Need help with inservice for CMA's

Hi, I have been asked to present an inservice for the CMA's in the LTC facility that I work at. Although our facility is one of the top in the state it has really never concentrated any training for the CMA's. In the past year there has been a drastic increase in med. errors and in the last survey we received a 5% med error deficiency. I have been asked to cover the basics of the med. pass, they all know the basics because when I do a walk through with them they do it by the book. I want to possibly add some info on different meds. or new meds. I also want this to be interesting so they walk away with a real understanding. Any ideas, I would surely appreciate your help. I am not a Staff Developement nurse, I am a charge nurse who inherited this assignment.
