In PMU practice, which type of instrument requires sterilization due to entering sterile tissue or the vascular system?

• A. Critical instruments that enter sterile tissue or the vascular system.
• B. Non-critical surfaces.
• C. Single-use items only.
• D. Tools used for client communication.

Answer: (A)

Infection-control levels categorize instruments by risk to sterile sites. Instruments that enter sterile tissue or the vascular system are considered critical because they have direct access to areas that must remain sterile. These items must be sterilized between clients (or be used as unopened, single-use disposables) to prevent transmitting infection or disease. In PMU practice, needles, blades, and any device that penetrates skin or mucosa fall into this category and require sterilization. Non-critical surfaces only contact intact skin, so they’re cleaned and disinfected rather than sterilized. Single-use items are designed to be disposed of after one client and aren’t sterilized for reuse. Tools used for client communication don’t contact sterile tissue and aren’t treated as critical items for sterilization purposes.
