Which of the following is true about the duties of the RDA?

The correct answer highlights the requirement for Registered Dental Assistants (RDAs) to work under direct supervision for specific tasks. In California, RDAs are permitted to perform a variety of clinical and administrative duties to support the dentist. However, certain procedures require direct supervision, which means that a licensed dentist must be physically present in the treatment facility.

This rule ensures that the quality of care and patient safety are maintained, as some tasks carry higher risks or complexities that necessitate a dentist's oversight. For instance, tasks requiring anesthesia or those that may significantly impact a patient's oral health are reserved for a dentist to control and direct the procedure.

The other options are based on misunderstandings of the scope of practice for RDAs. The assertion that RDAs can perform any procedure without supervision is misleading, as certain procedures are strictly governed by regulations that outline the level of supervision required. Additionally, while some tasks can be performed without the dentist's inspection afterward, removing sutures usually falls under tasks that necessitate either supervision or inspection. Therefore, understanding the regulations governing RDAs is crucial for ensuring compliance and protecting patient safety.
