RPSGT PRACTICE TEST #1 WITH CORRECT
DETAILED ANSWERS
what condition would require a full. face mask or oral mask during a CPAP study?
A. The pt is a mouth brather.
B. the pt feels congested.
C. the pt has a deviated septum.
D. the pt is claustrophobic.-correct-answer-C. Most pts suffering from sleep apnea
breathine through their mouth periodically during the night in an attempt to catch
up on deprived oxygen. Healthy pts who are able to inhale through their nose
while awake should be able to inhale through their nose while asleep when
obstructive events are eliminated with CPAP machines. Congestion is a temporary
inconvenience quickly remedied with sprays or humidity setting on the CPAP
machine,not full face masks. most pts who are claustrophobic or anxious are going
to perfet the smallest and least invasive mask. A deviated septum, however, is a
medical condition in which the sinuses and bone have shifted to block the passage
of air either partially or entirely through the nasal passages; in this case, a full fase
mask or oral mask would be necessary.
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.
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.
All of the following tasks MUST be completed before beginning the PSG EXCEPT
A. The Pt signs a consent form
B. biocalibrations are performed by the tech.
C. a pre-sleep questionnaire is completed by the pt.
