Answer to Question 1

ANS: C
PAO2 = (Pbar  PH2O) FIO2  PaCO2  0.8; Pbar = 3 atm  760 = 2280 mm Hg.
PAO2 = (2280  47)0.8  40  0.8.
PAO2 = 1786.4  50 = 1736.4 mm Hg.

Answer to Question 2

ANS: D
5 L/min  4 = 20. 20 + 20 = 0.40 FIO2.

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).
