Audible Facial Nerve Monitors (Nerve Integrity Monitor Systems)are Used Intraoperatively

Audible facial nerve monitors (nerve integrity monitor systems) are used intraoperatively during procedures in which the facial nerve is at risk for injury.The purpose of this monitoring technique is to assist in the early identification of the nerve,to increase the possibility of its preservation by minimizing trauma,and to assess its integrity after dissection.Communication with the anesthesia provider is essential because:

A) the electrodes are often in proximity to the anesthetic airway.
B) manipulation of the anesthetic airway during the procedure can misplace the electrodes.
C) muscle relaxants, paralyzing agents, and some local anesthetics must be avoided.
D) the anesthesia provider is responsible for the facial nerve monitoring.
