CNIM SSEP QUESTIONS AND ANSWERS 100%CORRECT | UPDATED 2024
If over three hours the PTN cortical response attenuates while subcortical is
stable:
A- Do a wake - up test
B- Stimulate peroneal nerve
C- Keep monitoring subcorticals
D- Inform the surgeon monitoring is no longer reliable - ANSWER C
In general, filter settings for SEP recordings
A- should always be 30 - 3000 Hz
B- can be narrower for cortical than peripheral responses
C- can be narrower for peripheral than cortical responses
D- should always include 60 Hz band pass filters - ANSWER B
Which of the following upper extremity somatosensory responses is considered a
"stationary potential"?
A- N18
B- P14
C- N13
D- N20 - ANSWER C
When monitoring with SSEPs, dural or direct cord recordings are advantageous
because:
A- the waveforms better reflect cortical responses to stimulation
,B- they present less discomfort to the patient than scalp leads
C- they have less chance of artifact during cauterization
D- the waveforms are higher in amplitude and require fewer averages -
ANSWER D
Electrical amplitude of the SEP is
A- 1000 uV to 10,000 uV
B- 10 to 100 uV
C- 0.1 to 10 uV
D- 100 uV to 1000 uV - ANSWER C
An advantage of referential, as opposed to bipolar recording of spinal cord
somatosensory evoked potentials, is
A- the ease of electrode placement
B- avoiding cancellation of the potentials as a result of recording from adjacent
levels
C- the elimination of electromyographic artifact from the paraspinous muscles
D- less invasion of the surgical field - ANSWER B
The SEP reaches adult form and latency by
A- 6 months
B- birth
C- 18 months
D- 8 years - ANSWER D
, The median nerve SSEP can be helpful as a measure of
A- cerebral blood flow
B- blood pressure variability
C- anesthetic dosage
D- lower spinal cord function - ANSWER A
The duration of a monophasic, rectangular pulse used for somatosensory
stimulation should be
A- 0.2 ms
B- 1 ms
C- 0.05 ms
D- 0.5 ms - ANSWER A
Preoperative baseline, sensory evoked potential values are essential to
intraoperative neurophysiological monitoring because
A- absolute boundaries for EPs obtained intraoperatively are not available
B- they help to establish the appropriate level of anesthesia
C- it is necessary to compare intraoperative values with laboratory normative data
D- latencies and amplitudes are highly variable - ANSWER A
What is the best montage to use to evaluate dorsal column activity?
A- CPc-EP
B- EPi-EPc
C- CS5-EPc
D- CPi-EPc - ANSWER C
