what is a certified nurse assistant

Hello, I'm new. You all can call me Jasmine. I am a 26 year old certified nurse assistant! (That means I get to take care of people :3!! Yayy) I specialize in so I can also help others get their certification!! I'm obviously new here, however I somehow came across this place googling for after work.. weird! haha but I though this place seemed cool, so I figure I might as well join.
