It is of importance to distinguish between degree title and professional title. In Sweden, the following applies: A professional title grows out of a developed custom in accordance with demands of a certain level of academic education. Therefore, many titles are not protected by law.
However, the professional title "nurse" is an example of a protected title, which may only be used by a registered nurse. Furthermore, only a registered nurse may be employed as a nurse within a municipality's or a county council's health care. The authorization is issued by Socialstyrelsen (the National Swedish Board of Health and Welfare), which offers more information about this on their homepage.
