For burns up to 30% TBSA in a conscious patient who can swallow, which hydration method is recommended?

• A. Intravenous lactated Ringer's only
• B. Intramuscular fluids
• C. Oral fluids
• D. Submersion in clean water

Answer: (C)

When a burn is up to about a third of body surface area and the patient is conscious and able to swallow, oral rehydration is appropriate in the field. Burns cause fluid loss through the skin and inflammatory responses, so replacing fluids is important, but this scenario allows safe, noninvasive rehydration with an electrolyte solution. Start with small sips and progress as tolerated, watching for vomiting. This approach avoids the delays and complications of IV access in austere conditions and provides both water and electrolytes to support circulatory needs.

Intravenous fluids are more appropriate when the patient cannot take fluids, shows signs of shock or poor perfusion, or the burns are large and require rapid resuscitation. Intramuscular administration isn’t a reliable method for hydration in this context, and submersion in clean water does not provide controlled rehydration and poses risks like hypothermia and infection.
