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. Administer oral rehydration solution after each diarrheal stool: Oral rehydration solutions replace fluid and electrolytes lost during diarrhea and are the recommended treatment for children. Giving small, frequent amounts after each stool helps prevent dehydration. B. Encourage intake of carbonated beverages diluted with water: Carbonated drinks, even when diluted, are high in sugar and can worsen diarrhea by drawing more fluid into the intestines. They also lack the necessary electrolyte balance for proper rehydration. C. Provide the child with a bananas, rice, applesauce, and toast (BRAT) diet: The BRAT diet is no longer recommended for managing diarrhea in children because it is low in protein, fat, and essential nutrients. A normal diet with rehydration is more effective for recovery. D. Provide chicken or beef broth until the diarrhea subsides: Broths are high in sodium but lack adequate carbohydrate and potassium replacement. They do not provide balanced rehydration and may contribute to electrolyte imbalances if used alone.
