California Registered Dental Assistant (RDA) Written Practice Exam

Besides the assistant, what else would be located in the assistant's zone?

1. Patient records

2. Dental unit and assistant's stool

3. Sterilization equipment

4. Extraoral imaging systems

The correct answer is: Dental unit and assistant's stool

In the assistant's zone, you would typically find the dental unit and the assistant's stool, as these are essential tools for the assistant to perform their duties. Options A, C, and D are located in other areas of the dental office and are not typically found in the assistant's zone. Patient records are usually kept in a designated area for privacy and confidentiality. Sterilization equipment is typically located in a separate designated area to ensure proper sterilization and infection control. Extraoral imaging systems are usually located in the radiography or x-ray room. Therefore, option B is the most accurate answer for what would be located in the assistant's zone.
