In Utah (the Wasatch Front) the starting wage for an RN is $21.80 for all area's of a hospital. They do pay shift and weekend differential. The hospitals do not pay more for a BSN.
I did receive a job offer in Las Vegas, ER, I have 11 years experience, starting me out at $41.00; after shift and weekend differential it went up to just slightly under $45.00. I am unsure if there is a pay difference for BSN.
