Who is authorized to remove a tourniquet?

The correct choice highlights that only medical personnel are authorized to remove a tourniquet. This is critical because tourniquets are used in emergency situations to control severe bleeding. Once applied, a tourniquet can significantly restrict blood flow and should remain in place until a trained professional can assess the situation. Medical personnel have the requisite training to determine if and when it’s safe to remove the tourniquet, considering the patient's condition and the risks involved.

Other individuals, including first responders and bystanders, may not have the necessary training to assess the potential consequences of removing a tourniquet, which could lead to further complications or catastrophic bleeding. Therefore, this protocol is in place to ensure the highest level of care and safety for the injured individual.
