Step-by-step explanation:
The correct answer is A. Apply firm pressure to the carotid artery to reduce the amount of bleeding. Applying firm pressure to the carotid artery is not recommended in the treatment of bleeding from a neck injury. The carotid artery is a major blood vessel in the neck, and applying pressure to it may increase the risk of further injury or complications. Instead, you should apply pressure to the bleeding site using a gloved fingertip or a sterile occlusive dressing. Gauze can be used to secure the dressing in place.
