1. In intraoperative neuromonitoring, which technique is used to
assess the integrity of the brainstem during surgery?
A. Electroencephalography (EEG)
B. Brainstem auditory evoked potentials (BAEP)
C. Somatosensory evoked potentials (SSEP)
D. Motor evoked potentials (MEP)
Answer: B) Brainstem auditory evoked potentials (BAEP)
Rationale: BAEPs assess brainstem function, particularly the
auditory pathways, which are crucial during surgeries near the
brainstem, such as tumor resections.
2. During brain surgery, which technique is commonly used to
monitor the function of the brain cortex?
A. Brainstem auditory evoked potentials (BAEP)
B. Electrocorticography (ECoG)
C. Somatosensory evoked potentials (SSEP)
D. Visual evoked potentials (VEP)
Answer: B) Electrocorticography (ECoG)
Rationale: ECoG is used to monitor cortical activity directly by
placing electrodes on the surface of the brain.
,3. Which of the following is the most common indication for
intraoperative neuromonitoring during spine surgery?
A. Assessing sensory function
B. Identifying tumor metastasis
C. Detecting nerve root damage
D. Monitoring brain activity
Answer: C) Detecting nerve root damage
Rationale: Intraoperative neuromonitoring during spine surgery is
mainly used to detect nerve root damage, especially when
manipulating or decompressing spinal structures.
4. The most critical action if there is a significant drop in
amplitude during intraoperative monitoring of somatosensory
evoked potentials (SSEP) is:
A. Adjust the anesthetic level
B. Discontinue the surgery immediately
C. Notify the surgical team and check for potential neural
compromise
D. Increase muscle relaxation
Answer: C) Notify the surgical team and check for potential neural
compromise
Rationale: A drop in amplitude suggests potential injury or
ischemia, requiring immediate assessment to protect neural
structures.
, 5. Which of the following is commonly used to monitor brainstem
integrity during surgery?
A. Electroencephalography (EEG)
B. Somatosensory evoked potentials (SSEP)
C. Brainstem auditory evoked potentials (BAEP)
D. Motor evoked potentials (MEP)
Answer: C) Brainstem auditory evoked potentials (BAEP)
Rationale: BAEPs are used to monitor the integrity of the
auditory pathways, particularly the brainstem, during surgeries
that may affect brainstem function.
6. The use of electromyography (EMG) during surgery allows for
monitoring of which of the following?
A. Sensory pathways
B. Motor pathways and muscle function
C. Brain electrical activity
D. Auditory pathways
Answer: B) Motor pathways and muscle function
Rationale: EMG is used to monitor motor function and muscle
activity, providing information on the integrity of motor pathways
during surgery.
