All single-use items must be:

• A. Reused after sterilizing
• B. Repaired and reused
• C. Discarded after use
• D. Returned to supplier

Answer: (C)

Single-use items are meant for one client and one procedure only. After they’ve touched hair or skin, their surfaces can harbor microbes and their integrity can be compromised, making safe reuse unreliable even if you try sterilizing them. Reusing after sterilizing isn’t appropriate because sterilization can’t always restore safety for items that have already been contaminated or damaged. Repairing and reusing isn’t a safe option for disposable items, since they aren’t designed to be brought back to a sterile state. Returning used items to a supplier isn’t how safety procedures work in practice—proper disposal is the standard. For these reasons, they’re discarded after use to prevent cross-contamination and protect clients.
