In addition to the duties and responsibilities provided in chapters 147 and 272C, the board shall adopt rules for granting a provisional license to an administrator appointed on a temporary basis by a nursing home’s owner or owners in the event the regular administrator of the nursing home is unable to perform the administrator’s duties or the nursing home is without a licensed administrator because of death or other cause. Such provisional license shall allow the provisional licensee to perform the duties of a nursing home administrator. An individual shall not hold a provisional license for more than twelve total combined months, and the board may revoke or otherwise discipline a provisional licensee for cause after due notice and a hearing on a charge or complaint filed with the board.
