Thankyou all for the welcome.
Guy, Do you mean challenge as an RN/LVN? Or as a medic?
If you mean as a practicing nurse there is no challenge involved. All one has to do to get a license is pay the fee for "license by endorsement". They will require that the state you currently practice in as well as any others you hold licenses in, active or otherwise, send them the required information by mail.
You would have to contact every board you hold licenses in and have each respective board do this. There will be a small nominal fee for each board.
A license in CA will cost about approx $100.00. If you need to have one right away, ie you are on a travel assignment, you can go to Sacramento to the office directly and do all the paperwork in one day. There you can obtain a temporary permit and then recieve your actual license at a later date via snail mail. If you are going to do this via mail I recommend you get the temporary anyway as mistakes on their end can happen.
However, if you mean challenge as a medic I am not sure what direction to point you. I am aware of courses that other medical proffesionals from the ancillary depts take ie repiratory therapists most often, that are mostly course work followed by an intensive few days taking a pt assigmnet under direct observation. This somehow meets criteria for clinicals combined with whatever experience that the individual had in their prior discipline.
I do not personly know what schools do this but I do know individuals that have. I dont recommend it as even after two years of clinical experience concurrent with one year in a truamatic brain injury unit and medical telemetry unit I still was not fully prepared for life on the floor.
An internet search should provide you with some names and if you go this route I could make a call or two to see if people are familiar with them.

I hope this has helped at least a little-
