CLTM Certification Exam 2026/2027 | Complete Practice Test
Bank | EEG, Seizures, LTM, Patient Safety & Neurodiagnostics
SECTION 1 — PRE-STUDY PREPARATION & NEURODIAGNOSTIC
FOUNDATIONS
1. What is the primary purpose of long-term EEG monitoring in an
epilepsy monitoring unit?
A. Measure peripheral nerve conduction
B. Correlate clinical events with EEG activity over an extended period
C. Replace neurological examination
D. Measure cerebral blood flow
Correct Answer: B
Rationale: LTM allows prolonged EEG and clinical observation so
suspected seizures and other events can be correlated with
electrographic activity.
2. Before beginning an LTM study, which information is most
important to review?
A. Patient's favorite foods
B. Relevant medical history, medications, diagnosis, and reason for
monitoring
C. Insurance company name only
D. Room temperature only
Correct Answer: B
Rationale: The clinical history determines the monitoring strategy and
,helps identify seizure risks, medications, comorbidities, and relevant
precautions.
3. Which patient is most likely to require continuous EEG monitoring?
A. Patient with uncomplicated ankle sprain
B. Patient with altered mental status and concern for nonconvulsive
seizures
C. Patient with stable hypertension only
D. Patient undergoing routine vision screening
Correct Answer: B
Rationale: Altered mental status may represent electrographic seizures
or nonconvulsive status epilepticus, making continuous EEG particularly
useful.
4. Which medication history is particularly important before epilepsy
monitoring?
A. Antiseizure medications
B. Vitamin color preference
C. Shampoo brand
D. Dental insurance
Correct Answer: A
Rationale: Antiseizure medications can suppress seizures and alter EEG
findings. Medication changes may also provoke seizures during
monitoring.
5. What should a technologist do when the patient has difficulty
understanding the monitoring procedure?
,A. Ignore the problem
B. Explain the procedure using language appropriate to the patient's
comprehension level
C. Cancel every study automatically
D. Ask another patient to explain it
Correct Answer: B
Rationale: Effective communication promotes cooperation, reduces
anxiety, and supports patient safety.
6. Which information can be especially valuable when evaluating
suspected seizures?
A. Witness description of the event
B. Patient's shoe size
C. Favorite television program
D. Preferred meal
Correct Answer: A
Rationale: Witness descriptions can provide important semiologic
information, particularly when the patient cannot recall the event.
7. Why should previous neuroimaging be reviewed before LTM?
A. To determine the patient's blood type
B. To identify structural abnormalities that may affect seizure
localization or EEG interpretation
C. To select the patient's meal
D. To calculate body mass index
Correct Answer: B
Rationale: Tumors, strokes, trauma, surgery, and other structural
abnormalities can influence EEG findings and seizure localization.
, 8. A patient has a recent craniotomy. Why is this information
important during EEG?
A. It has no relevance
B. Skull defects can alter scalp EEG amplitude and field distribution
C. It determines electrode color
D. It prevents all EEG recording
Correct Answer: B
Rationale: Skull defects can change the transmission of electrical
activity to scalp electrodes and may produce unusual amplitudes or
focal changes.
9. Which finding should be communicated before monitoring begins?
A. Significant fall risk
B. Favorite music
C. Preferred television channel
D. Clothing brand
Correct Answer: A
Rationale: Fall risk is directly relevant to seizure precautions and patient
safety.
10. What is the purpose of seizure precautions in an EMU?
A. Prevent all EEG abnormalities
B. Reduce injury risk during seizures
C. Increase EEG frequency
D. Prevent sleep
