ABRET PRACTICE QUESTIONS AND ANSWERS
1. What additional electrodes could be placed to help decipher between artifact
and cortical activity in this sample?
EOG electrodes
2. Brain Abcess
Focal polymorphic delta activity.
3. 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
4. An abbreviated 10-20 placement, respiration, ECG and EOG monitors should be
used when recording...
Neonates
5. Sphenoidal electrodes are used to record activity from the
... Anterior temporal lobes
6. Why is it not best practice to allow an outpatient to sleep throughout the entire EEG
recording?
Unable to evaluate the patient's background rhythm.
7. Cortical EEG recordings can be obscured in patients who are tense and anxious due to
... Myogenic Artifact
8. What type of monitoring would be useful in an EEG patient experiencing
syncope? ECG
9. What additional monitoring should be done in a middle age patient who repeatedly
alerts from sleep during the EEG?
Respiration
10. Which of the following is important for the technologist to document in order to aid in
interpretations?
The patient was awake and alert during the recording
11. A slow wave focus is best seen with...
LF 0.3 Hz, paper speed 15 mm/sec
12. A waveform of 0.5 Hz can be best enhanced with a filter of
LF 0.3 Hz
