A nurse stops at a motor vehicle collision to provide help for a victim who is trapped in an overturned running vehicle. The nurse turns off the engine key, and asks the client to wiggle the fingers because the client's head is impinged on the roof and the neck is bent to the left shoulder. After Emergency Medical Services (EMS) arrive, the nurse reports that the victim is conscious, but is not able to talk, and then the nurse leaves the scene. Which legal action can be taken in this situation?
