A nurse is preparing to administer a scheduled dose of intravenous pantoprazole to a client. The client is currently receiving a continuous infusion of total parenteral nutrition (TPN) through a single-lumen peripherally inserted central catheter (PICC). Which of the following is the most appropriate action by the nurse?

  1. A
    Stop the nutritional infusion, flush the line with normal saline, administer the medication, and flush again.
  2. Establish a new peripheral intravenous catheter to administer the medication.Answer
  3. C
    Connect the medication secondary tubing to the lowest Y-site port on the primary nutritional infusion tubing.
  4. D
    Withhold the medication until the nutritional infusion is complete and document the reason for the delay.

Answer

Establish a new peripheral intravenous catheter to administer the medication.
Total Parenteral Nutrition (TPN) solutions have high glucose and amino acid concentrations, making them highly prone to bacterial growth and chemical incompatibilities. Evidence-based nursing practice dictates that TPN must be administered through a dedicated central line lumen. No other medications, intravenous fluids, or blood products should be administered through this specific lumen. Because the client currently has only a single-lumen PICC which is actively in use for the TPN, the nurse must establish a new peripheral intravenous site to administer the scheduled pantoprazole safely.

Step-by-Step Solution

1
Identify the client's current intravenous access and ongoing infusions.
The client has a single-lumen PICC that is actively being used for a continuous TPN infusion.
Evaluating current vascular access is required before safely administering any new intravenous medication.
2
Recall the safety administration principles for Total Parenteral Nutrition.
TPN solutions require a dedicated central venous line or lumen; no other fluids or medications can share this access.
TPN has a high osmolarity, high glucose content, and specific pH that increases the risk of infection, chemical incompatibility, and precipitate formation when mixed with other drugs.
3
Determine the safest method to administer the prescribed pantoprazole.
Since the sole central line lumen is dedicated to TPN, a new peripheral IV catheter must be inserted.
Providing alternative venous access ensures the client receives the scheduled medication without compromising the safety of the TPN infusion.
