Which statement is NOT a typical evacuation criterion from a field medical unit?

• A. Deterioration without improvement
• B. Stable vitals for 24 hours
• C. Uncontrolled hemorrhage
• D. Need for surgical intervention

Answer: (B)

The point of field evacuation criteria is to move patients who truly need higher-level care or rapid escalation. If a patient shows signs of deterioration or if there is life-threatening trouble that cannot be managed at the field unit—such as uncontrolled bleeding or a condition requiring surgical intervention—that clearly warrants evacuation. In contrast, a patient who remains hemodynamically stable and has had stable vitals for a full 24 hours is not something that automatically triggers transfer; stability suggests they can be cared for at the current facility and monitored locally. Of course, decisions can vary with resource limits or evolving needs, but as a typical criterion for evacuation, maintaining stable vitals for 24 hours is not a common trigger.
