CLTM & EEG Board Prep 2026/2027 | Complete Practice
Questions, Correct Answers & Detailed Rationales
SECTION 1 — PRE-STUDY PREPARATION & NEURODIAGNOSTICS
1. What is the primary purpose of long-term EEG monitoring (LTM)?
A. To replace neurological examination
B. To correlate EEG activity with clinical events over an extended period
C. To measure intracranial pressure
D. To determine cerebral blood flow
Correct Answer: B
Rationale: LTM allows prolonged observation of EEG activity and clinical
behavior, making it particularly useful for seizure characterization, event
correlation, and diagnosis.
2. Which information is MOST important before beginning an LTM
study?
A. Patient's preferred television channel
B. Relevant clinical history and reason for monitoring
C. Patient's favorite meal
D. Hospital parking location
Correct Answer: B
Rationale: The indication and clinical history guide recording strategy,
electrode selection, monitoring precautions, and interpretation.
3. A patient admitted to an epilepsy monitoring unit is being
evaluated for recurrent unexplained episodes. What is an important
goal of LTM?
,A. Determine blood type
B. Capture typical events and correlate them with EEG
C. Measure muscle strength
D. Diagnose all psychiatric disorders
Correct Answer: B
Rationale: Capturing habitual events and determining whether they
have an electrographic correlate is a major indication for EMU
monitoring.
4. Which medication history is particularly important during LTM?
A. Only vitamins
B. Antiseizure medications and recent medication changes
C. Only topical medications
D. Only antibiotics
Correct Answer: B
Rationale: Antiseizure medications can substantially influence seizure
occurrence and EEG activity. Medication reduction may also be part of
an epilepsy-monitoring protocol.
5. Why should the technologist establish rapport with the patient
before recording?
A. To replace informed consent
B. To encourage cooperation and improve monitoring quality
C. To determine the EEG diagnosis
D. To prescribe medication
Correct Answer: B
Rationale: Clear communication promotes cooperation, accurate event
reporting, and patient safety.
,6. Which finding should be communicated before electrode
application?
A. Patient's favorite music
B. Significant scalp lesion or surgical defect
C. Patient's shoe size
D. Meal preference
Correct Answer: B
Rationale: Scalp abnormalities or surgical defects can affect electrode
placement, signal quality, interpretation, and skin safety.
7. A patient has a recent craniotomy. Why is this information
important to the EEG technologist?
A. It determines blood type
B. It may alter EEG amplitude and electrode placement considerations
C. It eliminates the need for video
D. It prevents all seizures
Correct Answer: B
Rationale: Skull defects can alter electrical field distribution and may
require modified placement and documentation.
8. Which structure is primarily associated with memory formation?
A. Hippocampus
B. Medulla
C. Cerebellar vermis
D. Occipital pole
, Correct Answer: A
Rationale: The hippocampus is a key structure in memory formation
and is commonly involved in temporal lobe epilepsy.
9. The primary motor cortex is located in the:
A. Postcentral gyrus
B. Precentral gyrus
C. Occipital lobe
D. Temporal pole
Correct Answer: B
Rationale: The precentral gyrus contains the primary motor cortex.
10. The primary somatosensory cortex is located in the:
A. Precentral gyrus
B. Postcentral gyrus
C. Superior temporal gyrus
D. Cingulate cortex
Correct Answer: B
Rationale: The postcentral gyrus contains the primary somatosensory
cortex.
11. Which lobe is primarily responsible for processing visual
information?
A. Frontal
B. Temporal
C. Parietal
D. Occipital
