Which best describes how IV piggyback infusions are typically scheduled?

• A. Administered with no specific scheduling
• B. Given as a continuous infusion without interruption
• C. Delivered as a rapid push bolus
• D. Administered as a small-volume infusion over 15–60 minutes

Answer: (D)

IV piggyback infusions are short, intermittent medications given through a secondary IV line and connected to the primary line. They are scheduled to run over a defined, brief period—typically 15 to 60 minutes—so the medication is administered in a controlled time frame. This differs from a continuous infusion (which runs nonstop) and from a rapid push bolus (which is delivered very quickly in a single, hastened attempt). The small-volume, time-defined nature of IVPBs allows the drug to be given efficiently while the primary IV remains in use, and the dose timing is set per the order rather than left unscheduled.
