When I was in Nursing School, we did practice on the dummy arm first, then a classmate. However, there is a limit to what you can do or not do to another human being.
Would you have all med students and nursing students go out and shoot pigs just so they could get some experience?
I took ACLS classes and learned enough using a dummy that I was able to intubate and start jugular IVs on real people.
