Tactical Combat Casualty Care (TCCC) Practice Test

In Tactical Combat Casualty Care (TCCC), the choice of tourniquets for junctional hemorrhage control is critical, as not all tourniquets are designed for use at junctional sites, which are areas where arterial blood vessels are more difficult to compress due to anatomical structures.

The Standard Military Tourniquet (SMT) is primarily designed for extremity applications and may not be effective for junctional hemorrhages, such as those occurring at the groin or axilla. The SMT lacks the specialized design elements required to adequately control bleeding in these areas where anatomy presents a challenge.

In contrast, other options like the Combat Ready Clamp (CRoC), Junctional Emergency Treatment Tool (JETT), and SAM Junctional Tourniquet are explicitly engineered to address junctional bleeding. These devices employ unique mechanisms or configurations that allow for effective application and hemostatic control at junctional sites, making them appropriate choices in TCCC protocols.

Thus, while the other tourniquets listed are intended and validated for junctional use, the Standard Military Tourniquet is not recommended for this specific application, highlighting the importance of choosing the right equipment based on the type of injury being addressed.
