesity in toddlers. B. Diabetes mellitus: There is no direct evidence that high milk intake in toddlers causes diabetes mellitus. This condition is influenced by genetic and environmental factors unrelated to milk consumption alone. C. Iron deficiency anemia: Drinking excessive milk can lead to iron deficiency anemia because milk is low in iron and can interfere with iron absorption. When toddlers consume too much milk, they may have a poor appetite for iron-rich solid foods, increasing their risk of developing anemia. D. Rickets: Rickets results from vitamin D deficiency and calcium imbalance. Since milk is typically fortified with vitamin D and calcium, excessive milk intake usually reduces rather than increases the risk of rickets, making this less likely in this scenario.
