What are the three primary objectives of TCCC?

The three primary objectives of Tactical Combat Casualty Care (TCCC) focus on addressing the critical needs of a casualty in a combat setting. The correct response encapsulates these objectives effectively: treating the casualty, preventing additional casualties, and ensuring the mission is completed.

Treating the casualty is paramount as delivering medical care promptly can significantly increase the chances of survival. This involves managing life-threatening injuries and stabilizing the patient for further evacuation or advanced care.

Preventing additional casualties is crucial in a combat environment. This involves not only addressing the immediate threats that may cause harm to the casualty or bystanders but also ensuring that actions taken do not inadvertently escalate the situation or put others at risk.

Completing the mission integrates the tactical aspect, where the care given must also align with operational goals. Medics must balance lifesaving interventions with the necessity to continue the mission, as prolonged engagements can result in further casualties.

Other options listed focus on aspects of care but do not fully capture the comprehensive objectives of TCCC. For instance, assessing injuries and calling for backup or securing the area has value but do not prioritize the immediate medical needs and operational mission completion as outlined in the correct choice.
