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.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
