Why does the nurse have to be at the head of the patient when the patient is being escorted in a wheelchair or trolley? What information is available to support this?

Why is it necessary to be in front? Not necessarily. This thing is flexible. Because of the wheelchair, the nurse must be behind the patient. With a flat car, if there is a family member to push the car, the nurse in the front of the flat car can grasp the direction of the car, but also can be a little lazy to save energy. If there is no family, the nurse cart, can only be in the rear of the flat car.
