Final answer:
The nurse should recommend offering gluten-free foods like brown rice, fruits, vegetables, meat, and beans to a child with celiac disease.
Step-by-step explanation:
When providing dietary teaching to the parent of a school-age child with celiac disease, the nurse should recommend offering foods that are gluten-free. Gluten is a protein found in wheat, barley, and rye, which can cause damage to the digestive system of individuals with celiac disease. Therefore, the parent should offer options like brown rice instead of white rice, as well as other gluten-free foods such as fruits, vegetables, meat, and beans.
