Which porous items must be discarded after client use, based on typical examples?

• A. Neck strip
• B. Sponge
• C. Emery board
• D. All of the above

Answer: (D)

Porous items that touch a client must be discarded after each use because their material can trap moisture, oils, and microbes that aren’t fully removed by cleaning. Neck strips are meant for single-client use and should be disposed of to prevent skin irritation and infection. Sponges absorb liquids and harbor bacteria in their pores, so they’re typically single-use or discarded after each client. Emery boards are porous and cannot be reliably sterilized between clients, making reuse a cross-contamination risk. Since every listed item fits this safety rule, the correct choice is all of the above.
