As an LPN, I would check out any local LTC facilities in your area and give them a call. Not all hospitals hire LPNs, so that would require more research. I believe Montefiore and the HHC hospitals do hire LPNs. If your looking for part-time or per diem work, know that they will expect you to have a few years under your belt.
Hospitals might ask you for letters of recommendations, but usually they just call your previous jobs to verify employment (in my experience).
Hope this helps,
