I wondered the same thing. Though I didn't find anyone willing to share that info (several nurses in my family), salary.com gave me a general idea of what to expect. I can't guarantee it's accuracy but it was what I expected to see.
I just graduated LPN/LVN school and I live in texas right out of school I'll be started out at 11.80$ plus where I work I will get shift dif. for working nights...but as for RN right out of school they make between 16-17$ an hour.
I went to the nursing homes where they were short staffed, I then told them I wouldn't work for less than 20/hr. They hired me then I moved around to other places using the 20/hr as my lowest bid.. Agency is great, they pay 30/hr, It's alot more interesting to.
