Hey everyone. Could someone please tell me what the difference between a cna and a cma is? And which one is better. I just started cma classes and now im not so sure its better than being a cna...i want to be a nurse this is just a stepping stone. i thought cmas were better because they can give shots and draw blood...i dont think cnas could do that. please, someone, give me as much info that you can...im confused. thanks, ashley
