The practice of professional nursing or practical nursing by any person who has not been issued a license under the provisions of this Article (unless covered by an exception herein given), or whose license has been suspended or revoked or has expired is hereby declared to be contrary to the law, public policy, and to be a danger to the health and welfare of the public. In such a case, the Board can request the Attorney General to enjoin the individual from practicing professional nursing or practical nursing, as the case may be. Upon the filing of a complaint for injunction against a person violating the provisions of this Article, the court or any judge thereof may issue a temporary injunction against the person or persons charged in the action without notice or bond, enjoining such person or persons from further practicing professional nursing or practical nursing, as the case may be, until a final hearing of the matter or under a valid license is secured.
