What should you do first when performing first aid for a severe cut?

When managing a severe cut, the most critical initial action is to apply a pressure bandage. This step is essential because it helps control bleeding by applying direct pressure to the wound, which can significantly reduce blood loss and stabilize the injury. Controlling bleeding is a priority in first aid since uncontrolled bleeding can lead to shock or other serious complications.

Following the application of a pressure bandage, seeking medical attention is typically the next step, especially for severe wounds. Cleaning the wound and applying ice can be appropriate actions afterward but are secondary to addressing immediate life-threatening concerns such as heavy bleeding.
