placement system is the international standard for recording?
A) 10-20 system
B) 10-10 system
C) *10-5 system*
D) Modified combinatorial system

This pattern is most consistent with:
A) Juvenile myoclonic epilepsy
B) Childhood absence epilepsy
C) Lennox-Gastaut syndrome
D) Focal impaired awareness seizure
3. The primary purpose of a referential montage in EEG is to:
A) Minimize muscle artifact
B) Record activity from each electrode relative to a common reference
C) Enhance phase reversals
D) Eliminate EKG artifact
4. In long-term monitoring, what is the minimum recommended sampling rate for adult EEG
according to ACNS guidelines?
A) 128 Hz
B) 256 Hz
C) 512 Hz
D) 1024 Hz
,5. A patient shows rhythmic sharp waves over the left temporal region during sleep. This
finding most likely indicates:
A) Normal sleep variant
B) Benign epileptiform transient of sleep (BETS)
C) Temporal lobe epilepsy
D) Artifact from pulse oximeter
6. The high-frequency filter (HFF) setting of 70 Hz is used primarily to:
A) Reduce muscle artifact
B) Enhance slow waves
C) Eliminate 60 Hz interference
D) Improve EKG visibility
7. During a seizure, the EEG suddenly shows a diffuse voltage attenuation followed by
low-voltage fast activity. This pattern is characteristic of:
A) Atonic seizure
B) Seizure onset pattern in focal epilepsy
C) Myoclonic seizure
D) Electrical status epilepticus in sleep
8. Which of the following artifacts is most commonly caused by poor electrode impedance?
A) EKG artifact
B) *50/60 Hz interference*
C) Eye movement artifact
D) Sweat artifact
9. The primary role of a CLTM during long-term video-EEG monitoring is to:
A) Interpret the EEG findings
B) Prescribe antiepileptic drugs
C) Recognize and document clinical and electrographic seizures
D) Adjust the patient's ventilator settings
10. A patient undergoing reduced antiepileptic drug withdrawal in the EMU develops serial
generalized tonic-clonic seizures without full recovery between events. This condition is called:
A) Simple partial status
, B) Generalized convulsive status epilepticus
C) Pseudostatus epilepticus
D) Nonconvulsive status epilepticus
11. The time constant (TC) in EEG amplifiers affects:
A) High-frequency response
B) Low-frequency response
C) Input impedance
D) Common mode rejection ratio
12. Which of the following patterns is considered a normal variant in adults and is characterized
by 6-7 Hz arciform waves over the temporal regions?
A) Mu rhythm
B) Rhythmic temporal theta of drowsiness (RTTD)
C) Wicket spikes
D) Lambda waves
13. In the ICU, a comatose patient shows bilateral periodic discharges at 1.5 Hz with a triphasic
morphology. The most likely etiology is:
A) Herpes simplex encephalitis
B) Metabolic encephalopathy (e.g., hepatic or renal)
C) Creutzfeldt-Jakob disease
D) Post-anoxic myoclonus
14. The acronym "PSG" during long-term monitoring refers to:
A) Polysomnography
B) Paroxysmal spike group
C) Periodic sharp-wave complex
D) Phase reversal synchronization gradient
15. A technologist notices a sudden increase in EKG artifact on all channels. The most
appropriate immediate action is to:
A) Increase the high-frequency filter
B) Check the patient’s pulse and clinical status
