Introduction
This structured EEG BOARD EXAM format for 2026–2027 provides the complete layout for generating high-quality exam-style
questions with correct answers and rationales. It emphasizes foundational neurodiagnostic principles, accurate waveform
interpretation, evidence-based clinical interventions, and patient safety protocols critical to professional nursing and
neurodiagnostic practice and successful national board certification.
Answer Format
All correct answers must appear in bold and cyan, accompanied by concise rationales explaining safety/clinical reasoning,
protocol adherence, and why alternative options are less appropriate. STRICT RANDOMIZATION PROTOCOL: The placement of the
correct choice (A, B, C, or D) MUST be strictly and unpredictably randomized for every single question. Do not use predictable
patterns, avoid consecutive identical letters, and ensure an even distribution across all options to guarantee an authentic exam
simulation.
1. Before beginning an EEG study, the technologist should verify the patient's:
A. Favorite color
B. Social security number
C. Name, date of birth, and referring physician's order
D. Insurance information only
Correct Answer: C. Name, date of birth, and referring physician's order
Rationale: Accurate patient identification and verification of the physician's order are essential for patient safety and proper
documentation.
2. Which of the following is a contraindication for performing a routine EEG?
A. Patient on anticonvulsants
B. History of migraine
C. Open head wound at electrode sites with active infection
D. Recent seizure
Correct Answer: C. Open head wound at electrode sites with active infection
,Rationale: Active infection at electrode placement sites is a contraindication because it risks spreading infection and
compromising the study.
3. The technologist should instruct the patient to:
A. Apply gel to the scalp
B. Avoid hair products and come with clean, dry hair
C. Wear heavy makeup
D. Wash hair with conditioner the morning of the study
Correct Answer: B. Avoid hair products and come with clean, dry hair
Rationale: Clean, dry hair without oils, gels, or sprays ensures good electrode contact and reduces artifact.
4. Prior to electrode application, the technologist should:
A. Use only one reference electrode
B. Measure the head using the 10-20 system and mark electrode sites
C. Apply electrodes without skin prep
D. Skip measurement if the patient is in a hurry
Correct Answer: B. Measure the head using the 10-20 system and mark electrode sites
Rationale: Accurate 10-20 system measurement is critical for reproducible and standardized electrode placement.
5. Skin preparation for EEG electrodes typically involves:
A. Shaving the entire scalp
B. Using only soap and water
C. Abrading the skin lightly with a mild abrasive and cleaning with alcohol or conductive paste
D. Applying lotion
Correct Answer: C. Abrading the skin lightly with a mild abrasive and cleaning with alcohol or conductive paste
Rationale: Mild abrasion and cleaning reduce impedance and improve signal quality while minimizing skin irritation.
6. The technologist should obtain informed consent or verify:
A. That the patient understands the procedure and has given permission (or legal representative has)
B. Only the patient's age
C. Nothing is required
D. The patient's political affiliation
Correct Answer: A. That the patient understands the procedure and has given permission (or legal representative has)
Rationale: Informed consent or verification of understanding and permission is a standard pre-study safety and ethical
requirement.
7. Which patient history information is most critical before an EEG?
A. Favorite foods
, B. Pet's name
C. Hobbies
D. Current medications, seizure history, and any recent head injury or surgery
Correct Answer: D. Current medications, seizure history, and any recent head injury or surgery
Rationale: Medication history (especially anticonvulsants and sedatives) and recent events significantly affect EEG interpretation.
8. Electrode impedances should ideally be:
A. Ignored during the study
B. Greater than 100 kΩ
C. Less than 5-10 kΩ and balanced across electrodes
D. Exactly 50 kΩ for all
Correct Answer: C. Less than 5-10 kΩ and balanced across electrodes
Rationale: Low and balanced impedances (<5-10 kΩ) are required for optimal signal quality and to minimize 60 Hz artifact.
9. When preparing a pediatric patient, the technologist should:
A. Explain the procedure in age-appropriate language and involve parents/guardians
B. Skip explanations to save time
C. Use restraints without explanation
D. Use adult electrode placements only
Correct Answer: A. Explain the procedure in age-appropriate language and involve parents/guardians
Rationale: Age-appropriate communication and parental involvement reduce anxiety and improve cooperation and data quality.
10. The technologist should check the EEG machine for:
A. Nothing - just plug it in
B. Proper calibration, filter settings, sensitivity, and paper speed or digital equivalents before starting
C. Only the time display
D. The color of the screen
Correct Answer: B. Proper calibration, filter settings, sensitivity, and paper speed or digital equivalents before starting
Rationale: Verification of equipment settings ensures accurate recording and allows comparison with previous studies.
11. A patient with a known latex allergy requires:
A. Cancellation of the study
B. Standard electrodes
C. Non-latex electrodes, gloves, and head cap
D. No special precautions
Correct Answer: C. Non-latex electrodes, gloves, and head cap
, Rationale: Latex-free supplies must be used to prevent allergic reactions.
12. Pre-study documentation should include:
A. Nothing written
B. The technologist's lunch order
C. Only the patient's name
D. Patient identification, clinical history, medications, and any special instructions
Correct Answer: D. Patient identification, clinical history, medications, and any special instructions
Rationale: Complete pre-study documentation provides context for interpretation and supports continuity of care.
13. The technologist should ask about:
A. Recent caffeine intake, sleep deprivation status, and last meal
B. Political views
C. Nothing personal
D. The patient's favorite movie
Correct Answer: A. Recent caffeine intake, sleep deprivation status, and last meal
Rationale: Caffeine, sleep status, and recent meals can significantly affect EEG background and epileptiform activity.
14. For a patient with a scalp wound or recent surgery, the technologist should:
A. Cancel the study
B. Use extra gel on the wound
C. Avoid the affected area if possible, document the issue, and consult the ordering physician if necessary
D. Place electrodes directly on the wound
Correct Answer: C. Avoid the affected area if possible, document the issue, and consult the ordering physician if necessary
Rationale: Avoidance of compromised areas and proper documentation protect the patient and maintain study validity.
15. The 10-20 system measurement from nasion to inion is used to determine:
A. The patient's age
B. Nothing
C. Electrode color only
D. The longitudinal placement of midline electrodes (Fz, Cz, Pz, Oz)
Correct Answer: D. The longitudinal placement of midline electrodes (Fz, Cz, Pz, Oz)
Rationale: Nasion-inion measurement determines the anterior-posterior placement of the central midline electrodes.
16. Which of the following is part of pre-study safety checks?
A. Asking about vacation plans
B. Nothing - safety is not a concern
