At 2:00 AM, a 17-year-old boy, accompanied by his 19-year-old girlfriend, had driven to the bar to give his father (who had been drinking large amounts of alcohol) a ride home. On the way back, they were involved in a motor vehicle collision. The boy has a large laceration with profuse bleeding on his forehead. His girlfriend is unconscious in the front passenger floor. The father is standing outside the vehicle, appearing heavily intoxicated, and is refusing care. What is the best way to gain consent to begin care for the driver, considering that he is a minor and his father has an altered mental status?
