Which of the following procedures can a dental assistant II monitor under nitrous oxide?

The ability of a dental assistant II to monitor nitrous oxide during procedures is closely tied to the legal and regulatory guidelines governing the dental profession. A dental assistant II is typically permitted to monitor nitrous oxide administration only when a licensed dentist is present in the treatment room. This oversight ensures that a qualified professional is available to respond to any potential complications or emergencies that may arise during the administration of nitrous oxide, which is used for sedation and anxiety management in patients.

Monitoring nitrous oxide is not solely based on the type of procedure being performed or the specific training the assistant may have; rather, it fundamentally requires the presence of a dentist to maintain patient safety and uphold the standards of care in the dental practice. Therefore, the correct answer emphasizes the essential requirement of having a licensed dentist present when a dental assistant II is involved in monitoring nitrous oxide, ensuring adherence to established regulations and promoting patient safety.
