Answer:
The correct answer is "a supervision duty for a RDA".
Explanation:
According to the California Dental Practice Act, RDA establishes all the duties that a dental assistant is able to perform. These duties are limited, since they do not have the background and abilities that a dentist have during his career. However, a dental assistant could still perform many duties, including: mouthmirror inspection of the oral cavity and charting of obvious lesions.
