1. There shall be a professional licensure division within the department of public health. Each board under chapter 147 or under the administrative authority of the department, except the board of nursing, board of medicine, dental board, and board of pharmacy, shall receive administrative and clerical support from the division and may not employ its own support staff for administrative and clerical duties. The executive director of the board of nursing, board of medicine, dental board, and board of pharmacy shall be appointed pursuant to section 135.11B.
 2. The professional licensure division and the licensing boards may expend funds in addition to amounts budgeted, if those additional expenditures are directly the result of actual examination and exceed funds budgeted for examinations. Before the division or a licensing board expends or encumbers an amount in excess of the funds budgeted for examinations, the director of the department of management shall approve the expenditure or encumbrance. Before approval is given, the department of management shall determine that the examination expenses exceed the funds budgeted by the general assembly to the division or board and the division or board does not have other funds from which examination expenses can be paid. Upon approval of the department of management, the division or licensing board may expend and encumber funds for excess examination expenses. The amounts necessary to fund the excess examination expenses shall be collected as fees from additional examination applicants and shall be treated as repayment receipts as defined in section 8.2.
