This actual examination reflects the comprehensive neurodiagnostic knowledge required for success on
the ABRET Registration Examination for Electroencephalographic Technologists. It is designed to
evaluate the candidate's understanding of patient preparation and pre-study procedures, EEG
instrumentation and recording strategies, waveform identification, pattern recognition, artifact
detection, and clinical correlation. Questions are structured to assess recall of key concepts, application
of technical knowledge to clinical scenarios, and analysis of EEG patterns in various neurological
conditions. This authentic question bank represents the real exams used in the course and serves as a
comprehensive resource for neurodiagnostic technologists, EEG students, and certification candidates
demonstrating mastery of electroencephalography content for the 2026/2027 academic year.
Domain I: Pre-Study/Patient Preparation (Questions 1–12)
1. A 9-year-old child is scheduled for a routine EEG. The order states “rule out absence seizures.” Which
pre-study action is most important?
A. Instruct the family that the child must remain awake the entire night before the study
B. Review the history for possible absence events and plan for hyperventilation and photic stimulation
C. Apply only temporal electrodes because absence seizures are strictly temporal
D. Cancel the study if the child has taken any medication in the past 48 hours
B. Review the history for possible absence events and plan for hyperventilation and photic stimulation
[CORRECT]
The best answer is B because absence seizures are often activated by hyperventilation, and photic
stimulation is part of the standard activation battery. Reviewing the history allows the technologist to
prepare the appropriate recording strategy.
Correct Answer: B
,2. According to standard infection-control practice in the EEG laboratory, electrodes used on a patient
with known hepatitis B should be:
A. Wiped with alcohol only and reused immediately
B. Cleaned and disinfected according to laboratory protocol for blood-borne pathogens
C. Discarded after a single use without cleaning
D. Soaked in sterile water overnight
B. Cleaned and disinfected according to laboratory protocol for blood-borne pathogens [CORRECT]
This choice is correct because reusable electrodes must undergo thorough cleaning and high-level
disinfection when used on patients with blood-borne pathogens.
Correct Answer: B
3. Which statement best describes the International 10-20 System of electrode placement?
A. Electrodes are placed at 10 % and 20 % intervals of measured head distances
B. Electrodes are placed only over the temporal lobes
C. The system uses fixed millimeter distances regardless of head size
D. Only odd-numbered electrodes are used on the left hemisphere
A. Electrodes are placed at 10 % and 20 % intervals of measured head distances [CORRECT]
The best answer is A because the 10-20 system is based on percentages of the nasion-to-inion and pre-
auricular measurements so that placement is proportional to head size.
Correct Answer: A
4. A patient arrives for an EEG with a recent craniotomy and a large surgical dressing over the right
frontal region. What is the most appropriate action?
A. Remove the dressing without consulting the physician
B. Document the dressing, modify electrode placement as needed, and note any deviations
C. Cancel the study because electrodes cannot be applied
D. Place all electrodes only on the left side of the head
B. Document the dressing, modify electrode placement as needed, and note any deviations [CORRECT]
, This aligns with ABRET standards: the technologist adapts placement when necessary, documents the
reason, and continues the recording.
Correct Answer: B
5. Before applying electrodes, the technologist should measure impedances. Acceptable scalp electrode
impedances are generally:
A. Greater than 50 kohms
B. Less than 10 kohms
C. Exactly 25 kohms for every electrode
D. Irrelevant if the machine is calibrated
B. Less than 10 kohms [CORRECT]
This choice is correct because impedances below 10 kohms reduce artifact and ensure reliable signal
quality.
Correct Answer: B
6. A patient is scheduled for an EEG to evaluate possible encephalopathy. Which piece of history is most
relevant to record before the study begins?
A. Favorite television programs
B. Recent medications, metabolic status, and level of consciousness
C. Preferred room temperature
D. Shoe size
B. Recent medications, metabolic status, and level of consciousness [CORRECT]
The best answer is B because these factors strongly influence the EEG background and help with clinical
correlation.
Correct Answer: B
7. Which of the following is a required element of patient and family education before an EEG?
A. Guaranteeing that the study will diagnose the exact seizure type
B. Explaining the procedure, expected sensations, and the need for cooperation during activation
procedures
C. Advising the family that the child will be sedated for the entire recording
