Answer to Question 1

ANS: D
Nitric oxide and nitrogen dioxide combine to form a potent irritant that can cause chemical pneumonitis and pulmonary edema. Nitrous oxide, which is nicknamed laughing gas, can cause brain damage or death if inhaled without a sufficient oxygen supply.

Answer to Question 2

ANS: B
At very low concentrations (2 to 80 parts per million) combined with oxygen, nitric oxide has been used to successfully treat persistent pulmonary hypertension of the newborn. Nitrous oxide is used as a central nervous system depressant (anesthetic). Helium-oxygen mixtures decrease the work of breathing by decreasing turbulent airflow.
