Answer to Question 1

ANS: C
Subtract 10 lb from 38 lb = 28 lb. Convert 28 lb/2.5 lb/L = 11.2 lb. 11.2 lb  860 = 9632 L. Then divide by liter flow: 9632 L/6 L/min = 1605 minutes, or 27 hours.

Answer to Question 2

ANS: B
A flexible diaphragm is attached to a piston to compress gas. As the piston moves down, the di-aphragm is bent outward and gas is drawn through a one-way valve into the cylinder. Upward movement of the piston forces the gas out of the cylinder through a separate one-way outflow valve. Examples of diaphragm compressors are the Air Shields Diapump and the DeVilbiss small nebulizer compressor.

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).
