RPSGT || 100% Correct Solutions.
(2) During an MSLT, how is sleep onset defined? correct answers The first 30-second epoch in
which there is more than 15 seconds of cumulative sleep
(3) Where are the reference electrodes M1 and M2 placed on the head? correct answers In the
pre-auricular area behind the ear or on the earlobes
(4) What is a false statement about the process of bio-calibrations? correct answers Bio-
calibrations are done only at the beginning of the study
(6) What is the recommended minimum/maximum differential for IPAP and EPAP settings
during a BiPAP titration? correct answers 4-10 cmH2O
(9) An artifact that results from salt bridges is most likely caused by... correct answers Incorrect
measuring, prepping too large an area, and allowing tape or gauze from different locations to
make contact
(15) What is NOT an indication that a patient is entering stage N1 sleep from the wake stage?
correct answers The eyes mirror the EEG frequencies
Correct:
There is a reduction in chin EMG amplitude. Alpha frequencies in occipital channels have
reduced or stopped entirely. The eyes roll gently.
(22) Following proper prep swabbing, the skin at the prep site should be in which condition?
correct answers Abraded and clear of debris
(23) How often should sleep technologists participate in quality assurance reviews of their
performance? correct answers Quarterly
(25) On which muscle are the leg EMG leads placed, and how far apart should they be from one
another? correct answers Anterior tibialis, 2 cm apart
(31) What is the correct order of EEG waveform from highest to lowest frequency? correct
answers Beta, alpha, theta, and delta
(35) A list of important statistics, averages, and details observed during the entire study is known
as a... correct answers Technologist's summary
(46) Is it possible to designate a patient as having hypo-ventilation without PaCO2 data? correct
answers No, persistent SpO2 desaturations are not sufficient
(49) What is NOT an acceptable way to ensure that the morning paperwork is filled out before
the patient leaves the lab? correct answers Force the patient to fill out the paperwork while the
technologist watches
, Correct:
Ask the patient to fill out the paperwork before getting dressed. Make sure the paperwork is
clearly displayed and explained to the patient after unhooking them. Inform the patient to remain
in the lab until the technologist clears them to leave.
(53) Which accurately describes the placement location of left eye lead? correct answers 1 cm
below the left outer canthus
(55) The artifacts that are most likely to cause high amplitude, low-frequency waves seen on the
EEG are... correct answers Respiratory artifacts
(56) Which of the following low-frequency/high-frequency filter settings appropriately isolate
the significant frequency ranges in the EEG channels? correct answers 0.3/35
(57) Delta waves must be how many micro-volts in amplitude to count toward stage N3 sleep
percentages? correct answers 75 micro-volts
(59) What is NOT an acceptable result of PAP titration? correct answers It does not reduce the
RDI to 10 or less but reduces the RDI by 50% from baseline in severe patients
Correct:
It reduced the RDI to less than 5 for at least a 15-min duration and should include supine REM
sleep at the selected pressure that is not continually interrupted by spontaneous arousals or
awakenings. It reduces the RDI to 10 or less or by 50% of the baseline RDI less than 15 and
should include supine REM sleep that is not continually interrupted by spontaneous arousals or
awakenings. It reduces the RDI to less than 5 for at least a 15-min duration without supine sleep
seen at the selected pressure
(61) What is the recommended highest IPAP setting for a patient over the age of 12 years?
correct answers 30 cm
(62) Which of the following arrhythmias qualifies as a medical emergency? correct answers
Third-degree atrioventricular block
(63) In what format should "lights on/lights out" be recorded in the technologist's documentation
notes? correct answers Epoch number
(64) What is an accurate difference in scoring pediatric RERAs from adult RERAs? correct
answers Pediatric rules require 50% or more reduction in flow, flattening of the flow waveform
and snoring or labored breathing, and do not require an arousal to score a RERA
(69) What is the proper way to score a major movement-dominated epoch in a recording? correct
answers If an alpha rhythm is present for part of the epoch, score as stage wake. If no alpha
rhythm can be discerned, but an epoch of stage wake either precedes or follows the epoch with a
