A nurse is providing teaching to the guardian of a school-age child who has acute diarrhea. Which of the following instructions should the nurse include in the teaching?

A. Provide the child with a bananas, rice, applesauce, and toast (BRAT) diet: While the BRAT diet was traditionally recommended, it is now discouraged because it is low in calories, protein, and other nutrients essential for recovery. A balanced diet with regular foods is preferred. B. Provide chicken or beef broth until the diarrhea subsides: Broth alone lacks adequate calories, protein, and electrolytes needed for proper nutrition and hydration during diarrhea. C. Encourage intake of carbonated beverages diluted with water: Carbonated and sugary drinks can worsen diarrhea and contribute to dehydration due to high sugar content and carbonation. D. Administer oral rehydration solution after each diarrheal stool: Oral rehydration solutions contain the appropriate balance of electrolytes and fluids to replace losses and prevent dehydration, making them the most effective intervention during acute diarrhea episodes.
