Which statement correctly describes a locking syringe tip?

• A. Has a threaded outer collar sized to accept the needle hub
• B. Plain tips are friction-fit inside the hub
• C. Locking tips are friction-fit
• D. Neither uses threading

Answer: (A)

Locking syringe tips attach by a threaded connection. The outer collar on the tip is threaded so a needle hub screws on, creating a secure, locked fit that resists coming loose during use. That’s exactly what the statement describes. Plain tips, by contrast, rely on friction to hold the hub and do not use threading, so they are not describing the locking mechanism. Because locking tips use threading to lock the needle in place, the other options don’t describe how a locking tip works.
