ABRET EEG EXAM PART 2 Questions with
Verified Correct Answers
which of the following extra electrodes might best demonstrate the EEG activity
associated with focal motor twitching of the right corner of the mouth?
C5
sphenoidal electrodes are used to record activity from the
anterior temporal lobes
what additional electrodes could be placed to help decipher between artifact and
cortical activity
EOG electrodes
what type of monitoring would be useful in an EEG with a patient experiencing
syncope?
ECG
an abbreviated 10-20 placement, respiration, ECG and EOG monitors should be used
when recording
neonates
what additional monitoring should be done in a middle age patient who repeatedly
alerts from sleep during the EEG?
Respiration
brain abscess
focal polymorphic delta activity
,Cortical EEG recordings can be obscured in patients who are tense and anxious due to
myogenic artifact
which combination of settings will help enhance a low voltage slow wave that is being
masked by muscle activity?
Sen 5; LF .3; HF 35
to enhance the background alpha and beta asymmetry in an EEG record showing
moderately high voltage delta activity, the tech should use a
shorter time constant and increased sensitivity
A waveform of 0.5 Hz can be best enhanced with a filter of
LF 0.3 Hz
of the following, the BEST choice of reference to be used when recording in suspected
temporal lobe epilepsy is
CZ
Which montage would be best to localize occipital spikes by phase reversal?
circumferential bipolar montage
When using the average reference, if a spike-and-wave focus appears at C3, the
abnormality would be best enhanced by
excluding C3 and surrounding electrodes from reference
which of the following montages would best display the amplitude of a left temporal
spike
left temporal to the contralateral ear
, when attempting to minimize relentless muscle artifact on a recording, the tech should
be aware that lowering the high filter could cause the artifact to resemble
beta activity
Referential recording is most appropriate for measuring
voltage
which of the following settings could be used to reduce the effects of sweat artifact in a
patient with asymmetrical low-voltage fast activity?
-S = 5 microvolts/mm
-LF = 5 Hz
-HF = 70 Hz
which of the following is the most appropriate instrumentation setting change that
should be made in order to enhance cortical slowing?
Change the LFF from 1 Hz to .1 Hz
Fourteen and six Hz positive spikes are best recorded with
the contralateral ear reference
The best reference electrode in an awake patient with excessive temporal myogenic
activity would be
Cz
A slow wave focus is best seen with
LF 0.3 Hz, paper speed 15 mm/sec
Laplacian montage
