In proper syringe assembly, which step is the second?

• A. Place carpule into the syringe.
• B. Place needle onto the syringe.
• C. Place the recapping card onto the needle.
• D. Engage the harpoon & pull back to check engagement.

Answer: (B)

Mounting the needle is the next essential move after loading the cartridge because the syringe isn’t a complete, usable unit until the needle is attached. With the carpule in place, you need a sterile needle to provide the pathway for delivery and to allow you to perform aspiration checks and subsequent use safely. Attempting to verify harpoon engagement or draw back without a needle attached isn’t feasible and wouldn’t reflect actual use, since fluid movement is through the needle. After the needle is on, you can proceed with confirming the harpoon engagement and then finish with safety steps like recapping as appropriate.
