What is the recommended management for mild to moderate dehydration due to gastroenteritis?

• A. Intravenous fluids only
• B. Oral rehydration therapy (ORS) with small, frequent sips and continued feeding.
• C. NPO with nothing by mouth
• D. Large-volume bolus of fluid without feeding

Answer: (B)

Managing mild to moderate dehydration from gastroenteritis relies on replacing fluids and electrolytes while keeping nutrition going. Oral rehydration therapy using a proper ORS is preferred, given in small, frequent sips so the child can tolerate it and vomiting is minimized. The glucose in ORS helps the intestines absorb sodium and water efficiently, speeding rehydration. At the same time, continue age-appropriate feeding to provide calories and support gut recovery; regular diet should be resumed as soon as the child can drink. Intravenous fluids are reserved for severe dehydration, ongoing dehydration despite oral fluids, or if the child cannot take fluids by mouth. Avoid NPO and avoid large-volume fluid boluses in this setting, as they don’t address the ongoing losses and can cause issues.
