Which practice helps prevent cross-contamination when using needles?

• A. Disposable needles
• B. Reusable
• C. Share between clients
• D. Reuse without sterilization

Answer: (A)

Using disposable needles is the best way to prevent cross-contamination. Each client gets a new sterile needle that’s opened just before use and then disposed of in a sharps container after the procedure. This means there’s no carryover of blood, tissue, or pathogens from one person to another, which is the core goal of infection-control measures.

Reusing needles or sharing them between clients, or reusing without proper sterilization, can transfer infectious material and expose clients to infections. Sterilization between uses is possible in theory, but it requires validated processes and strict controls; in practice, single-use disposable needles eliminate that risk entirely.
