A nurse is caring for a child who has mild dehydration due to an Escherichia coli infection. Which of the following actions should the nurse take?

A. Giving small amounts of oral rehydration solution frequently helps to prevent dehydration without overwhelming the child's stomach. This method is effective in rehydrating the child gradually and is well tolerated. B. Fruit juices, especially those high in sugar, can worsen diarrhea and dehydration. They are not recommended for rehydration in cases of gastrointestinal infections. C. While bananas and rice are part of the BRAT diet and can be included in meals, they do not address the immediate need for rehydration as effectively as oral rehydration solutions. D. Promethazine is an antiemetic that is not typically indicated for mild dehydration and can have sedative side effects. Oral rehydration is the priority in managing mild dehydration.
