Answer to Question 1

ANS: A
Volume = Flow  Time, so Flow = Volume  Time. 550 mL = 0.55 L. Flow = 0.55 L  1.2 s = 0.46 L/s  60 = 27.5 L/min.

Answer to Question 2

ANS: B
The maximum safety pressure is usually set by the operator at 10 cm H2O above the peak pressure reached during inspiration.

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).
