CPSGT Exam - Basic Information: Questions With
Comprehensive Solutions
The distance from pre-auricular crease to pre-auricular crease is 35 cm. What
is the distance in cm between C3 and Cz?
a. 3.5 b. 7 c. 14 d. 28 Right Ans - b. 7
According to RECOMMENDED guidelines, unattended portable monitoring
devices must include:
a. Actigraphy b. Blood oxygenation c. ECG d. One channel of EEG Right Ans -
b. Blood oxygenation
Which of the following is an example of an electrical artifact?
a. EMG b. Pulse c. 50/60 Hz d. Sweat Right Ans - c. 50/60 Hz
4. Which arrhythmia would require activation of the Emergency Response
System?
a. Bradycardia b. Premature ventricular contraction c. Sinus tachycardia d.
Ventricular fibrillation Right Ans - d. Ventricular fibrillation
K complexes and sleep spindles are most prevalent in what stage of sleep?
a. N1 b. N2 c. N3 d. REM Right Ans - b. N2
What is the minimum duration in seconds of an apnea?
a. 5 b. 10 c. 15 d. 20 Right Ans - b. 10
According to RECOMMENDED titration guidelines, CPAP should be increased
after observing at least:
a. 2 obstructive apneas b. 3 RERAs c. 5 hypopneas d. 5 minutes of
unambiguous snoring Right Ans - a. 2 obstructive apneas
, Which PAP interface is the BEST option for a patient with a nasal obstruction?
a. Nasal b. Nasal pillows c. Nasal with chin strap d. Oronasal Right Ans - d.
Oronasal
Nasal mask Right Ans - -Covers only the nose
-Most common mask worn w/ CPAP
-Typically tolerated well by most pts
-Since the mouth is not covered, the biggest issue is LEAKAGE THROUGH THE
MOUTH (w/ mouth breathers)
-Can also cause nasal dryness and nasal drainage
Oronasal mask Right Ans - -Covers mouth and nose
-Functions similarly to nasal mask
-Since mouth is covered, it provides a BETTER SEAL and leakage isn't as big of
a problem
-Aspirations and regurgitation can be potential problems
-Asphyxiation if the machine, electricity, or gas sources were to fail is another
potential problem --> most masks of this type have safety valves to prevent
this from occurring
Nasal pillows Right Ans - -Prongs that are inserted into the nose
-Resembles the nasal mask but is much smaller
-Common interface in CPAP therapy but would not be recommended for
BiPAP
-Since it is the smallest interface, it's typically the most comfortable for pts
-Some complications include NASAL CONGESTION, dry mouth, and nose
bleeds
-Gas leakage through the mouth is also a potential problem (similar to the
nasal mask)
Full face mask Right Ans - -Covers entire face
-It is the largest interface, meaning it is typically the most uncomfortable for
pts
-Full face mask is typically indicated when there is significant mouth
breathing in the pt
-Often occurs during acute exacerbation of COPD
-Since it covers the entire face, it usually can provide a better-quality
ventilation in terms of improved minute ventilation and blood gas results
