Which procedure should a dental nurse never perform?

Administering sedation without supervision is a procedure that a dental nurse should never perform because it involves significant risks and requires a high level of specialized training and competence. Sedation involves the use of medications that can depress the central nervous system, potentially leading to complications such as respiratory issues or adverse reactions. Because of these risks, the administration of sedation must be overseen by qualified dental professionals who have the appropriate skills and knowledge to manage any potential emergencies that may arise.

In contrast, assisting during surgery, taking patient history, and handing instruments to the dentist are appropriate tasks for dental nurses that fall within their training and scope of practice. These tasks support the overall workflow of dental procedures while ensuring patient care and safety under the supervision of a licensed dentist.
