Answer to Question 1

ANS: D
Patients who have an increased frequency of awakenings and microarousals have more daytime sleepiness and greater difficulty with daytime functioning than does the general population.

Answer to Question 2

ANS: D
In a laboratory sleep study, several physiologic signals are recorded to determine whether airway closure occurs during sleep and to what extent the closure disturbs sleep continuity and cardio-pulmonary function. An electroencephalogra m (EEG), electrooculogram (EOG), and chin elec-tromyogram (EMG) are obtained for assessment of sleep stage and documentation of sleep dis-ruption due to sleep-related breathing disturbance. Airflow (measured at nose and mouth), venti-latory effort (using inductive plethysmography or piezo belts), cardiac rhythm (with a modified lead II electrocardiogram), and oxygen saturation (measured with pulse oximetry) are included in the standard testing montage.
