What is the term used when bleeding stops after applying a tourniquet?

hematemesis
hemiplegia
hemolysis
hemostasis

The correct answer is: hemostasis

Hemostasis refers to the process of stopping bleeding, which can occur through various mechanisms in the body, including the application of a tourniquet. When a tourniquet is applied effectively, it compresses the blood vessels, restricting blood flow to the injured area and thus halting the bleeding. This is a crucial skill for EMTs, as properly applied tourniquets can prevent significant blood loss and stabilize a patient until further medical help is available. In contrast, the other terms relate to different processes or conditions: hematemesis refers to vomiting blood, hemiplegia indicates paralysis on one side of the body, and hemolysis involves the destruction of red blood cells, which is unrelated to the cessation of bleeding. Understanding hemostasis and its application in emergency situations is vital for anyone involved in emergency medical services.
