Now I am confused. The LPN program you attended is only accredited in California? Did you comp the LPN exam in California, or did you go to LPN school? If you were a CNA who comped the NCLEX-PN, then it is only recognized in California, as I understand it. Mass is different in that you can't even sit for the NCLEX-PN if the school is not accredited, and there is no comping. I have not heard of others who had difficulty in obtaining licesnes in other states from the school I attended, but it was accredited.
If it is a matter of taking an entire LPN course of study again, I would think about-- for probably just a little more time-- look into some local colleges and see what is out there for RN. Each college that offers an RN program that allows you to sit for the NCLEX-RN has clinicals as part of that course of study. Contact some local schools and see. You could obtain your associates RN and then think about continuing to your BSN online, but I would actually go to a college for your RN if you are able. If your LPN licesne is only good in CA, then that could be an issue with online stuff, but I don't know. Online is based on an LPN to RN course of study, but I believe one has to have gone to an accredited LPN school.
If you contact the school you obtained your LPN from, ask them if they are accredited, and if California is the only state that recognizes them. I am sure that you are not the only one who has attempted to get a job in a different state and had this issue. Ask them how others have done this. Then, if they are accredited nationally, I would contact the BON again in Nevada with this information.
Meanwhile, how close are you to CA? Is it worth it to commute to CA for a job, even if it is part time while you go to school?
