Answer to Question 1

ANS: D
The most important factor affecting the degree of airway resistance is the diameter of the air-ways. The mathematical law that determines this fact is Poiseuille's law. A large diameter airway will have low airway resistance and there will be a greater flow of gas. A small diameter airway will have high resistance and there will be a lower flow.

Answer to Question 2

ANS: B
There is no patient trigger noted; therefore, the trigger in this case is time.

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).
