Cltm exam newest 2026-2027 actual exam test bank certification for
long term monitoring exam with 2 versions (version a & b) ...
CLTM Exam Overview
The CLTM credential is awarded by ABRET for five years, and
recertification requires 50 continuing education hours within that
period . Candidates must have held the R.EEG.T. credential for at least
one year and have one year of long-term monitoring experience
following credential achievement . Documentation of 50 LTM cases is
also required .
VERSION A
Section 1: EEG Fundamentals & Normal Patterns (Questions 1-20)
Q1. A 30-year-old patient is recorded awake and resting with eyes
closed. The posterior head regions show a rhythmic 10 Hz activity that
blocks when the eyes are opened. How is this pattern classified?
A) Beta activity
B) Mu rhythm
C) Alpha rhythm
D) Theta rhythm
,Answer: C
Rationale: The alpha rhythm is defined as an 8–13 Hz rhythm recorded
over the posterior head regions in a wakeful, relaxed subject with eyes
closed, which attenuates or blocks with eye opening .
Q2. During a routine EEG, a patient becomes drowsy. The technologist
notes the disappearance of the posterior dominant rhythm and the
appearance of low-voltage, mixed-frequency activity. Which sleep stage
does this represent?
A) Stage N1
B) Stage N2
C) Stage N3
D) REM sleep
Answer: A
Rationale: Stage N1 (drowsiness) is characterized by the dropout of the
alpha rhythm and a transition to low-voltage, mixed-frequency (theta)
activity, often with vertex sharp waves appearing near the end of the
stage .
,Q3. A sleep EEG shows brief bursts of 12–14 Hz sinusoidal waves
maximal over the central regions. What is the name of these transient
waveforms?
A) K-complexes
B) Sleep spindles
C) Vertex sharp waves
D) Lambda waves
Answer: B
Rationale: Sleep spindles are brief (0.5–2 seconds) bursts of rhythmic
12–14 Hz activity seen in Stage N2 sleep, generated by thalamocortical
circuits .
Q4. Which of the following best describes the EEG characteristics of
Stage N3 (slow-wave) sleep?
A) Low-voltage, mixed-frequency activity with rapid eye movements
, B) Presence of sleep spindles and K-complexes for >50% of the epoch
C) High-amplitude (>75 μV) delta activity occupying ≥20% of the epoch
D) Continuous alpha rhythm with subtle theta activity
Answer: C
Rationale: Stage N3 is defined by the presence of high-amplitude
(usually >75 μV), slow (0.5–2 Hz) delta activity occupying 20% or more
of a 30-second epoch .
Q5. What is the expected frequency range of the posterior dominant
rhythm (PDR) in a healthy adult?
A) 4–7 Hz
B) 8–13 Hz
C) 14–30 Hz
D) 0.5–4 Hz
Answer: B
