What does a Med Passer do?

Here is what I got from Careerbuilder.com, I cannot copy and paste so it is a summary, a med passer is a C.N.A who gives care to nursing home residents. So you basically take care of old people and you have to be a certified CNA which is a Certified Nursing Assistant. You do have to have a certain amount of training hours to become certified. So you may want to look for some classes.
