D. Overlap syndrome (OSA and COPD)
E. None of the above
Answer: E. None of the above
●● Which of the following is true about OSA and HTN?
A. Ambulatory BP is increased in OSA patients primarily due to
increased salt intake associated with elevated ghrelin levels
B. Ambulatory BP normally increases in the early AM before awakening
- this increase is blunted in OSA
C. Untreated OSA is associated with a similar risk of HTN at all severity
levels
D. The risk of HTN in untreated OSA is due to intermittent hypoxia,
sympathetic overactivation, inflammation, and other complex factors

hypoxia, sympathetic overactivation, inflammation, and other complex
factors

C. Delayed sleep phase syndrome
D. Insomnia
E. Obstructive sleep apnea
Answer: D. Insomnia

upper airways than those without sleep apnea but manage to keep an
open airway during wakefulness by:
A. Mouth Breathing

C. Increased blood flow to the soft tissue
D. Frequent bruxing
Answer: B. Increased muscle tone on inspiration
, ●● Key features of sleep apnea as recorded during an in-lab sleep study
include marked reduction or absence of air flow, arousals from sleep,
slowing of heart rate and:
A. Choking or gasping for air
B. Oxygen desaturation
C. Flattening of the nasal pressure signal

●● A 48 year old man is treated with OAT for his moderate OSA. On
repeat sleep testing, his apnea-hypopnea index (AHI) has decreased to 3
events per hour, and he reports resolution of snoring and daytime
