The nurse is preparing to administer a prescribed antibiotic via IV piggyback to a client with a stable, existing peripheral IV line. Which action is essential before starting the infusion?
- Flush the IV line with 10 mL of heparin.
- Check for compatibility between the antibiotic and the primary IV fluid. (correct answer)
- Ask the RN to start a new IV line for the antibiotic.
- Set the primary bag to a keep-vein-open (KVO) rate.
Explanation: Before administering an IV piggyback medication, it is critical to verify the compatibility of the secondary medication with the primary IV solution. If the solutions are incompatible, a precipitate could form, clogging the IV line and potentially causing an embolus. This is a crucial safety check. Flushing with heparin is not standard for peripheral IVs, and a new line is unnecessary if the current one is patent and the fluids are compatible.
