Nurses have their scope of practice. If a nurse practices out of scope of practice, he or she may commit the "physician without license" crime. The "physician without license" crime includes the following two types: (1) the nurses practice the medical act, and (2) the nurses practice the assisting medical act without the physician's order. The nurses are in lack of the knowledge of legal aspects, so they do not well understand their scope of practice and what the "physician without license" crime is. The purpose of this paper is introduce two judicial decisions with regard to that nurses commit the "physician with license "crime. It is hope that the nurse can gain a better understanding of their scope of practice and not to commit the "physician without license" crime.
