Final answer:
Keeping the tourniquet on for 3 minutes can lead to a prolonged vascular spasm response and potentially affect the process of hemostasis.
Step-by-step explanation:
Keeping the tourniquet on for 3 minutes can lead to a prolonged vascular spasm response and potentially affect the process of hemostasis. The vascular spasm response is triggered by chemicals called endothelins that are released by vessel-lining cells and pain receptors in response to vessel injury. This response helps to constrict the blood vessels and reduce blood flow to the injured area, aiding in the formation of a blood clot.
