RN Sup pay rate?

hi all.  

Yes, I've done some research, but as usual prefer to get input from actual people.  I'm very new to long term care but have 16 years RN experience (varied: mostly cardiac, some ICU, trauma step-down, hemodialysis, psych/addiction for some background)

Thus, I said something like start me at whatever is comparable for a new to this position but experienced RN would start at.  I think it's a bit low, but whatever.  

A few months go by, I planned to ask for a bit of a raise, after a few months.  that time is now & I know they love me (Administrators & owners!)  They also have terminated the assistant DON position and I am planning on getting the infection preventionist certification, actually right now.  I had planned on ensuring an ample raise occurred.  

I know Agency LPN's here make more: they can be $45/hr, I'm $40.  Is that somewhat comparable to other dayshift RN supervisors in PA?  (A somewhat rural area, which I'm sure most already figured!)

thanks for any opinions & advice!
