Rescue Task Force (RTF) Practice Exam

The correct answer is that combat gauze must make contact with the bleeding artery because its primary function is to effectively control severe bleeding, especially from traumatic injuries. Combat gauze is designed to be applied directly to the source of bleeding, which is often the artery when there is a significant or life-threatening hemorrhage.

When placed over a bleeding artery, the hemostatic agents within the combat gauze promote clotting and help to stabilize the wound. This action aids in reducing blood loss and facilitates effective care before the patient can receive further medical treatment.

In contrast, while an open wound is relevant to the application of combat gauze, the focus is specifically on controlling bleeding. Similarly, addressing a bone fracture or a contused area does not directly pertain to the immediate need for applying gauze to an area actively bleeding, since fractures may not always involve direct blood loss, and contusions also typically do not require gauze application in the same manner as an arterial bleed. Therefore, making contact with the bleeding artery is crucial for the gauze to serve its intended purpose of hemostasis.
