Spinal instrumentation includes all of the following systems except
Cotrel‐Dubousset (CD instrumentation)
Schneider instrumentation
Texas Scottish Rite Hospital (TSRH instrumentation)
Luque L‐rod with sublaminar wires ✔Correct Answer-Schneider instrumentation
The agent least depressing SEP monitoring is probably
ketamine
sevoflurane
pancuronium
vecuronium ✔Correct Answer-ketamine
Hypercapnia:
pCO2 higher than normal
pO2 higher than normal
Hct higher than normal
Inhalational agent > 1 MAC ✔Correct Answer-pCO2 higher than normal
A patient is admitted to the operating room diagnosed with a herniated cervical disc at C 5/6
The most appropriate nerve(s) to monitor during the resulting surgical procedure would be the:
peroneal and ulnar nerves
median and posterior tibial nerves
median and auditory nerves
ulnar nerve ✔Correct Answer-median and posterior tibial nerves
General anesthesia during carotid endarterectomy includes all of the following advantages
except:
provides brain protection
prevents patient movement
provides rapid control of blood pressure
provides a measurement of brain activity ✔Correct Answer-Provides a measurement of brain
activity
When placing stimulating electrodes over a peripheral nerve to elicit a muscle response:
the positive electrode should be toward the peripheral portion of the nerve to be stimulated
the negative electrode should be toward the peripheral portion of the nerve to be stimulated
neuromuscular blockade must be in effect during stimulation
, The positive electrode must be directly over the nerve whereas the negative electrode needn't
be ✔Correct Answer-the negative electrode should be toward the peripheral portion of the
nerve to be stimulated
Trigeminal nerve stimulation will elicit a CMAP from which of the following:
Mentalis
Tongue
Trigeminalis
Temporalis ✔Correct Answer-Temporalis
The X cranial nerve can be monitored with electrodes inserted into the
lateral rectus muscle
vocalis muscle
trapezius muscle
tongue ✔Correct Answer-Vocalis muscle
In selecting the horizontal parameters of analysis, the
sampling rate should be at least two times greater than the highest frequency in the signal
sampling rate should be the equivalent of the highest frequency in the signal
analysis period should be at least twice the Nyquist frequency
analysis period should approach the Nyquist frequency ✔Correct Answer-sampling rate
should be at least two times greater than the highest frequency in the signal
Stimulation of the motor pathway at the spinal cord can be achieved with little movement in the
surgical field by
decreasing muscle relaxants
slowing the stimulation rate
increasing the stimulation rate enough to produce muscle tetany
increasing the stimulation duration ✔Correct Answer-increasing the stimulation rate enough
to produce muscle tetany
Which of the following will affect the neurogenic response to spinal cord stimulation the least?
shunting of current by irrigation fluid
muscle relaxants
insertion of hardware
anesthetic agents ✔Correct Answer-anesthetic agents
In monopolar facial nerve stimulation, positive charge flows
from cathode to ground
from cathode to anode
from anode to cathode
muscle to ground ✔Correct Answer-from anode to cathode
