HESI General Chairside Assisting Practice Exam

Which item is classified as non-consumable in a dental office?

1. Disposable syringes

2. High-speed handpiece

3. Dental masks

4. Exam gloves

The correct answer is: High-speed handpiece

The high-speed handpiece is classified as non-consumable in a dental office because it is a durable instrument designed for repeated use over an extended period. Unlike consumable items that are used once and then discarded, the high-speed handpiece is maintained and sterilized after each use, allowing it to function effectively for many procedures. In contrast, items such as disposable syringes, dental masks, and exam gloves are all designed for single use. They are intended to be used once during patient care and then discarded to prevent cross-contamination and maintain infection control protocols in the dental practice. This distinction helps ensure that the dental environment remains safe and hygienic for both patients and dental professionals.
