Answer to Question 1

ANS: B
The major use for nitrous oxide is a central nervous system depressant. As such, it is a potent an-esthetic when administered in high concentrations. At very low concentrations (2 to 80 parts per million) combined with oxygen, nitric oxide has been used successfully to treat persistent pul-monary hypertension of the newborn. Carbon dioxide is nonflammable, but it supports combus-tion. Helium-oxygen mixtures decrease the work of breathing by decreasing turbulent airflow.

Answer to Question 2

ANS: C
Helium is the second-lightest element, with a density of 0.165 kg/m3 at 21.1 C and 1 atmos-pheric pressure (atm). Oxygen is slightly heavier than air, with a density of 1.326 kg/m3 at 21.1 C and 760 mm Hg.
