A nurse is caring for a client who is receiving a continuous infusion of Total Parenteral Nutrition (TPN) through a dedicated single-lumen peripherally inserted central catheter (PICC). The healthcare provider prescribes a stat dose of intravenous ceftriaxone to treat a newly diagnosed infection. The client currently has no other intravenous access. Which of the following actions should the nurse take?

  1. Insert a new peripheral intravenous catheter to administer the ceftriaxone.Cevap
  2. B
    Pause the Total Parenteral Nutrition infusion, flush the catheter with normal saline, infuse the ceftriaxone, and then resume the nutrition.
  3. C
    Attach the ceftriaxone tubing to the lowest port on the Total Parenteral Nutrition line and infuse both solutions simultaneously.
  4. D
    Wait until the current bag of Total Parenteral Nutrition is completely infused before administering the ceftriaxone.

Cevap

The nurse must insert a new peripheral intravenous catheter to administer the ceftriaxone because the Total Parenteral Nutrition (TPN) line must remain strictly dedicated.
Total Parenteral Nutrition (TPN) is a complex, hypertonic solution that must be administered through a dedicated central line lumen. This protocol prevents dangerous drug incompatibilities (such as calcium in the TPN precipitating with ceftriaxone) and minimizes the risk of central line-associated bloodstream infections (CLABSI). Because the client only has a single-lumen central catheter, the nurse must establish new peripheral intravenous access to administer the urgent antibiotic safely and effectively without disrupting the TPN.

Adım Adım Çözüm

1
Analyze the client's current intravenous access and infusions.
The client has a single-lumen PICC dedicated solely to a continuous TPN infusion, and a stat dose of an intravenous antibiotic is required.
Understanding the current access limitations is necessary to determine the safest route for new medications.
2
Evaluate the compatibility and protocols regarding TPN administration.
TPN requires a strict, dedicated line. It cannot be paused abruptly without risking rebound hypoglycemia, and it cannot be mixed with medications like ceftriaxone due to severe incompatibility issues (e.g., calcium precipitation).
Applying pharmacological safety principles prevents life-threatening adverse events like emboli or severe hypoglycemic episodes.
3
Determine the most appropriate nursing intervention to safely administer the prescribed medication.
The nurse must obtain a new access site by inserting a peripheral intravenous catheter to give the stat antibiotic promptly.
This ensures the client receives timely treatment for the infection while maintaining the integrity and safety of the TPN infusion.

Anahtar Kavram

Total Parenteral Nutrition requires a strictly dedicated intravenous line and must never be abruptly paused or mixed with other medications.
