Which statement about Nitrous Oxide is true?

Which statement about Nitrous Oxide is true?

• A. It is an inhalant anesthetic and must be administered by an anesthetic machine
• B. It is not an inhalant
• C. It is used as a sole agent for surgical anesthesia
• D. It has no analgesic properties

Answer: (A)

Nitrous oxide is an inhalant anesthetic gas delivered as part of a controlled gas mixture through an anesthesia machine or equivalent delivery system. It requires this equipment to regulate concentration, provide oxygen blending, and scavenge waste gas for safety. It isn’t potent enough to produce surgical anesthesia on its own, so it’s used as an adjunct with other agents, and it does have analgesic properties to aid pain relief during procedures. That combination of being an inhalant delivered by proper equipment and not being used as a sole agent makes the statement true.
