Answer: Summon more advanced medical personnel and place the victim into a position that helps breahing.
Explanation: In the event of someone falling and banging their head it is imperative that you check them and make sure they show signs of life, e.g. breathing, they need to breathe to sustain life
The other thing is never move a patient from the scene unless there is immediate danger, its best to summon medical assistance, but first you must check their ABC,
A - Airway, is it blocked, put your fingers in their mouth and check for any foreign objects which may cause choking,
B - Breathing, are they breathing, there isn't much point moving someone or doing anything else unless they are breathing.
C - Chest compressions, start chest compressions to restart their breathing - make sure you read up on this and know how to place your hands over the victims chest though I think just recently that has been scrapped and its just a case now of pumping an adults chest with your hands best way possible to get their breathing going again. (this step should be done by trained personnel as this can cause rib breakage)
