Answer to Question 1

ANS: C
The electromyogram can be used to monitor activation of the muscles that expand the upper air-way and to monitor the intercostal muscles as an alternative to assess respiratory activity.

Answer to Question 2

ANS: C
The apnea hypopnea index is calculated by taking the sum of the total number of apneas and the number of episodes of hypopnea. The total is then divided by the number of hours of sleep.
