Registered Dental Hygienist in Alternative Practice (RDHAP) Law and Ethics Practice Exam

Which items are classified as semi-critical?

1. Instruments that penetrate soft tissue

2. Devices that contact oral mucous membranes

3. Items used in cleaning

4. Instruments that contact only intact skin

The correct answer is: Devices that contact oral mucous membranes

Semi-critical items are defined as those that come into contact with oral mucous membranes. This classification is essential in infection control protocols, particularly in dental hygiene practice, as these items warrant a high level of disinfection or sterilization to prevent the potential transmission of infections. In this context, the correct answer highlights that devices interacting with oral mucous membranes have a higher risk of harboring pathogens compared to items that only contact intact skin or are involved in cleaning. It is important to differentiate between these categories, as each requires varying levels of disinfection based on the type of contact they have with human tissue. Items that penetrate soft tissue are classified as critical and require sterilization, while instruments that contact only intact skin are considered non-critical and can be cleaned with lower-level disinfection. Understanding these classifications is crucial for maintaining proper hygiene standards and ensuring patient safety during dental procedures.
