Hi my wonderful and inspiring nurses. I always have heard about what LPN can and cannot do and only heard of the real difference is the fact that LPNs get paid less than an RN . however , my professor told me that LPN and RNs work together and LPNs would supervise patients and CNAs/PSWs and would almost do the same thing like what an RN would do . so exactly why do the majority so badly want to be an RN instead of staying as a LPN?
