What is the difference between an LPN Training and a RN? 

RN is registered nurse, it takes 3-4 years to get a degree. Basically RNs have more responsibility than LPNs, LPNs can't do the more advanced treatments that RNs can. and RNs get paid more than LPNs, LPN generally starts at about $18/hr and up and the RN is usually $23/hr and up.

LPNs and LVNs care for ill, disabled persons, convalescent, or injured in hospitals, nursing homes, group homes, private homes, dental offices, mental health institutions, community health clinics, and public health departments. The nurses collect samples for testing, perform routine laboratory tests, feed patients, and record food and fluid intake and output. Some LPNs help care for infants.
