It is definitely illegal in all 50 states to misrepresent yourself as a nurse. If you do not have an LPN, ASSOCIATE degree in Nursing, BSN, etc, and are not currently licened in your state, you can be charged with practicing without a license, as well as other offenses. Next time someone calls themselves a nurse, its time to get a witness, and file it with the Board of Nursing. You can file a claim in confidence with all 50 Boards.More power to you!
