Difference between LPN and LVN ??

Hello,

I am starting school to become an LPN this fall. I just moved to Florida from California. I am finding alot of jobs in the classifieds for LPN's here, of course not for hopstials, but the jobs are out there.

Now, when I do a search in California, in case i were to ever go back, I dont see any LPN jobs. I see tons of LVN's. Are they the same thing? If I go back to CA and would I be able to get an LVN lisence or would I have to go back to school to be an LVN?

Thanks for any help you can give me!
