CLTM (CERTIFICATION IN LONG-TERM MONITORING)
EXAMINATION COMPLETE QUESTIONS AND DETAILED
SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
1. A patient is admitted to an epilepsy monitoring unit for characterization of
recurrent unexplained spells. What is the primary purpose of prolonged video-
EEG monitoring in this situation?
A. To determine serum antiepileptic medication concentrations
B. To correlate clinical behaviors with simultaneous electrographic activity
C. To replace neurological examination with continuous EEG
D. To determine cerebral blood-flow velocity
Answer: B
Rationale: Prolonged video-EEG allows the technologist and physician to correlate
observed clinical events with simultaneous EEG changes, helping classify epileptic
and nonepileptic events.
2. Before beginning an LTM recording, which patient information is particularly
important for determining the appropriate monitoring strategy?
A. Preferred hospital meal schedule
B. Complete seizure history and relevant medication information
C. Patient's favorite television program
D. Previous routine laboratory reference ranges
Answer: B
,Rationale: Seizure semiology, frequency, medications, prior EEG findings, and
clinical history directly influence electrode placement, activation strategies, safety
planning, and monitoring expectations.
3. A patient becomes agitated immediately after electrode application and
repeatedly attempts to remove the leads. What should the technologist do first?
A. Physically restrain the patient independently
B. Ignore the behavior until an electrographic seizure occurs
C. Assess the cause and communicate appropriately with the patient and care
team
D. Immediately terminate the entire admission
Answer: C
Rationale: Patient cooperation and safety are essential; identifying discomfort,
confusion, anxiety, or medical causes allows appropriate intervention without
unnecessarily compromising monitoring.
4. Which finding most strongly supports an electroclinical seizure during video-
EEG monitoring?
A. Rhythmic EEG evolution accompanied by a consistent clinical change
B. Isolated muscle artifact without behavioral change
C. Persistent electrode impedance elevation
D. A movement occurring without any EEG correlate
Answer: A
,Rationale: An evolving rhythmic electrographic pattern temporally associated
with compatible clinical manifestations provides important evidence supporting
an electroclinical seizure.
5. Which electrode placement system is routinely used as the standard
foundation for adult scalp EEG recording?
A. 5-5 system exclusively
B. International 10-20 system
C. Modified ECG system
D. Standard polysomnographic placement
Answer: B
Rationale: The International 10-20 system provides standardized scalp electrode
locations that facilitate reproducible EEG acquisition, interpretation, comparison,
and communication.
6. During electrode application, the technologist discovers that the patient's scalp
is heavily contaminated with oil and hair products. What is the best approach?
A. Apply electrodes without preparation
B. Increase amplifier gain substantially
C. Prepare the scalp appropriately to improve electrode contact
D. Remove all electrodes from the recording montage
Answer: C
, Rationale: Appropriate skin preparation improves electrode contact and reduces
impedance, helping maintain reliable signal quality throughout prolonged
monitoring.
7. Why is video particularly valuable during long-term EEG monitoring?
A. It eliminates the need for EEG interpretation
B. It documents clinical manifestations occurring simultaneously with EEG activity
C. It measures cerebral oxygen consumption directly
D. It automatically identifies every seizure
Answer: B
Rationale: Synchronized video allows clinical behaviors, movements,
responsiveness, and other manifestations to be compared precisely with
concurrent electrographic findings.
8. A patient reports a typical event, presses the event button, and remains fully
responsive. The EEG shows no epileptiform evolution. What should the
technologist do?
A. Delete the event because no seizure occurred
B. Document the event and preserve the corresponding EEG and video
C. Automatically classify the event as psychogenic
D. Increase sensitivity until an abnormality appears
Answer: B
