True or False: An effective tourniquet application can cause pain.

An effective tourniquet application can indeed cause pain. When a tourniquet is applied, it compresses the blood vessels to stop bleeding, which can lead to significant discomfort or pain in the area where it is applied. This pain is a natural response to the pressure being exerted on the tissues and nerves.

It's important to recognize that while the primary goal of using a tourniquet is to control life-threatening hemorrhage, the procedure may be distressing for the patient. Ensuring that the tourniquet is applied appropriately is crucial to both achieving effective blood flow control and managing pain when possible. Thus, the understanding that pain can accompany tourniquet use is integral to the TCCC principles, as it highlights the need for careful assessment and compassionate care during trauma interventions.
