EEG Board Exam ACTUAL Questions and CORRECT Answers

EEG Board Exam ACTUAL Questions and
CORRECT Answers


EEG Board Exam–Style Practice Examination
Section 1: Instrumentation, Electrode Placement,
and Basic Concepts (Questions 1–25)

Question 1
The standard international EEG electrode placement system is known
as:
A. 5–10 system
B. 10–20 system
C. 20–40 system
D. Bipolar placement system
Correct Answer: B. 10–20 system
Explanation:
The International 10–20 System is the standard method for positioning
scalp electrodes using proportional measurements based on anatomical
landmarks.


Question 2

,In the 10–20 system, the letter “F” represents:
A. Frontal region
B. Functional electrode
C. Facial electrode
D. Frequency channel
Correct Answer: A. Frontal region
Explanation:
Electrode letters correspond to anatomical areas:
• F = frontal
• C = central
• P = parietal
• O = occipital
• T = temporal


Question 3
The reference electrode is used to:
A. Increase amplifier gain
B. Provide a comparison point for voltage measurement
C. Eliminate all artifacts
D. Replace scalp electrodes
Correct Answer: B. Provide a comparison point for voltage
measurement

,Explanation:
EEG measures voltage differences between electrodes. A reference
electrode provides a stable comparison point.


Question 4
The normal adult posterior dominant rhythm is typically:
A. 1–3 Hz
B. 4–7 Hz
C. 8–13 Hz
D. 20–30 Hz
Correct Answer: C. 8–13 Hz
Explanation:
The posterior dominant rhythm (alpha rhythm) is usually 8–13 Hz in
relaxed awake adults with eyes closed.


Question 5
Which electrode placement system uses additional electrodes between
the standard 10–20 positions?
A. 10–10 system
B. Bipolar montage
C. Referential montage
D. Average montage
Correct Answer: A. 10–10 system

, Explanation:
The 10–10 system increases electrode density and improves localization
of EEG abnormalities.


Question 6
A high electrode impedance may result in:
A. Improved signal quality
B. Increased artifact susceptibility
C. Increased seizure detection
D. Elimination of electrical noise
Correct Answer: B. Increased artifact susceptibility
Explanation:
Poor electrode contact increases noise and can introduce artifacts into
the recording.


Question 7
The EEG amplifier primarily functions to:
A. Generate brain waves
B. Amplify small voltage differences
C. Remove all biological activity
D. Produce patient stimulation
Correct Answer: B. Amplify small voltage differences
