PRACTICE TEST Q&A FOR GUARANTEED
SUCCESS
If there is no reactive alpha waves or age-appropriate DPR, score wake with
_________ _____________.-correct-answer-Eye Movements
What is the recommended square feet for patient rooms?-correct-answer-140
Electroencephalogram (EEG)-correct-answer-Measure the electrical activity
within the brain through the scalp electrodes to rule out seizure disorders and to
determine characteristics of the sleep-wake state.
Alpha wave frequency-correct-answer-8-13 Hz
Beta wave frequency-correct-answer-13-30 Hz
Delta wave frequency-correct-answer-< 0.5-4Hz
,2|Page
Theta wave frequency-correct-answer-> 4-7 Hz
How many leads are typically used for the EEG channels during a nocturnal PSG?-
although more may be applied to diagnose seizure disorders-correct-answer-6
Electrocardiogram (ECG)-correct-answer-Record and display electrical activity of
the heart through a number of different wave-forms, complexes, and intervals.
P wave-correct-answer-wave in ECG that represents the beginning of electrical
impulses in the Sinus Node, which spread through the atria (muscle
depolarization).
QRS Complex-correct-answer-wave in ECG that represents ventricular muscle
depolarization and atrial repolarization.
T wave-correct-answer-wave in ECG that represents ventricular muscle
repolarization (resting state) as cells regain negative charge.
,3|Page
U wave-correct-answer-wave that represents repolarization of the Purkinje Fibers
Anterior Tibialis Electromyogram (atEMGs)-correct-answer-monitor the electrical
activity in the leg muscles allowing for monitoring of periodic leg movement
during the PSG because electrical activity is absent when the muscle is relaxed and
increases with movement.
Actigraphy-correct-answer-non-invasive method of monitoring human
rest/activity cycles.-monitors gross motor activity (like a fitbit).
True or False? Duration of sleep is not important for the MWT-correct-answer-
True
The physician's orders should be checked before PSG to ensure that the correct
_______ is selected.-correct-answer-Montage
Face Electrodes-correct-answer-used to ground and record eye and chin activity
and include EOG, cEMG, and Ground Electrode.
, 4|Page
Ground Electrode-correct-answer-This electrode does not impact measurements
with modern computerized equipment. It is usually placed in the middle of the
forehead, but can be placed anywhere on the body.
EOG-correct-answer-records vertical and horizontal eye movements and helps to
identify periods of REM sleep.
cEMG-correct-answer-records muscle tone of the chin muscles and helps to
identify REM sleep, during which muscle tone decreases.-can also provide
information on teeth grinding and snoring which causes artifacts.
Pulse Oximetry-correct-answer-continuous or intermittent, uses an external
oximeter that attaches to the patient's finger (or earlobe) to measure arterial
oxygen saturation (SpO2), the percentage of hemoglobin that is saturated with
oxygen.-also indicates the current heart rate.
Normal SpO2 should be over what percent?-correct-answer-95%
___________ _________ is a common cause of inaccurate SpO2 readings.-correct-
answer-Incorrect Position
