Under what circumstances should nail and foot spa tools be sterilized?

• A. To eliminate spores and bacteria; typically for reusable implements that penetrate the skin or come into contact with broken skin
• B. To prevent rust on tools
• C. To remove nail polish residue
• D. To comply with product labeling

Answer: (B)

Sterilization is about killing all microorganisms, including spores, on tools that will contact or penetrate the skin. When a reusable implement goes through or touches broken skin, it must be sterilized to prevent cross-contamination and infection. This isn’t about keeping tools from rusting or about removing nail polish or following product labels—that’s cleaning, maintenance, or labeling concerns. So the instance that calls for sterilization is when tools will penetrate skin or contact broken skin, to ensure complete microbial elimination.
