What is the standard field approach to dehydration management in pediatric patients?

• A. IV fluids for all dehydration cases
• B. Oral rehydration solution only
• C. No fluids
• D. Oral rehydration solution if possible; IV fluids for severe dehydration

Answer: (D)

In pediatric dehydration, the best approach in the field is to start with oral rehydration solution whenever the child can drink and is not in shock. ORS is designed to replace water, electrolytes, and glucose, promoting intestinal absorption and rehydration in a safe, simple way that doesn’t require IV access. However, if the child shows signs of severe dehydration or is unable to take fluids by mouth—due to vomiting, lethargy, or poor perfusion—rapid IV fluids are needed to quickly restore circulating volume and perfusion. After stabilization, fluid management can transition back to ORS for ongoing rehydration as appropriate. The other options miss the nuance of severity and practicality in a field setting.
