"Mandated overtime" means work that is required by the hospital in excess of an agreed-to, predetermined work shift. Time spent by nurses required to be available as a condition of employment in specialized units, such as surgical nursing services, shall not be counted or considered in calculating the amount of time worked for the purpose of applying the prohibition against mandated overtime under subsection (b).
"Nurse" means any advanced practice registered nurse, registered professional nurse, or licensed practical nurse, as defined in the Nurse Practice Act, who receives an hourly wage and has direct responsibility to oversee or carry out nursing care. For the purposes of this Section, "advanced practice registered nurse" does not include a certified registered nurse anesthetist who is primarily engaged in performing the duties of a nurse anesthetist.
"Unforeseen emergent circumstance" means (i) any declared national, State, or municipal disaster or other catastrophic event, or any implementation of a hospital's disaster plan, that will substantially affect or increase the need for health care services or (ii) any circumstance in which patient care needs require specialized nursing skills through the completion of a procedure. An "unforeseen emergent circumstance" does not include situations in which the hospital fails to have enough nursing staff to meet the usual and reasonably predictable nursing needs of its patients.
