False
TRUE/FALSE
Enuretic episodes can occur in all stages of sleep.
True
TRUE/FALSE
Enuresis may be associated with OSA.
True
TRUE/FALSE
The majority of enuretic episodes occur during the first third of the night.
True
An awake "eyes closed" alpha rhythm is best recorded from which of the following areas of the brain?
Occipital
A high-amplitude, low-frequency artifact is noted in an EEG channel. Which of the following is the most likely cause?
a) EKG
b) EMG
c) respiration
d) electrical
c) Respiration
TRUE/FALSE
An arousal in REM sleep requires a 3-second or longer shift in EEG frequency.
True
TRUE/FALSE
An arousal in REM sleep requires a K-complex.
False
TRUE/FALSE
An arousal in REM sleep requires an increase in chin muscle tone.
True
Parameters required for inclusion of limb movement in a PLMS sequence include all of the following EXCEPT:
a) duration
b) amplitude
c) arousals
d) interval
c) Arousals
Ectopic beats that originate below the bundle of His and occur earlier than the normally expected beat are called...?
PVC's
In a 30-second epoch, sleep spindles occurred at the 10th and 20th second points. The preceding and succeeding epochs were REM. This epoch is scored as which stage?
REM
The best way to eliminate electrical interference from the extensor digitorum channel during physiological calibrations may require which of the following actions?
a) Activate the notch filter.
b) Decrease the high-frequency filter to 35 Hz.
c) Replace the recording electrodes.
d) Adjust the low-frequency filter.
c) Replace the recording electrodes.
A technologist is running an all-night PSG on a patient with no prior history of EKG abnormalities. The tech notices that the patient's EKG develops an occasional "dropped" or "missed" QRS. Upon closer investigation, the tech sees the P wave and QRS occur progressively further apart until a QRS is "skipped"; this is a repeating pattern. This defines which dysrhythmia?
Second-degree AV block, type 1
TRUE/FALSE
For a normal young adult, REM sleep is usually 20 to 25% of sleep.
True
TRUE/FALSE
For a normal young adult, stage 2 sleep generally comprises about 25 of sleep.
False
TRUE/FALSE
For a normal young adult, NREM sleep and REM sleep alternate with a period of near 90 minutes.
True
For a normal young adult, REM sleep predominates in the last third of the night.
True
What is the low frequency filter used for?
Eliminating unwanted slow frequencies
Which waveforms occur at their maximum amplitude in the central region of the brain?
Spindles and vertex sharp waves
The purpose of the time axis check is to verify what?
Vertical pen alignment
According to ASDA guidelines, if a patient does not fall asleep during an MSLT nap, the nap should be terminated after how many minutes?
After 20 minutes
