QUESTIONS WITH UPDATED
ANSWERS
You are called to do an EEG on a patient who was found down for an unknown amount
of time. Based on your findings, you decided to perform cerebral death protocol via your
labs policy. The sensitivity should be increased to - CORRECT ANSWER>>>>2 uv/mm
A recording directly from the brain - CORRECT ANSWER>>>>Electrocorticorgraphy
Tacys Sachs disease is associated with - CORRECT ANSWER>>>>Cherry red spots in
the eyes
You are recording in a longitudinal (double banana) montage. You see a spike
discharge phase reverse at C4 and T4. In this case the true localization of the spike can
best be see in a - CORRECT ANSWER>>>>transverse montage
If the time (horizontal) scale is changed from 30mm/sec to 15mm/sec, the 6 hertz
activity becomes - CORRECT ANSWER>>>>there is no frequency change but the
activity appears faster
Which of the follow drugs show the most observable effects on the EEG? - CORRECT
ANSWER>>>>Benzodiaepines
The notch filter can distort spikes and should only be used when other measures to
reduce ____ interference fail - CORRECT ANSWER>>>>60Hz
Lambda waves can be associated with - CORRECT ANSWER>>>>saccadic eye
movement
Wernickes Encephalopathy can be cause by - CORRECT ANSWER>>>>Thiamine
deficiency
During a bipolar recording, you notice sharp activity from F7-T3 that shows an upward
deflection, T3-T5 shows no activity, and T5-O1 shows a downward deflection. Which
statement below best represents the above scenario? - CORRECT
ANSWER>>>>Equipotential at T3 and T5
A characteristic of this disease is high amplitude spikes in the occipital region, time
locked with a slow photic stimulus rate in young children - CORRECT
ANSWER>>>>Batten's disease
Which are of the CNS contains nucli of the cranial nerves III to XII? - CORRECT
ANSWER>>>>Brain stem
, This is located in the frontal lobe - CORRECT ANSWER>>>>primary motor strip
EPSP causes - CORRECT ANSWER>>>>Depolarization
A patient has hepatic encephalopathy. The EEG is most likely to show - CORRECT
ANSWER>>>>Triphasic waves
You are performing an EEG on a person who has Alzheimer's disease, but is is the very
early stages. You are most likely to see this on the EEG - CORRECT
ANSWER>>>>normal activity
The amplitude of a theta wave on the left temporal is 65uV, and the amplitude of a theta
wave at the same time on the right temporal is 25 uV. This is called - CORRECT
ANSWER>>>>amplitude asymmetry
You are performing an EEG on a patient and notice ECG (EKG) artifact. The montage
to best eliminate ECG is - CORRECT ANSWER>>>>a linked ear referential montage
Syringomyelia - CORRECT ANSWER>>>>abnormal cavity or cyst in the spinal cord
Focal seizures refer to - CORRECT ANSWER>>>>Seizures occurring from one
hemisphere
Wada testing is done to determine - CORRECT ANSWER>>>>speech dominance
Brainstem - CORRECT ANSWER>>>>midbrain, pons and medulla
As you are performing an EEG, you notice a wave that is sharply contoured and stands
out from the background located in the left temporal region. You measure it, and it
measures 90ms in duration. You would call this wave a - CORRECT
ANSWER>>>>sharp
In a normal adult EEG, six to seven hertz theta activity is normally seen - CORRECT
ANSWER>>>>at the onset of drowisness
Inflammation of the brain - CORRECT ANSWER>>>>encephalitis
The major seizure classification system from the ILAE has these major categories -
CORRECT ANSWER>>>>Focal, Unknown onset, Generalized
Changing this could cause artifact to resemble beta activity - CORRECT
ANSWER>>>>high frequency filter
Which of the following is a normal variant mostly recorded from the posterior temporal
region? - CORRECT ANSWER>>>>14 and 6 positive spikes
