Final answer:
To cover complications of open neck injuries, the location of the wound determines the method. In the oral cavity, cover the wound externally; in the larynx, cover the wound internally.
Step-by-step explanation:
When covering complications of open neck injuries, the placement of the wound will determine the appropriate method. If the injury is in the oral cavity, it is important to cover it externally to protect it from infection and further damage. Conversely, if the injury is in the larynx, covering it internally is necessary to protect the airway.
