Upon discovering a child with a gunshot wound, what is the appropriate initial action after ensuring safety?

The correct initial action when discovering a child with a gunshot wound is to apply gauze sponges and apply pressure to control bleeding. This action is critical in trauma situations, particularly with gunshot wounds, where severe bleeding can occur. By using gauze to apply direct pressure to the wound, you can help to minimize blood loss and stabilize the child’s condition until emergency medical services arrive. It is crucial to act quickly because uncontrolled bleeding can lead to shock and, potentially, death.

While calling emergency services is important, immediate first aid measures like controlling bleeding take precedence in situations of life-threatening injuries. Waiting for a parent's arrival is not appropriate as they may not have the medical training necessary to assist, and it does not address the urgent need for medical attention. Attempting to clean the wound with water could introduce infection and does not address the immediate need to control bleeding. Thus, applying gauze and pressure is the most appropriate response.
