What is one reason for administering TXA (Tranexamic Acid)?

Administering Tranexamic Acid (TXA) is primarily indicated for casualties at risk of significant bleeding, particularly when there is a likelihood that they will require a blood transfusion. TXA works as an antifibrinolytic agent, helping to stabilize blood clots and reduce excessive bleeding. This is crucial in traumatic situations where a rapid and effective response is needed to control hemorrhage and maintain hemostatic stability.

In a tactical combat environment, where resources and time are often limited, addressing potential hemorrhagic shock early can significantly improve a casualty's chances of survival. When a casualty is anticipated to need a blood transfusion, administering TXA can serve as an effective intervention to minimize blood loss before definitive surgical care can be obtained. The use of TXA has been supported by evidence showing that it can reduce mortality in trauma patients with major bleeding if given early.

Hence, the rationale behind option B directly aligns with the purpose of TXA administration in trauma care.
