Which term describes prefixed syringes with attached needles for quick use?

• A. Ampules
• B. Vials
• C. Self-Contained Systems
• D. Single-Dose Vials

Answer: (C)

Prefilled syringes with attached needles are designed to be used immediately without any preparation. The term that describes these is self-contained systems. They come as a single, sealed unit containing the medication, a syringe, and a needle already attached, ensuring sterility and speed—ideal for emergency or prehospital scenarios where every second counts. You don’t need to assemble or draw up from a vial or ampule, which reduces contamination risk and dosing errors and makes administration faster. Ampules require breaking open and transferring the drug into a syringe, adding steps and potential exposure. Vials require drawing up the medication into a syringe and typically attaching a needle, adding steps and contamination risk. Single-dose vials are still vials to be accessed with a syringe and are not a preassembled package.
