Answer to Question 1

ANS: C
Formula: PAO2 = (PB PH2O) FIO2 PaCO2 (1.25).
PAO2 = (755 47) 0.60 56 (1.25).
PAO2 = 424.8 70.
PAO2 = 354.8 mm Hg.

Answer to Question 2

ANS: B
Boyle's law states that if the temperature of a gas remains constant, the volume of a gas is in-versely related to its pressure. Therefore, as pressure is exerted on a container, the gas volume within the container decreases.
