1 A side effect of CPAP is:
A Aerophagia
B Hypertension
C Bradycardia
D Hypotension
Why A is correct: Aerophagia (swallowing of air) is a common side effect of CPAP therapy.
B — Hypertension is not a typical side effect of CPAP.
C — Bradycardia is not a typical side effect.
D — Hypotension is not a typical side effect.
,2 According to RECOMMENDED guidelines, Adaptive Servo-Ventilation can be
considered during a titration study when a down titration:
A Has not eliminated Cheyne-Stokes respiration or central emergent apneas
B Has eliminated obstructive apneas
C Has reduced AHI to less than 5
D Has eliminated snoring
Why A is correct: ASV can be considered when down titration has not eliminated Cheyne-
Stokes respiration or central emergent apneas.
B — ASV is for central events, not obstructive.
C — AHI reduction is not the criterion for ASV.
D — Snoring elimination is not the criterion.
3 Which of the following is MOST likely to occur due to an improperly fitting PAP
interface?
A Conjunctivitis
B Pneumonia
C Otitis media
D Sinusitis
Why A is correct: Improperly fitting PAP interfaces can cause conjunctivitis due to air leaks
irritating the eyes.
B — Pneumonia is not directly caused by interface fit.
C — Otitis media is not typically caused by interface fit.
D — Sinusitis may be related but conjunctivitis is more common.
, 4 The BEST candidate for oral appliance therapy would have:
A Mild OSA
B Moderate OSA
C Severe OSA
D Central sleep apnea
Why A is correct: The best candidate for an oral appliance is a patient with mild OSA.
B — Moderate OSA may be treated but mild is ideal.
C — Severe OSA may require PAP therapy.
D — Oral appliances are not effective for central apnea.
5 According to RECOMMENDED guidelines, CPAP should be increased at an interval
no less than:
A 5 minutes
B 10 minutes
C 15 minutes
D 20 minutes
Why A is correct: CPAP should be increased at an interval no less than 5 minutes.
B — 10 minutes is longer than the minimum.
C — 15 minutes is longer than the minimum.
