In the case of a pedestrian with a severe bleeding wound on their leg, what is the appropriate initial response?

Applying firm pressure to the wound is essential in managing severe bleeding. This technique helps to stem the flow of blood and promotes clotting, which is crucial in preventing further blood loss. Immediate pressure on the wound can significantly reduce the risk of shock and other complications associated with severe bleeding.

While other responses may seem reasonable, they either do not prioritize the immediate need to control bleeding or could potentially exacerbate the situation. For instance, raising the leg may not be appropriate if the bleeding is severe, as it can hinder blood flow back to the heart and potentially increase the bleeding in certain scenarios. Cleaning the wound with antiseptic should only be considered after bleeding has been controlled, as it does not address the most pressing issue at hand. Keeping the person still and calm is important for overall care; however, it does not provide any direct intervention for the bleeding. Thus, the focus should be on applying pressure to effectively manage the immediate threat of blood loss.
