Unconsciousness after a severe head injury is an automatic 911 call "true"
Explanation:
In serious head injuries that abrupt stop can basically shut the brain down so fast that the patient falls unconscious. That is an automatic 911 call, even if they begin to recover afterwards. It's still a 911 call because that type of traumatic injury is bad enough that it could develop into a life threatening issue. A concussion occurs when the brain abruptly strikes the inside of the skull. In serious injuries, this rapid movement can basically shut the brain down so fast that the patient falls unconscious.
