Intraoperative Neurophysiologic Monitoring: Basics and Beyond

View Course Details Please note: exam questions are subject to change.

1.  Typical OR attire includes:
  1. your favorite open-toed shoes
  2. excessive jewelry
  3. OR-provided scrub top & pants
  4. any hairstyle that would not fit under an OR hat
2.  During the safety time out, which of the following items of information is reviewed by the entire OR team prior to incision?
  1. patient name and date of birth
  2. exhaustive review of patient history
  3. contact number for relative who will receive updates throughout the case
  4. baseline intraoperative neurophysiologic monitoring (IONM) data
3.  ____________ is an example of a stimulus feature:
  1. analysis time window
  2. artifact rejection
  3. intensity
  4. amplification
4.  ___________ is an example of a patient factor to consider for IONM:
  1. previous diagnoses/surgeries
  2. basic neurological exam/neurological symptoms
  3. both a & b
  4. social history
5.  Which of the following is a commonly utilized IONM modality:
  1. Electromyography (EMG)
  2. Visual-Evoked Potentials (VEPs)
  3. Vestibular-Evoked Myogenic Potentials (VEMPs)
  4. Auditory Brainstem Response (ABR)
6.  What method of monitoring allows for detection of the electric potential generated by muscle cells when the cells are activated?
  1. Electromyography
  2. Auditory Evoked Potentials
  3. Direct Nerve Stimulation
  4. Somatosensory Evoked Potentials
7.  What is the most appropriate method of monitoring for a sensory nerve?
  1. Evoked Potentials
  2. Electromyography
  3. Direct Nerve Stimulation
  4. Transcranial Evoked Potentials
8.  Which of the following cranial Nerves are monitored by electromyography?
  1. Cranial Nerves V, VII, VIII, IX
  2. Cranial Nerves V, VII, IX, X
  3. Cranial Nerves II, V, VII, IX, X
  4. Cranial Nerves II, V, VII, VIII, IX
9.  Which of the following is not a significant source of electrical noise in the operating room?
  1. Electrocautery Devices
  2. Unplugged Surgical Equipment
  3. Fluid Warmers
  4. Parallel Cord Arrangements
10.  In terms of anesthetic, volatile gasses:
  1. tend to wipe out the ABR
  2. tend to create a more robust Vestibular Evoked Myogenic Potential (VEMP)
  3. can wipe out any Vestibular Evoked Myogenic Potential (VEMP) but ABR is generally not impacted
  4. are no longer used in surgeries
11.  What mode of monitoring is a "diagnostic procedure to assess the health of muscles and the nerve cells that control them".
  1. Transcranial Motor Evoked Potentials
  2. Electromyography
  3. Pedicle Screw Stimulation
  4. Somatosensory Evoked Potentials
12.  Transcranial Motor Evoked Potentials are:
  1. one of the oldest forms of stimulation for monitoring of the motor pathways
  2. an excellent method of monitoring motor function if seizure history precludes EMG
  3. stimulation of the sensory cortex and recording over the limbs
  4. electrical signals recorded from neural tissue or muscle following activation of central motor pathways
13.  In a thoracic procedure, which of the following is an uncommon mode of monitoring?
  1. Upper Limb SSEP
  2. Lower Limb SSEP
  3. EMG
  4. TcMEP
14.  In a lumbar procedure, which of the following modes is rarely performed?
  1. SSEP
  2. EMG
  3. TcMEP
  4. Direct Nerve Stimulation
15.  What types of equipment rarely introduce electrical noise artifact in the operating room?
  1. Fluid warmers
  2. Unplugged surgical beds
  3. Grounded extension cords
  4. Computers on wheels
