Difficulty: EasyPharmacological and Parenteral Therapies

While caring for a hospitalized client, the nurse prepares to hang a scheduled intravenous (IV) antibiotic. The client already has a continuous IV drip of a different medication infusing through a single-lumen peripheral venous catheter. What is the most critical action the nurse must take before connecting the antibiotic to the Y-site?

  1. Check a pharmacological reference to confirm the two medications are compatible.Answer
  2. B
    Flush the primary IV tubing with 10 mL of sterile 0.9% sodium chloride.
  3. C
    Stop the continuous drip entirely while the antibiotic infusion completes.
  4. D
    Request a prescription to establish a second peripheral IV access site.

Answer

Check a pharmacological reference to confirm the two medications are compatible.
Before administering multiple intravenous medications concurrently through the same access point, it is a fundamental safety standard to consult a reliable drug reference to verify physical and chemical compatibility. Administering incompatible medications can result in precipitation, which can occlude the catheter or cause a life-threatening embolus in the client.

Step-by-Step Solution

1
Identify that two distinct medications are planned to infuse through the same single-lumen intravenous line.
Recognize the potential for the medications to mix at the Y-site and within the client's vein.
Mixing unknown medications poses a significant safety risk.
2
Prioritize client safety by determining the chemical and physical properties of the drug combination.
Consult an approved facility drug reference guide or pharmacist.
Compatibility must be established prior to administration to prevent precipitation, crystallization, or drug inactivation.
