RPSGT Exam Practice Questions and
Correct Answers
Question>> 1.
True statements about how a tech sould respond when a pt experiences a
seizure include all of the following EXCEPT
A. remove any objects nearby that couled injure the pt.
B. hold the pt down, and try to restrain the pt.
C. avoid placing anything in the pts mouth or prying the mough open
D. avoid giving lquids during or just after the seizure.
Correct Answer
B. never attempt to touch, hold or restrain a pt suffering from a seizure.
the tech should remove any objects around the pt that may cause injury
becasue of the uncontrollable movements of the seizure. the tech may
place pillows or other padding in areas where there is a possibiity of
injury.
Question>> 2
how offen should sleep techs participate in quality assurance revies of
their performance?
A. weekly
B. monthly
C. quarterly
D. yearly
Correct Answer
C. weekly and monthly reviews are too offen and can detract or even
discourage a tech if they are pelted with feedback on a regular basis,
regardless of how constructive it is. yearly reviews are more focused on
technical cometencies require for pay increa ses or promotions. Every
quarter the tech should receive a summary of performace in technical
study acquisition and pt interaction, which clearly shows any weaknesses
and strengths in their performance. the tech should always show
improvement in the weak areas each quarter.
,Question>> 3
an artifact that results form salt bridges is most likely caused by
A. incorrect measuring.
B. prepping to large and area.
C. allowing tape or gauze from different locations to make contact.
D. all of the above.
Correct Answer
D. incorrect measurement can cause leads to be too close together, and
prepping a site that is larger than the electrode may allow the prep
solution to connect multiple electodes. Allowing tape or gauze to overlap
can also connect multiple electrodes. if an artiface is severe, the stage of
sleep will be difficult or impossible to discern.
Question>> 4
A pt suffering from a seizure must be admitted to the hospital rather than
continuing the sleep study in all of the followingcircumstances EXCEPT
when the pt:
A. has a single seizure that lasts 3 minutes
B. is persistently confused or unconscious
C. has breathing difficulties.
D. sustains injuries during the seizure.
Correct Answer
A. In the event taht a pt has only one seizure, it must last more than 5
minutes to constitue an emergency situation wherein the pt is admitted
rather thatn continuing the sleep study. any time multiple seizures take
place, the pt sould also be sent to the hospital for admission.
Question>> 5
Which impedance level is considered acceptable for EMG channels, such
as the limbs or chin?
A. Less than or equal to 5 kohms
B. less than or equal to 10 kohms
C. greater than or equal to 15 kohms
D. Less than or equal to 25 kohms.
,Correct Answer
B. No impedance in the whole recording should be over 10 kohms
regardless of type. only EEG leads are ezpected to be 5 or less; muscles-
monitoring electrodes may be as high as but not greater than 10 kohms.
Trace recordings of EEGs and EMGs will look clearer when impedances are
all similar value.
Question>> 6
all of the following are idications that a pt is entering stage N1 slee from
the wake stage EXCEPT
A. there is a reduction in the chin EMG amplitude
B. alpha frequeencies in occipital channels have reduced or stopped
entirely.
C. the eyes roll gently.
D. the eyes mirror the EEG frequencies.
Correct Answer
D. Muscle activity decreases in the chin channel when pts endter N1 sleep
from stage wake. Alpha is on.y present in wake when the eyes are closed,
so as a pt falls asleelp. the alpha frequency is no longer present in the
occipital channels. Gently rolling eyes are an indicator of stage N1. while
eyes are mirroring the EEg are an indication of stage N2 or N3.
Question>> 7
while in the sleep lab, a pt has to do all the following EXCEPT
a. sign a consent form
b. have PSG equiptment attached to the body.
c. remain connected to equipment for at least 6 hrs.
d. remain supine for the entire study.
Correct Answer
D. a medical consent for is always required for any procedure, and a sleep
study is a medical procedure. A pt may not give verbal permission as
consent. for a PSG study to begin, the equipment must be attached, and
for the study to be calid for diagnosis, the pt must remain connected for
no less than 6 hrs. a pt is not required to lay down for the study. in some
cases, pt sleep sitting upright; pt should not be forced to lie down during
, times of stress or anxiety.
Question>> 8
why is precise measurement of the head improtant for PSG?
A. Artifacts can be caused by improper placement of electrodes.
B. Observation of important waveforms required precise electrode
placement.
C. it is improtant for the identification of slee onset and specific sleep
stages.
D. All of the above.
Correct Answer
D. there is no guessing with electrode placement. Artifacts can be caused
by improper placement, or curcial waveforms can be attenuated from
sight in the EEG channels. sleep
identification is not possible when those crucial waveforms are not
present in the PSG. Not all pts have summetrically accurate head shapes.
becasue of this each and every lead locationlocation mush be measured
on its own and not duplicated from a similar measurment on the opposite
side it the head.
Question>> 9
average volume-assured pressrue support (AVAPS)focuses on maintaining
which aspect of the repiratory process?
A. Respiratory rate
B. tidal volume.
C. inspiratory time.
D. expiratory time.
Correct Answer
B. AVAPS focuses primarily on adequate tidal volumes maintained in the
lumgs. the AVAPS is primarily used on pts with repiratory insufficiencies,
such as neuromuscular diseases, COPD or obesity hypoventilation
disorder. the APVAPS estimates the pts tidal volume over a window of tme
and compares it to the set target tidal volume. the target tidal voume is
calculated and set by the tech. the AVAPS detects when the pts breathing
