HESI General Chairside Assisting Practice Exam

When passing a hinged instrument, where does the chairside assistant grasp the instrument?

1. At the handle

2. Near the tip

3. At the neck

4. At the hinges

The correct answer is: At the hinges

When passing a hinged instrument, the correct practice involves grasping the instrument at the hinges. This method provides better control and stability for both the assistant and the dentist. By holding the instrument at the hinges, the assistant ensures that the handling does not interfere with the functionality of the instrument, as this area is typically easier to stabilize during use. Grasping the instrument at the hinges also minimizes the risk of the instrument accidentally closing on the patient's tissue or the assistant’s hand, which could lead to injury. This technique allows the dentist to immediately access the instrument while maintaining an optimal grip, enabling quick and efficient exchange of instruments during a procedure. Holding the instrument at other points, such as the handle or near the tip, could compromise the instrument's function and potentially create hazards. Therefore, understanding the correct method ensures safety and efficiency in the dental practice.
