Which statement is true regarding pressure application on a wound?

Applying firm pressure on a wound is crucial for controlling bleeding. When a person suffers a wound, especially one that is deep or bleeding heavily, firm pressure helps to compress the blood vessels at the site of the injury, which can significantly reduce or stop blood flow. This action is vital to prevent excessive blood loss, which can lead to shock or other serious complications.

Light pressure may not adequately control bleeding in the case of more severe injuries, and quickly removing the pressure to check on the bleeding could disrupt any clotting that has begun. Additionally, applying pressure only to the edges of the wound is not effective, as it does not address the area actively bleeding where the blood vessels are compromised. Thus, firm and direct pressure over the wound is the most effective method for managing bleeding.
