What is required for N2O to be administered in a dental practice?

The correct response highlights an essential safety and compliance requirement for the administration of nitrous oxide (N2O) in a dental practice. According to regulations and best practices, the presence of both the dentist and at least one other qualified auxiliary personnel is necessary to ensure that N2O is administered safely and effectively.

This requirement ensures that there is adequate supervision during the procedure and that a trained individual is available to monitor the patient’s vital signs and overall condition, thereby minimizing risks associated with the use of nitrous oxide. The dentist is responsible for the patient’s care and has the expertise to manage any complications that may arise while the auxiliary can assist in managing the administration, maintaining equipment, and monitoring the patient's response.

Other options do not meet the necessary safety protocols or legal requirements. For instance, the choice stating only the dentist must be present does not take into account the need for immediate support that a trained auxiliary can provide. The option that allows any trained staff to administer N2O does not restrict this authority to only those adequately trained and vetted by regulatory bodies. Finally, while consent is important in any medical procedure, it does not address the necessity for a collaborative presence of qualified professionals during the administration of N2O.
