I'm not sure about your state, but in mine a nurse cannot work in a job for which he or she does not hold the appropriate license. I am an RN, but I cannot take an LPN position because I don't have a PN license.
I would contact the State personnel board and ask about this. When I inquired, there were positions listed for both the RN and LVN level, so I would assume one would have no problem qualifying at the RN level and receiving the RN level of pay. Call them and ask.
