Where should an IV piggyback medication be hung relative to the existing IV infusion?

• A. Lower than the existing bag
• B. At the same level as the existing bag
• C. Higher than the existing bag
• D. Not connected to the same IV site

Answer: (C)

When delivering a secondary IV piggyback, the medicated bag should be hung higher than the primary IV bag. This height difference uses gravity to push the piggyback solution into the IV line first and prevents backflow from the primary infusion into the secondary line. If the piggyback were at the same level or lower, fluid from the primary could back up into the piggyback line or flow unpredictably, risking improper dosing or contamination. Keeping the piggyback higher ensures a one-way, controlled flow into the bloodstream through the secondary line.
