DANB General Chairside Practice Test

When using the single-handed technique to transfer an instrument, where should the dental assistant position the working end of the instrument?

1. Toward the assistant

2. Toward the patient

3. Toward the operator

4. Toward the overhead light

The correct answer is: Toward the operator

In the single-handed technique for transferring instruments, the dental assistant positions the working end of the instrument toward the operator, typically the dentist. This is crucial because it allows for a smooth and efficient transfer during dental procedures. By positioning the working end toward the operator, the assistant ensures that the dentist can immediately grasp the instrument without having to adjust or reposition it, thereby maintaining the flow of the procedure and minimizing the risk of dropping the instrument. This technique also promotes safety and efficiency in the dental operatory. If the working end were directed toward the patient or the assistant, it could lead to potential safety hazards, such as accidentally injuring the patient or causing the assistant to fumble with the instrument. Directing the working end toward the overhead light would not be practical either, as it does not facilitate the dentist's use of the instrument. Overall, this method emphasizes effective communication and coordination between the dental assistant and the operator, enhancing the overall patient care experience.
