Intraoperative Neurophysiologic Monitoring: An Introduction to the Operating Room for the Audiologist

---

1.  As an audiologist working in the operating room (OR), you will be part of a patient-care team that includes which of the following roles: anesthesia staff &/or anesthesiologist circulating nurse scrub nurse/technician all of the above

2.  Typical OR attire includes: your favorite open-toed shoes excessive jewelry OR-provided scrub top & pants any hairstyle that would not fit under an OR hat

3.  During the safety time out, which of the following items of information is reviewed by the entire OR team prior to incision? patient name and date of birth exhaustive review of patient history contact number for relative who will receive updates throughout the case baseline intraoperative neurophysiologic monitoring (IONM) data

4.  The ABCs of anesthesiology include: Airway Management, Blood Pressure, & Cardiac Output Airway Management, Breathing/Ventilation, & Circulation Analgesia, BreathingNentilation, & Circulation None of the above

5.  ____________ is an example of a stimulus feature: analysis time window artifact rejection intensity amplification

6.  ___________ is an example of a patient factor to consider for IONM: previous diagnoses/surgeries basic neurological exam/neurological symptoms both a & b social history

7.  How are neurophysiologic potentials that are miniscule in amplitude collected from the patient despite the presence of larger-amplitude, non-potential related activity (whether biologic or electrical in origin)? differential amplification common mode rejection signal averaging all of the above

8.  Which of the following is a commonly utilized IONM modality: Electromyography (EMG) Visual-Evoked Potentials (VEPs) Vestibular-Evoked Myogenic Potentials (VEMPs) Auditory Brainstem Response (ABR)

9.  To reduce artifact levels in neurophysiologic response(s) collected in the OR, which of the following strategies could be implemented: increase signal averaging improve neurophysiologic response(s) identify any source(s) of electrical artifact and move away from the source(s) all of the above

10.  What is a common source of artifact encountered in the OR that prohibits interpretation of neurophysiologic data? myogenic activity due to restless patient state cautery (bovie, bipolar) faulty equipment none of the above
