What is the difference between IV push and IV piggyback administration?

• A. IV push is a rapid bolus injected over a few seconds; IV piggyback is a small-volume infusion given over 15–60 minutes
• B. IV push is a slow drip; IV piggyback is a large-volume infusion
• C. IV push is a continuous infusion; IV piggyback is a bolus
• D. IV push is a rapid bolus given over several minutes; IV piggyback is a bolus

Answer: (D)

The main idea tested is how the rate and setup differ between IV push and IV piggyback. IV push is a rapid bolus injected directly into the IV line over a short period, typically a minute or two (or even seconds for some drugs). IV piggyback uses a secondary, small-volume bag and is infused over a longer, controlled window, usually 15 to 60 minutes, sometimes longer depending on the medication. The piggyback setup means the drug is given as an intermittent infusion rather than a single rapid injection. So, IV push = fast, direct injection; IV piggyback = slower, timed infusion through a secondary line.
