ABRET Practice Exam UPDATED ACTUAL
Exam Questions and CORRECT Answers
Upward - CORRECT ANSWER - The EEG amplifier is designed so that when input 1 is
more negative than input 2, the deflection will be
The characteristic of an amplifier that rejects external interference - CORRECT
ANSWER - Common Mode Rejection is
0.1 Hz - CORRECT ANSWER - Most attenuated by a low frequency filter of 1 Hz
For the deflection to fall (decay) to 67% of the peak deflection - CORRECT ANSWER -
Time constant is defined as the time required
Spike 10mm, wave 6mm - CORRECT ANSWER - An EEG record has three per second
spike/wave discharges. Both the spike and the slow wave have voltages of 100uV. If this
discharge is recorded with a LFF of 5Hz and sensitivity of 10uV/mm, what would the deflection
of the spike and wave be
40% - CORRECT ANSWER - HFF setting 35hz would attenuate 50 Hz muscle activity by
approximately what percentage
Between 25 and 35mm/second horizontal scaling and min of 100 data points/second to
accurately display EEG on monitor screen - CORRECT ANSWER - According to ACNS
guidelines, recording clinical EEG on Digital Media requires monitors to have
10Hz - CORRECT ANSWER - In a record with 10Hz alpha activity, when the display
epoch is changed form 10 seconds per display screen to 20 seconds per display screen, the
frequency of the activity will be
