Hello everyone! My name is Sonya and I am working as a Medical Assistant and am currently going to school to get my certification in Mecial Assisting. I was unable to go to nursing school because of personal and health issues, but found an online medical assisting program to further my education. My biggest question is "what is the difference responsibility wise between an LPN, an LVN, and a CMA?" if anyone could help me with this question, I would be greatly appreciative.
