I have been an RN for almost three years now. I was a certified medical assistant before becoming a nurse. To keep your certification as a CMA you have to do X amount of CEUs every 5 years and pay $120. I kept my certification up in nursing school for employment; but now that I am a nurse I am wondering what's the point? Have any RNs that either were Certified Medical Assistants or LVN/LPN kept their lower level experience certification and/or licenses up? If so, what was your rational?
