The nurse is providing teaching to the parents of a school-aged child newly diagnosed with Crohn's disease about dietary measures to implement during an exacerbation. Which statement made by the parents indicates a need for further instruction?

A. Consuming a diet high in iron-rich foods, such as lean meats, beans, and leafy vegetables, can help prevent iron deficiency anemia.

B. Regular consumption of fortified cereals provides essential nutrients, including iron, which can help prevent anemia.

C. This is the correct answer. Excessive intake of cow's milk can be a risk factor for iron deficiency anemia in toddlers because cow's milk is low in iron and can interfere with iron absorption. Additionally, consuming large amounts of cow's milk can cause gastrointestinal blood loss, further contributing to iron deficiency.

D. While participating in physical activities is important for a toddler's growth and development, it does not directly relate to an increased risk for iron deficiency anemia.

A. Administer an antiemetic before chemotherapy begins is the most appropriate action. Chemotherapy-induced nausea and vomiting can be anticipated, so administering an antiemetic before treatment helps to prevent these symptoms from occurring. This proactive approach is standard practice to manage chemotherapy side effects.

B. Encourage drinking large amounts of favorite fluids may help with hydration, but it doesn't specifically target nausea or vomiting. It’s better to focus on a strategy to directly prevent these symptoms, such as using antiemetics.

C. Offer frequent small meals before and after chemotherapy may help with general appetite and nutrition, but it doesn't directly address nausea and vomiting from chemotherapy.

D. Provide the child's favorite music as a distraction can be helpful for comfort but does not address the underlying issue of chemotherapy-induced nausea and vomiting.
