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?

Choice A reason: Encouraging fruit juices is not the best approach for rehydration in a child with mild dehydration. Fruit juices can be high in sugar and may worsen diarrhea. Choice B reason: Giving oral rehydration solution in small, frequent amounts is the recommended treatment for mild dehydration due to infection. This helps replace lost fluids and electrolytes. Choice C reason: Promethazine is not indicated for the treatment of dehydration. It is an antihistamine and antiemetic, but it does not address the underlying issue of fluid loss. Choice D reason: Offering banana and rice can be part of a bland diet after rehydration, but it does not address the immediate need for replenishing lost fluids and electrolytes. The priority is to start with oral rehydration solution.
