Self-contained systems for parenteral medication delivery are called?

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

Answer: (D)

Self-contained parenteral delivery systems are sterile, ready-to-use units that minimize handling in the field. A prefilled syringe fits this description perfectly: the medication is already drawn up in a sterile syringe, sealed, and ready for immediate administration. This setup preserves sterility, ensures accurate dosing, speeds delivery, and reduces the steps needed at the patient’s side—crucial advantages in emergency care. The other options aren’t about packaging or delivering a drug: recombinant DNA technology relates to producing biological products, while online and offline medical control refer to supervision and protocols, not the delivery system itself.
