chin? - ANS-Less than or equal to 10 kΩ

ANS-The patient has a deviated septum
Why is precise measurement of the head important for a PSG? - ANS-Artifacts can be
caused be improper placement of electrodes, observation of important waveforms
require precise placement and it is also omportant for the identification of sleep onset
and specific sleep stages
All of the following are indications that a patient is entering stage N1 sleep from the
wake stage EXCEPT...... - ANS-the eyes mirror the EEG frequencies which happens in
N2 and N3
All of the following tasks must be completed before beginning the PSG...... - ANS-the
patient signs a consent form, biocalibrations at the begining and the end of each study
are done by the tech and pre-sleep questionnaire is completed by patient
A patient suffering from a seizure must be admitted to the hospital rather than
continuing the sleep study in all of the following circumstances when the patient - ANS-
When a patient has one seizure, the seizure should last more than 5 mins to constitute
an emergency situation wherein the patient is admitted rather than continuing said sleep
study. Any time multi seizures take place the patient should be sent to hospital for
admission
Where should the conductive paste be placed in relation to the gold cup wire? - ANS-
Inside the gold cup
Gloves should be used by the technologist when in contact with all of the following
EXCEPT the - ANS-Hair is the only place where it is not necessary to wear gloves. All
areas that have been cleaned and sanitized with cotton swap gloves must be worn.
Average volume-assured pressure support focuses on maintaining which aspect of the
respiratory process? - ANS-Tidal volume
True statements about how a technologist should respond when a patient experiences a
seizure include all of the following - ANS-Never attempt to touch, hold or restrain a
patient while a patient is having a seizure, remove any objects near by that could injure
the patient,avoid placing anything in the patients mouth or prying the mouth open and
avoid giving liquids during or after the seizure
Following proper prep swabbing, the skin at the prep site should be in which of the
following conditions? - ANS-Slightly abraded and clear of debris
, How often should sleep technologists participate in quality assurance reviews of their
performance? - ANS-Quarterly
If a patient has issues with mouth breathing while using a nasal-only mask, in which
order should the technologist work to alleviate the problem? - ANS-AASM recommends
that you apply or increase heated humidity settings, offer a nasal spray for congestion,
apply a chin strap, attempt to flex the comfort settings and then switch to a full face
mask.
On which muscles are the leg EMG leads placed, and how far apart should they be from
one another? - ANS-Anterior tibialis, 2 cm apart
When should technologists test their equipment for accuracy and function? - ANS-Upon
arriving at the lab
What is the purpose of CPAP interface desensitization? - ANS-Identify the best fitting
mask for the patient, help the patient become more comfortable with the idea of wearing
a mask, to reduce the risk of anxiety and noncompliance with the mask or equiptment
Which channels are necessary for the software montage for a multiple sleep latency
test? - ANS-Chin EMG, EOG monitors, EEG leads & EKG monitors
Which two points on the international 10-20 system of electrode placement are used to
locate F3? - ANS-FZ and F7
When faced with thick, bold, high-frequency artifacts in the EEG, what filter adjustment
should be attempted first during troubleshooting? - ANS-Turn the notch filter on

lowest frequency? - ANS-beta, alpha, theta, and delta
According to guidelines from the American Academy of Sleep Medicine, what is
required to run a multiple sleep latency test?. - ANS-An overnight PSG recording
An example of a sleep technologist acclimating a patient to the testing room includes

granting permission for the technologist to perform the sleep study? - ANS-Do not
perform a sleep study without signed and unedited consent form.
