A delivery device that provides ready-to-use, single-dose injections for immediate administration is known as?

• A. Recombinant DNA technology
• B. USP
• C. Prefilled syringes
• D. On-line medical control

Answer: (C)

Prefilled syringes are the delivery device that provides ready-to-use, single-dose injections for immediate administration. They arrive with the exact dose already prepared, so there’s no need to draw up medication from a vial, which saves time and reduces the chance of dosing or contamination errors in fast-paced situations. This is particularly important in emergency and prehospital care, where rapid, reliable delivery of medications can be critical. The other terms describe concepts that aren’t delivery devices: recombinant DNA technology is a lab technique for genetic manipulation; USP refers to a standards organization for drug quality; online medical control is remote physician guidance, not a physical drug delivery device.
