No nursing home in the state may operate unless it is under the supervision of an administrator who holds a currently valid nursing home administrator’s license, or provisional license, issued by the Board of Examiners of Nursing Home Administrators. No person shall practice or offer to practice nursing home administration in this state or use any title, sign, card, or device to indicate that he or she is a nursing home administrator unless such person shall have been duly licensed as a nursing home administrator or as a provisional nursing home administrator. In the event a nursing home administrator dies, unexpectedly resigns, becomes incapacitated, or has his or her license revoked, the person or persons then responsible for the management of the nursing home shall immediately notify the Board of Examiners of Nursing Home Administrators and the agency issuing the nursing home license and shall be allowed a reasonable period of time, in accordance with policies adopted by the board, to be established by the agency issuing the nursing home license, not to exceed 180 days from the date of the death, unexpected resignation, incapacitation, or revocation of the license of the nursing home administrator in which to replace the administrator. During the reasonable period of time, the board may issue an emergency permit to a person performing the functions of administrator in such nursing home without being in violation of the provisions of this chapter.
