EEG EXAM PREP LATEST 2026/2027
(QUESTIONS AND 100% CORRECT
ANSWERS)
1.
Which EEG frequency range is typically associated with a relaxed, awake adult with eyes
closed?
a. Delta (0.5–4 Hz)
b. Theta (4–7 Hz)
c. Alpha (8–13 Hz)
d. Beta (13–30 Hz)
Answer: c. Alpha (8–13 Hz)
Explanation: Alpha rhythm is most prominent in relaxed wakefulness, especially with eyes
closed and reduced visual input.
2.
What is the primary purpose of the international 10–20 system in EEG electrode placement?
a. Increase recording speed
b. Standardize electrode placement on the scalp
c. Measure brain oxygen levels
d. Improve patient sedation
Answer: b. Standardize electrode placement on the scalp
Explanation: The 10–20 system ensures consistent, reproducible EEG recordings across patients
and facilities.
3.
,Which EEG pattern is most commonly associated with generalized absence seizures?
a. High-frequency beta activity
b. 3 Hz spike-and-wave discharges
c. Continuous alpha rhythm
d. Burst suppression pattern
Answer: b. 3 Hz spike-and-wave discharges
Explanation: Classic absence seizures show symmetric 3 Hz spike-and-wave complexes.
4.
What is the main function of the EEG calibration procedure before recording begins?
a. Increase electrode impedance
b. Verify accurate signal amplitude and system function
c. Sedate the patient
d. Filter out brain waves
Answer: b. Verify accurate signal amplitude and system function
Explanation: Calibration ensures the EEG system records signals accurately before data
collection.
5.
Which brain wave pattern is most commonly seen during deep sleep (stage N3)?
a. Alpha waves
b. Beta waves
c. Delta waves
d. Mu rhythm
Answer: c. Delta waves
Explanation: Delta waves dominate during slow-wave (deep) sleep.
6.
What is the most likely cause of 60 Hz artifact in an EEG recording?
a. Patient movement
b. Electrical interference from AC power sources
c. Eye blinking
d. Muscle tension
, Answer: b. Electrical interference from AC power sources
Explanation: 60 Hz noise is caused by electrical line interference.
7.
Which electrode is located at the midline frontal region in the 10–20 system?
a. F3
b. Fp1
c. Fz
d. Cz
Answer: c. Fz
Explanation: Fz is the frontal midline electrode in the 10–20 system.
8.
Which EEG feature is most indicative of epileptiform activity?
a. Symmetrical alpha rhythm
b. Spike-and-wave discharges
c. Continuous beta activity
d. Regular theta rhythm
Answer: b. Spike-and-wave discharges
Explanation: Spikes and sharp waves are hallmarks of epileptic activity.
9.
What is the primary role of the EEG technologist during a seizure event?
a. Administer medication
b. Document and ensure accurate EEG recording
c. Diagnose epilepsy
d. Perform surgery
Answer: b. Document and ensure accurate EEG recording
Explanation: Technologists record events and ensure data integrity; diagnosis is done by
physicians.
