,Which of the following is true about OSA and HTN?
A. Ambulatory BP is increased in OSA patients primarily due to increased salt

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 - CORRECT ANSWER
✔✔ - D. The risk of HTN in untreated OSA is due to intermittent hypoxia,
sympathetic overactivation, inflammation, and other complex factors

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

reasonable dental-medical sleep medicine follow up regimen for this patient?
A. As needed
B. Every 6 months for the first year, then annually
C. Monthly for the first 6 months, then every 6 months
D. Every other year - CORRECT ANSWER ✔✔ - B. Every 6 months for the first year,

Treatment strategies for insomnia in the presence of OSA should make note of
the following true statement:
A. Hypnotics, such as benzodiazepines, can have adverse effects on nocturnal
respiration, thus exacerbating OSA
B. The newer nonbenzodiazepine agents, such as zolpidem and eszopiclone,
appear to increase AHI
C. Cognitive Behavioral Therapy, CBT, is non-pharmacologic and therefore poses
no risk
D. CBT is reported to be more effective for insomnia in the presence of OSA than
when used for insomnia without comorbidities - CORRECT ANSWER ✔✔ - A.
Hypnotics, such as benzodiazepines, can have adverse effects on nocturnal
respiration, thus exacerbating OSA
