It's interesting, that while I could do certain things in the hospital as a nurse (simple stuff as well like cannulation) I can't do it 'out on the oad' - yet I can prescribe drugs that I couldn't do as nurse. It's fun having two roles jostling in my head - and it surprises some nurses when I know more about a bit of kit, or a disease than they do - because I'm 'only' an ambulance driver.
