LVN vs. LPN: What Is The Difference Between LVN and LPN? Here is what is meant by LVN vs. LPN: licensed practical nurse (LPN) can also be called a licensed vocational nurse (LVN). As such, there is no essential difference other than in grammatical terms. It is possible for someone to enter the health industry as a LVN or a LPN. In certain states of America you would be known by either of the names, however, the role that you perform will be the same.
The National Council Licensure Examination-Practical Nurse (NCLEX-PN), a computer-based national licensing exam developed and administered by the National Council of State Boards of Nursing, is the exam required to obtain licensure as a LPN/LVN. In many states, LPNs/LVNs are required to obtain continuing education credits throughout their career.
