Which of the following items should NOT be reused between clients?

• A. Metal tools
• B. Disposable files
• C. Glass cuticle pushers
• D. None of the above

Answer: (B)

The correct answer is that disposable files should not be reused between clients. Disposable files are designed for single-use only due to their inability to be effectively sanitized or disinfected after use. Once used on a client's nails, they may harbor bacteria, fungi, or other pathogens that could be transferred to the next client, posing a health risk.

On the contrary, metal tools and glass cuticle pushers can be reused between clients as long as they are properly sterilized and disinfected in accordance with state board regulations. Metal tools can withstand high temperatures and can be effectively sterilized using autoclaves, while glass cuticle pushers can be cleaned and disinfected without damage. Therefore, understanding the importance of single-use versus reusable items is crucial for maintaining a safe and hygienic salon environment.
