Puncture tools must be sterilized to prevent infection.

• A. True
• B. False
• C. Only if they touch mucous membranes
• D. Only if not used for 24 hours

Answer: (A)

Sterilizing puncture tools is essential because these instruments pierce skin and can carry microorganisms that cause infection if any remain. Sterilization eliminates all microbial life, including spores, giving the highest level of safety between clients. So, true is the correct choice: these tools should be sterilized between uses or disposed of if single-use. Relying on cleaning or disinfection alone isn’t enough, since they don’t guarantee complete elimination of all pathogens.
