Which of the following should you avoid doing if someone is bleeding heavily?

If someone is bleeding heavily, moving them suddenly can exacerbate the situation by causing shock or increasing blood loss. Sudden movement may dislodge any clots forming over the wound and can lead to further injury, particularly if the person has sustained trauma that is not immediately obvious. It is crucial to maintain their current position as much as possible to prevent aggravating their condition.

In contrast, applying direct pressure is a crucial first-aid step to control bleeding, keeping the person calm is essential to prevent shock, and raising the affected area, if practical, can help reduce blood flow to the injury. Therefore, avoiding sudden movement is important to stabilize the injured person and ensure they receive appropriate care.
