Difficulty: EasyPharmacological and Parenteral Therapies

A nurse is preparing to administer a prescribed intravenous (IV) piggyback medication to a client who is currently receiving a continuous IV infusion of 0.9% sodium chloride. What is the priority nursing action before attaching the secondary IV tubing to the primary line?

  1. A
    Delegate the assembly of the IV piggyback tubing and priming process to an unlicensed assistive personnel (UAP).
  2. Verify the compatibility of the piggyback medication with the continuous IV fluid.Answer
  3. C
    Add the secondary infusion volume to the primary infusion volume to calculate a combined continuous drip rate.
  4. D
    Assume the piggyback medication is compatible with the continuous fluid unless a pharmacy warning label is present.

Answer

The correct action is to verify the compatibility of the piggyback medication with the primary IV fluid.
Before administering any secondary intravenous medication (piggyback) into an existing continuous IV line, it is a critical safety standard to verify that the two fluids are compatible. Administering incompatible fluids together can cause chemical reactions, rendering the medication ineffective, or creating solid precipitates that can cause fatal embolisms.

Step-by-Step Solution

1
Identify the clinical scenario
The nurse is preparing to administer an IV piggyback medication into an existing, running continuous IV line.
Understanding the context is required to determine the necessary safety steps before administration.
2
Recall the principles of safe parenteral medication administration
Medications administered via the same IV line must be physically and chemically compatible to prevent adverse reactions like precipitation.
Mixing incompatible medications can cause crystal formation, which can lead to catheter occlusion or dangerous emboli in the client.
3
Evaluate the provided options against priority safety actions
Checking IV compatibility is the essential priority safety action. Delegating to UAP is out of scope, combining rates is mathematically incorrect, and assuming compatibility based on missing warning labels is dangerous.
Ensuring medication compatibility directly addresses the highest physiological risk to the client in this specific scenario.
