Difficulty: MediumAccident, Error, and Injury Prevention

A registered nurse is providing care for a client who is receiving a continuous intravenous (IV) heparin infusion to treat a deep vein thrombosis. The healthcare provider prescribes a scheduled dose of IV vancomycin. The client currently has a single peripheral IV access site. Which action by the nurse is essential to ensure client safety and prevent a medical error?

  1. Consult a reliable drug reference database to confirm the physical compatibility of vancomycin and heparin.Answer
  2. B
    Administer the vancomycin directly into the primary heparin line's Y-site to prevent the pain of an additional venipuncture.
  3. C
    Instruct an unlicensed assistive personnel (UAP) to assess the IV site frequently for signs of redness or infiltration.
  4. D
    Apply a soft bilateral wrist restraint to ensure the client does not accidentally dislodge the critical IV line.

Answer

The nurse must consult an approved drug reference database to verify the compatibility of the two intravenous medications before administration.
The correct action demonstrates fundamental medication safety principles. Before any two intravenous medications share the same tubing, the nurse is strictly required to check a drug reference database for compatibility. Heparin and vancomycin are a well-known example of drugs that often require separate lines due to physical incompatibility.

Step-by-Step Solution

1
Identify the clinical situation and the prescribed interventions.
The client is receiving a continuous high-alert infusion (heparin) and needs another IV medication (vancomycin) through the same single access site.
Understanding the existing setup is required to determine the risk of drug interactions or line complications.
2
Determine the safety requirements for co-administering IV medications.
Medications cannot be mixed in the same IV line unless they are proven to be physically and chemically compatible.
Incompatible medications can cause precipitation, leading to loss of drug efficacy or dangerous emboli.
3
Select the safest nursing intervention to prevent an error.
The nurse must verify compatibility using a reliable drug reference before proceeding with the administration.
This action directly prevents a potential adverse drug event and ensures client safety.
