Which of the following treatments is most appropriate for a child with severe diarrhea and no dehydration?

Providing oral rehydration solution (ORS) at home is the most appropriate treatment for a child with severe diarrhea who is not dehydrated. ORS is specifically formulated to replace lost fluids and electrolytes in children experiencing diarrhea, even if they are not showing signs of dehydration. It is effective and easy to administer at home, allowing parents to manage the child’s symptoms without the need for hospitalization or more invasive treatments.

In cases of severe diarrhea without dehydration, the use of ORS helps to prevent potential dehydration from continuing fluid losses. It encourages the child to drink fluids that are both hydrating and contain vital salts, making it a practical and safe choice for outpatient management.

Other options like immediate hospitalization and starting intravenous fluids are typically reserved for cases where there are signs of severe dehydration or other complicating factors that warrant closer medical supervision. Providing solid foods only would not address the primary goal of rehydration needed in this situation and could lead to further gastrointestinal distress without addressing fluid and electrolyte loss. Therefore, the recommendation to use ORS at home caters to the child’s current condition and ensures proper hydration management.
