Under general supervision, what task can Bill, a registered dental assistant (RDA), perform?

Under general supervision, a registered dental assistant (RDA) has specific tasks they are allowed to perform based on California dental law. Therefore, the task of placing and removing temporary sedative dressings aligns with the duties permitted under general supervision. This function is considered supportive and assists in the patient care process, which is appropriate under supervision guidelines.

The role of an RDA, while versatile, includes specific limitations regarding procedures that require more direct oversight or professional judgment. For instance, the application of etchant is typically a task that requires closer supervision due to the materials involved and the need for careful application. The administration of nitrous oxide is a more advanced procedure generally restricted to licensed professionals like dentists or dental hygienists due to the safety implications associated with sedative gases. Lastly, prescribing medications is a responsibility that lies solely with licensed dentists or physicians, as it requires a comprehensive understanding of pharmacology and patient care that falls outside the RDA’s scope.

Thus, placing and removing temporary sedative dressings falls within the duties that an RDA can perform under general supervision, making it the correct choice in this context.
