I started in the RN program at 30 (career change). I dropped out due to a divorce, then started on my LPN b/c it was quicker. I plan on getting my RN in the next few years. LPN's ARE limited, but I've found alot of places don't use them to their full potential. For instance, a few places around here won't let LPN's start IV's, even if you're certified. Pay and sign on bonuses are a lot higher for RN's too. Good luck
From talking to other nurses tho, it seems that they would rather work with RN's that have experience as an LPN than just right out of school with no kind of healthcare experience. I've met LPN's that have 30 years under their belt and they really know their stuff, but yet I have brand new RN's that don't know how to do a tubefeed. All of it takes time, tho. Just my experience/opinion.
