A) Nitrous oxide
B) Nitric oxide
C) Betamethasone
D) Terbutaline (Brethine)
B
Feedback:
Inhaled nitric oxide—not nitrous oxide (laughing gas), a vasodilating agent—is believed to reduce sickling by promoting the binding of oxygen to hemoglobin. It is being used in the form of handheld inhalers to abort or relieve pain experienced during sickle cell crises. Betamethasone is a corticosteroid, and terbutaline is not used as an inhaler.
