Difficulty: MediumPharmacological and Parenteral Therapies

A registered nurse (RN) is caring for a critically ill client diagnosed with sepsis. The client's current vital signs include a blood pressure of 88/54 mmHg88/54\text{ mmHg}, heart rate of 112 beats/min112\text{ beats/min}, and a temperature of 38.9∘C38.9^\circ\text{C} (102∘F102^\circ\text{F}). The client is receiving a continuous intravenous (IV) infusion of dopamine through a single-lumen peripheral IV catheter to maintain hemodynamic stability. The healthcare provider prescribes a new intermittent IV piggyback of piperacillin-tazobactam. Which of the following actions by the nurse demonstrate safe pharmacological and parenteral practices? (Select all that apply.)

  1. Consult a drug reference guide or a clinical pharmacist to verify the Y-site compatibility of piperacillin-tazobactam and dopamine.Answer
  2. Assess the patency of the peripheral IV site and evaluate for signs of phlebitis or extravasation before initiating the antibiotic.Answer
  3. Calculate the piperacillin-tazobactam infusion rate in milliliters per hour (mL/hr) and administer the medication using an electronic infusion pump.Answer
  4. D
    Pause the continuous dopamine infusion for 60 minutes60\text{ minutes} to allow the piperacillin-tazobactam to infuse safely through the single-lumen catheter.
  5. E
    Connect the piperacillin-tazobactam secondary tubing directly to the primary IV line without checking compatibility, as antibiotics are universally compatible with vasopressors.
  6. F
    Delegate the pre-administration assessment of the client's vital signs and IV insertion site to an unlicensed assistive personnel (UAP).

Answer

The correct actions are to verify Y-site compatibility between the two medications, assess the IV insertion site for patency and potential complications, and utilize an electronic infusion pump for precise delivery of the antibiotic.
The correct actions prioritize client safety and adherence to strict pharmacological standards. Verifying Y-site compatibility prevents adverse drug reactions and dangerous precipitation in the IV line. Assessing the IV site ensures the vein is patent, which is crucial when administering vesicant or irritant medications. Utilizing an electronic infusion pump guarantees that the antibiotic is delivered at a precise and safe rate, minimizing the risk of infusion-related toxicity.

Step-by-Step Solution

1
Analyze the client's clinical condition and current therapies.
The client is hemodynamically unstable (hypotensive) and relies on a continuous dopamine infusion to maintain adequate circulation and perfusion.
Understanding the purpose of continuous vasoactive medications is essential to prioritize actions related to the ABCs (Airway, Breathing, Circulation).
2
Evaluate the safety principles required for administering a new IV piggyback medication.
The nurse must verify Y-site compatibility, thoroughly assess the insertion site, and calculate the correct pump rate in mL/hr.
These standard practices ensure that the newly prescribed medication does not precipitate with the primary infusion and is delivered safely into a functioning vein.
3
Identify contraindicated actions and improper delegation choices.
Pausing the life-sustaining dopamine infusion, assuming universal IV compatibility, and delegating nursing assessments to a UAP are identified as incorrect.
These actions directly compromise client safety, violate the nursing scope of practice, and ignore fundamental pharmacological and prioritization principles.

Key Concept

Safe administration of multiple IV medications requires verifying Y-site compatibility, utilizing infusion pumps for precise delivery, and maintaining continuous life-sustaining infusions without dangerous interruptions.
