CPSGT Practice Test 2 UPDATED ACTUAL
Questions and CORRECT Answers
The goals of PAP therapy include all of the following EXCEPT to
a.improve diminished lung capacity.
b. eliminate flow limitations in the upper airway.
c. eliminate excessive daytime somnolence.
d. eliminate snoring. - CORRECT ANSWER A: Improve diminished lung capacity. The
CPAP and BiPAP used in the sleep lab are non-invasive respiratory therapies that do not have
effects on patient's lung capacity or tidal volumes. The focus of the PAP devices is to maintain
the structural integrity of the airway, especially the upper airway, to prevent collapses that result
in obstructive apneas and snoring.
To ensure REM sleep has a chance to occur during a multiple sleep latency test nap, how long
should that nap continue?
a. 25 minutes following "lights out."
b. 15 minutes following sleep onset.
c. 15 minutes following "lights out."
d. 20 minutes following sleep onset - CORRECT ANSWER B: 15 minutes following sleep
onset. According to the guidelines of the American Academy of Sleep Medicine for the
operation of a multiple sleep latency test (MSLT), a MSLT nap continues for 15 minutes
following sleep onset. The first thing for which the MSLT is looking is to see if the patient is
capable of falling asleep in a 20- minute space of time. If a patient does not fall asleep within 20
minutes, the nap is ended. If the patient falls asleep during the 20-minute window, the nap
continues for 15 more minutes from that time to see if REM can be reached shortly after sleep
onset.
Staging choices for infants include which of the following combinations?
a. Active REM sleep and quiet sleep.
b. Indeterminate sleep, wake, and quiet sleep.
c. Active REM sleep and delta sleep.
,d. Indeterminate sleep, active REM sleep, and quiet sleep. - CORRECT ANSWER D:
When scoring infant sleep studies, the only available options for sleep stage scoring are
indeterminate sleep, active REM sleep, and quiet sleep. At around 6 months of age, pediatric
scoring rules become more applicable as waveforms, such as sleep spindles, become manifested.
An infant's EEG is so unlike the pediatric and adult waveforms that identifying the standard
sleep stages would be impossible.
Heated humidity can possibly remedy which of the following conditions seen in some patients?
a. Patient complains of being cold.
b. Patient mouth-breathes because of nasal congestion.
c. Patient complains of dry throat or nose.
d. Both B and C. - CORRECT ANSWER D: When scoring infant sleep studies, the only
available options for sleep stage scoring are indeterminate sleep, active REM sleep, and quiet
sleep. At around 6 months of age, pediatric scoring rules become more applicable as waveforms,
such as sleep spindles, become manifested. An infant's EEG is so unlike the pediatric and adult
waveforms that identifying the standard sleep stages would be impossible.
What is the standard length of time of each epoch during the scoring of stages in a PSG?
a. 30 seconds.
b. 45 seconds.
c. 3 minutes.
d. 10 minutes. - CORRECT ANSWER A: According to guidelines of the American
Academy of Sleep Medicine entitled, "The Visual Scoring of Sleep in Adults," scoring by 30-
second epochs was retained from the Rechtshaffen and Kales process of scoring sleep studies.
The reason for the either 20- or 30-second view of the EEG is the ability to see the vertex spike
waves, complexes, and spindles clearly enough to confirm sleep staging
An alternating EEG pattern seen during quiet sleep in a newborn infant, consisting of both
highand low-voltage activity is termed
a. active sleep.
b. trace alternant.
c. sawtooth waves.
, d. slow-wave sleep - CORRECT ANSWER B: Trace alternant is the NREM sleep for
infants that diminishes and becomes nonexistent between 3-6 weeks of age in healthy infants.
This pattern is found in an infant's slow-wave sleep and after the first month of life; it is
gradually replaced with sleep spindles.
Electrical safety requires all of the following actions from a technician EXCEPT
a. checking the conditions of wires to assure none are frayed or damaged.
b. the application of a ground placed with the pulse oximetry probe. c. the application of a
ground lead wire placed on the head for the PSG.
d. keeping liquid away from all electrical components - CORRECT ANSWER B: the
application of a ground placed with the pulse oximetry probe. Pulse oximetry devices are very
low-voltage, passive electrical devices that do not require a ground to avoid patient electrocution.
Pulse oximetry is a direct current electrical device. Frayed and exposed wires, improperly
grounded surface electrodes, as well as wet equipment can electrocute a patient.
What physiological effects does CPAP have on the body?
a.
b. Improves pulmonary function.
c. Increases blood-gas exchange efficacy.
d. Controls respiratory rate. - CORRECT ANSWER A: Splints the airway to allow breaths
to pass through without occlusion. The CPAP will not increase pulmonary function in patients,
and it will not improve the rate at which oxygen is transferred into the heart. However, CPAP
supports the structural integrity of the airway when patients fail to hold the airway open with
their own muscles. By preventing a collapse of the airway, an apneic patient will never have to
struggle to reopen their airway while asleep.
Before a technician begins cardiopulmonary resuscitation on a patient, basic life support
procedures require the technician to do which of the following?
a. Contact a nurse for assistance.
b. Verify the patient's unresponsiveness.
c. Check the patient's pulse.
d. Listen for the patient's breath - CORRECT ANSWER B: Verify the patient's
unresponsiveness. According to "Basic Life Support Procedures" from the American Heart
