Answer to Question 1

ANS: B
Nitric oxide has been shown to be a potent pulmonary vasodilator.

Answer to Question 2

ANS: B
Hyperbaric oxygenation is achieved by having the patient breathe oxygen by mask or through a specially designed hood while being exposed to elevated barometric pressures in the com-pressed-air chamber. Treatment schedules are tailored to the specific needs of the patient. Gener-ally, patients are placed on schedules in which intermittent air-breathing periods of 5 minutes or more are programmed approximately every 20 minutes to prevent oxygen toxicity to the patient.
