What is an important warning to give to a person when applying a tourniquet?

When applying a tourniquet, it is essential to communicate that while it may cause discomfort or pain, the application is a necessary and potentially life-saving action. The purpose of a tourniquet is to control severe bleeding, particularly in situations where traditional methods are insufficient. Informing the person that they might experience pain prepares them for what to expect and reassures them that this discomfort is a part of a critical intervention aimed at their safety. It emphasizes the importance of the measure being taken and helps the individual mentally prepare for the procedure, which can help reduce anxiety during a stressful situation.

The other options do not convey the critical need for understanding the pain associated with a tourniquet’s application and may not adequately prepare the person for the procedure.
