Zorluk: OrtaPharmacological and Parenteral Therapies

Following a severe myocardial infarction, a client requires pharmacological blood pressure support. The client is currently receiving a continuous dopamine infusion at 5 mcg/kg/min through their only patent peripheral venous access site, maintaining a mean arterial pressure (MAP) of 68 mm Hg. The healthcare provider prescribes a scheduled dose of an intermittent intravenous antibiotic. Upon consulting the facility's parenteral drug reference, the nurse confirms the antibiotic is completely incompatible with dopamine. What is the most appropriate intervention for this situation?

  1. A
    Halt the vasoactive medication temporarily until the intermittent infusion is complete.
  2. B
    Piggyback the new medication at the injection port closest to the client's insertion site.
  3. Insert an additional venous catheter to deliver the scheduled antibiotic dose.Cevap
  4. D
    Administer a sterile saline flush to clear the line before delivering the secondary medication.

Cevap

The most appropriate intervention is to insert an additional venous catheter to deliver the scheduled antibiotic dose.
Dopamine is a short-acting vasoactive medication critical for maintaining the client's blood pressure and cardiac output. It must infuse continuously without interruption to prevent acute hemodynamic collapse. Because the newly prescribed antibiotic is incompatible with dopamine, it cannot be administered through the same intravenous line. Therefore, initiating a separate access site is the only safe method to ensure both medications are delivered effectively.

Adım Adım Çözüm

1
Identify the nature of the primary continuous infusion.
The client is receiving dopamine, a critical vasoactive medication with a very short half-life used to maintain blood pressure.
To determine if the primary infusion can be safely interrupted for secondary drug administration.
2
Analyze the drug compatibility constraints.
The new antibiotic is completely incompatible with dopamine at the Y-site.
To verify whether the two medications can share the same intravenous pathway.
3
Formulate a safe administration plan.
A separate intravenous site must be initiated because the dopamine cannot be stopped and the drugs cannot mix.
To maintain the client's hemodynamic stability while safely delivering the prescribed antibiotic therapy.
