The difference between an RN and an LVN is largely based, as mentioned above, on length of training and education. LVNs tend to have about two years of education at either professional schools or community colleges. RNs generally hold bachelor's or master's degrees and have more extensive education and practicum experience. The LVN makes less money and cannot perform certain tasks. For instance, most LVNs cannot start IVs, though some can draw blood if they have phlebotomy training, and they may not be able to give injections. In hospital settings, the LVN is there to support the work of the RN and works under supervision of at least one registered nurse. LVNs can do work like helping patients, washing or cleaning patients, changing bed linens, taking vitals and monitoring patients for an RN.
