I am a new grad ADN nurse, who is also middle aged (44), and also worked as a CNA on the unit I currently work on (ED) for three years prior to becoming an RN. I think anyone who thinks getting a 2-year ADN is easy has never tried it. I do think that CNAs have no idea what a nurse actually does behind the scenes. That was one of the biggest transition areas I had to get used to. I was a rock star as an aide. When I first started orientation I went in with all the confidence in the world, maybe even thinking I could do the job with one hand By the end of the first week, I was like a deer in the headlights. I've found that most negative/derogatory comments stem from jealousy. Maybe encourage those aides to go to nursing school. It's never too late. I had a woman in my class who is 10 years older than me!
