CNIM - SSEP NEWEST 2024 ACTUAL EXAM
COMPLETE 175 QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+

When recording a PTN SSEP, the Fpz-Cs5 channel records... - ANSWER✔✔ N34


Subcortical far-field potentials


In the 10-20 system of electrode placement, the point 20% (of the nasion-ion
distance) anterior to Cz is called... - ANSWER✔✔ Fz


An electrode measured 20% lateral to Cz on the right using 10-20 system is... -
ANSWER✔✔ C4


P14 is a far-field, subcortically generated response which probably reflects... -
ANSWER✔✔ Caudal medial lemniscal activity


Upper SSEPs


If over three hours the PTN cortical response attenuates while subcortical is
stable... - ANSWER✔✔ Keep monitoring subcorticals


In general, filter settings for SSEP recordings... - ANSWER✔✔ Can be narrower for
cortical than peripheral responses

,The initial waveform recorded of a near-field PTN cortical potential is... -
ANSWER✔✔ Positive due to electronic depolarization of the membrane under the
recording electrode.


A patient is admitted to the OR diagnosed with a herniated cervical disc at C5-6.
The most appropriate nerves to monitor during the resulting surgical procedure
would be the... - ANSWER✔✔ MN and PTN


SSEPs are most likely to be highly variable and less reliable in patients with... -
ANSWER✔✔ Neuromuscular disease


Lower extremity SSEPs are transmitted through the... - ANSWER✔✔ Gracilis
Nucleus


Stimulation of the motor pathway at the spinal cord can be achieved with little
movement in the surgical field by... - ANSWER✔✔ Increasing the stimulation rate
enough to produce muscle tetany.


Tetany - ANSWER✔✔ The involuntary contraction of muscles.


What upper extremity somatosensory response is considered a stationary
potential? - ANSWER✔✔ N13


Generated by the spinal cord


Near-field potential

, Blood supply handled by posterior spinal arteries.


The use of a 60 Hz notch filter is discouraged while recording because it can... -
ANSWER✔✔ Produce ringing artifact that can contaminate the appearance of the
response.


When monitoring SSEPs, dural or direct cord recordings are advantageous
because... - ANSWER✔✔ The waveforms are higher in amplitude and require
fewer averages.


Electrical amplitude of the SSEP is... - ANSWER✔✔ 0.1 to 10 uV


The advantage of referential, as opposed to bipolar recording of spinal cord
SSEPs, is... - ANSWER✔✔ Avoiding cancellation of the potentials as a result of
recording from adjacent levels.


What is the main advantage of asynchronous bilateral stimulation? - ANSWER✔✔
Differentiation of local vs. systemic effects


What is the best monitoring strategy for a C7 fracture? - ANSWER✔✔ UN and PTN
SSEPs


MN SSEP produces a wave at the brachial plexus designated... - ANSWER✔✔ N9


The SSEP reaches adult form and latency by... - ANSWER✔✔ 8 years
