Which scenario most clearly requires evacuation?

• A. A minor burn on the hand treated with water and dressing.
• B. An abdominal injury with tenderness, guarding, distention, and signs of shock out of proportion.
• C. Asthma attack controlled by a quick-acting inhaler.
• D. Hypoglycemia resolved after sugary drink.

Answer: (B)

In wilderness care, the decision to evacuate hinges on identifying signs of a potentially life-threatening injury that can deteriorate quickly, requiring definitive care beyond the field.

Abdominal injury with tenderness, guarding, and distention points to possible internal organ damage and bleeding. When these findings are accompanied by signs of shock that are out of proportion to the exam—such as a rapid pulse, pale or cool skin, or mental status changes—it suggests that internal injury is actively affecting circulation and could worsen without urgent treatment. This scenario carries a high risk of rapid deterioration, so rapid evacuation to a facility with surgical capabilities is the safest course.

The other situations are more stable or easily managed on scene. A small burn treated with cooling and dressing is a local wound issue without immediate need for transport. An asthma attack that responds to a quick-acting inhaler can often be managed with the inhaler, with reassessment and transport only if symptoms recur or worsen. Hypoglycemia that improves after a sugary drink has been corrected and stabilized, and while monitoring is prudent, does not by itself mandate immediate evacuation.

So, the scenario with abdominal signs and disproportionate shock is the one that clearly requires evacuation due to the high risk of internal injury and rapid potential deterioration.
