Final answer:
In triage, a head injury with severe bleeding would be considered the highest priority (red).
Step-by-step explanation:
In triage, the injury that would be considered to have the highest priority ('red') is a head injury with severe bleeding. This is because head injuries can be life-threatening and may result in immediate death or disability. Severe bleeding from the head can indicate damage to major blood vessels, which requires immediate medical attention to control the bleeding and prevent further complications.
