Answer to Question 1

ANS: B
The sharp downstroke and return to baseline that normally occurs after the end-tidal point indi-cates inhalation of fresh gas with 0 CO2.

Answer to Question 2

ANS: B
In healthy individuals, the PETCO2 averages 1 to 5 mm Hg less than the PaCO2, or between 35 and 43 mm Hg (approximately 5 to 6 CO2).
