RPSGT- EXAM 3 QUESTIONS AND ANSWERS
A collection of electrode derivations used in a sleep study is called a: - Answers -
montage
Which of the following terms describes external or environmental time cues? - Answers
- Zeitgeber.
At what percentage of the distance from the nasion to the onion is Fz located up from
the nasion? - Answers - 30 %
Which of the following techniques best promotes patient compliance with PAP therapy?
- Answers - Management of interface problems and leaks, and nasal congestion and
airway dryness.
During standard polysomnography, the electrooculogram high frequency filter should be
set at: - Answers - 35 Hz
A combination of electrical companents designed to increase power, voltage or current
of a signal is a(n): - Answers - amplifier.
Prior to lights out you would explain all of the following EXCEPT: - Answers - the need
to lie supine throughout the entire study.
A simple self-administered questionnaire that is used to assess a patient's perception of
sleepiness is known as the: - Answers - Epworth Sleepiness Scale.
According to the principes of differential amplification, electrical interference can best be
prevented if: - Answers - electrode impedances are similar.
You begin a sleep study on a patient at 9:30 pm. At 10:45 pm, you think to yourself that
the patient should be in stage N3 by now, but the EEG does not demonstrate this. You
realize that the low frenquency filter is set at 3 Hz. The appropriate instrumentation
change would be to : - Answers - decrease the low frequency filter to 10 Hz.
The best description of the PAP Mode: APAP (Automatically titrating airway pressure) is
that APAP maintains: - Answers - varying pressure levels through the night to keep the
airway open.
The indications for bi-level positive airway pressure are all of the following EXCEPT: -
Answers - restricted total lung capacity.
After a successful CPAP titration, the optimal pressure is established at 11 cm H2O. All
respiratory events were eliminated. The oxygen saturation, via pulse oximetry, remained
