I recently got a job as a CNA at a hospital here in the Twin Cities. The position is for an NST/HUC (pretty much the same thing as a CNA, lots of responsibilities everywhere) and I can agree with most of what everyone is saying. For me, I wasn't even getting interviews without having NA experience elsewhere, just to get a job as an NA in a hospital. I have a few nurses I work with that started out as an NA/HUC at the desk, and then were offered RN jobs when they were almost finished with RN school.
It's really all about what you want! If your program requires CNA, definitely do it, but if you just want experience, maybe you should try it
I can honestly say it's not my favorite... it's a lot of work and many patients per NA (of course, you work under an RN!) but still, it's difficult. I tried working in Senior Care and I just couldn't do it. I lasted about 3 weeks.
I hope everything works out for you!
