Hello, I am currently going to school and plan to become a nurse. I am researching the different certifications that are available to RNs. When an RN says they are certified in a given specialty, what exactly do they mean? do they mean board certified? If so, is there one set of board certifications that are available/recognized, or are there an infinite number of "certifications". What I am looking for is a comprehensive list of all possible certifications, but I guess I truly need to understand, specifically, what one means when they say "certified". If you can point me to a comprehensive list, that would be great. Thanks in advance! -Heather Janes
