OK Kendall – here is a scenario for you. A mother who happens to be a nurse decides its time to go and do the weekly shopping. She straps her young child into the child safety seat in the back of the car and proceeds into the town. Very little traffic on the road apart from the car in front of her. Suddenly, from out of 'nowhere' a child runs onto the road in the path of the car in front of her, and gets knocked down.

So we have a child lying injured and possibly unconscious in the road, the driver of the vehicle still sitting behind the wheel of his car, presumably in deep shock.

The mother with the child in the car is, don't forget, a trained nurse. Her speedy actions could mean life or death for the injured child in the road.

What does she do?
