During casualty evaluation, which of the following is prioritized for treatment?

In the context of Tactical Combat Casualty Care (TCCC), controlling major hemorrhage is prioritized for treatment because it directly addresses a leading cause of preventable death on the battlefield. Severe blood loss can rapidly lead to shock and death if not managed immediately. The primary goal in any trauma scenario is to stabilize the patient, which begins with controlling any life-threatening conditions, particularly hemorrhage.

By prioritizing the management of major bleeding, medical personnel can ensure that the casualty has the best chance of survival before addressing less critical issues such as minor injuries, administering comfort medications, or documenting patient history. These latter aspects are important but secondary to the immediate need to stop bleeding and ensure the casualty's vital signs are stable. Thus, focusing on hemorrhage control is essential for effective trauma care in combat situations.
