Zorluk: OrtaPharmacological and Parenteral Therapies

A client with severe Crohn's disease is receiving a continuous infusion of total parenteral nutrition (TPN) through a single-lumen peripherally inserted central catheter (PICC). The healthcare provider prescribes intermittent intravenous (IV) ceftriaxone 1 g1\text{ g} every 12 hours12\text{ hours}. Which action represents the safest practice for administering this antibiotic?

  1. Initiate a separate peripheral IV access site to administer the antibiotic.Cevap
  2. B
    Connect the antibiotic as a secondary piggyback to the Y-site of the continuous infusion.
  3. C
    Pause the continuous nutrition infusion, flush the line with normal saline, administer the antibiotic, and resume the nutrition.
  4. D
    Add the prescribed dose of the antibiotic directly into the total parenteral nutrition bag.

Cevap

The nurse should initiate a separate peripheral IV access site to administer the antibiotic.
Total parenteral nutrition (TPN) contains a complex mixture of amino acids, dextrose, lipids, vitamins, and minerals. Because of its hypertonicity and high glucose content, TPN must run through a dedicated central line to prevent severe complications such as drug-drug incompatibilities, microvascular precipitates, and central line-associated bloodstream infections (CLABSI). The safest and most appropriate nursing action is to start a new, separate peripheral IV line exclusively for the administration of the prescribed antibiotic.

Adım Adım Çözüm

1
Identify the primary therapy currently being administered to the client.
The client is receiving total parenteral nutrition (TPN) via a single-lumen PICC.
Understanding the current infusion is critical for determining compatibility and line access requirements.
2
Recall the standard safety principles for administering TPN.
TPN must always be administered through a dedicated line. Other medications or fluids should not be mixed or Y-sited with TPN.
TPN solutions are complex mixtures with a high risk of precipitation when mixed with other drugs, and the high glucose content increases the risk of central line infections if the system is frequently accessed.
3
Determine the most appropriate method to administer the newly prescribed IV antibiotic.
Since the only current access is a single-lumen dedicated TPN line, a new separate peripheral IV access must be established.
This ensures the client receives the necessary antibiotic safely without compromising the TPN infusion or risking incompatibility.
