EXAM WITH CORRECT SOLUTIONS.

Which of the following statements is true regarding a modified mallampati classification of the oral pharynx?

• Mallampati II allows visualization of only the hard palate
• Malampati III allows visualization of only the hard palate
• Malampati classifications are taken with the patient sedated

and reclined

• Mallampati classifications of IV have greater odds ratio than

Mallampati classifications of I for severe OSA - correct answer-

• Mallampati classifications of IV have greater odds ratio than

Mallampati classifications of I for severe OSA

What 8 item questionnaire was developed to perioperatively screen for risk of OSA?

A. ESS

B. STOP-BANG

C. MSLT

In the pathophysiology of sleep apnea, airway patency and stability is promoted by which factor? 1 / 4

• | Page

• Increased lung volume
• Shorter mandible
• Increased parapharyngeal fat deposition
• Negative inspiratory pressure
• Reduced pharyngeal muscle dilator activity - correct answer-
• Increased lung volume

Oral appliance therapy commonly provides successful sole therapy for which of the following sleep-related breathing disorders?

• Primary central sleep apnea
• Cheyne-Stoke periodic breathing
• Obesity hypoventilation
• Overlap syndrome (OSA and COPD)
• None of the above - correct answer- E. None of the above

Which of the following is true about OSA and HTN?

• Ambulatory BP is increased in OSA patients primarily due to

increased salt intake associated with elevated ghrelin levels

• Ambulatory BP normally increases in the early AM before

awakening - this increase is blunted in OSA 2 / 4

• | Page

• Untreated OSA is associated with a similar risk of HTN at all

severity levels

• 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

• Insomnia
• Obstructive sleep apnea - correct answer- D. Insomnia

Measurement has shown that patients with sleep apnea have smaller upper airways than those without sleep apnea but

manage to keep an open airway during wakefulness by:

• Increased blood flow to the soft tissue 3 / 4

• | Page

• Frequent bruxing - correct 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:

• Choking or gasping for air
• Oxygen desaturation
• Flattening of the nasal pressure signal
• Flailing of the arms and legs
• Sawtooth waves in the EEG - correct answer- B. Oxygen

Desaturation
