A client with severe cardiogenic shock is receiving a continuous intravenous (IV) infusion of milrinone via a single 22-gauge22\text{-gauge} peripheral catheter. The client rapidly develops severe dyspnea, diffuse pulmonary crackles, and an oxygen saturation of 82%82\%. The healthcare provider prescribes a stat dose of IV bumetanide. Upon consulting the pharmacological reference, the nurse notes that bumetanide and milrinone are physically incompatible. Which of the following is the most appropriate nursing action?

  1. A
    Pause the continuous inotrope infusion, flush the line thoroughly with 0.9%0.9\% sodium chloride, administer the bumetanide, and restart the continuous infusion.
  2. Establish a second peripheral IV access site immediately to administer the stat dose of the loop diuretic.Cevap
  3. C
    Administer the bumetanide concurrently into the primary tubing at the Y-site closest to the insertion site to minimize medication contact time.
  4. D
    Withhold the stat diuretic dose and contact the healthcare provider to request an oral formulation due to the lack of compatible intravenous access.

Cevap

Establish a second peripheral IV access site immediately to administer the stat dose of the loop diuretic.
The client requires both medications urgently: milrinone to maintain cardiac output in cardiogenic shock, and bumetanide to treat acute pulmonary edema. Because the medications are physically incompatible, they cannot share an IV line. Furthermore, a life-sustaining inotropic infusion cannot be paused even momentarily without risking severe hemodynamic instability. Therefore, the nurse must immediately establish a second IV access site to safely administer the diuretic without compromising the inotropic support.

Adım Adım Çözüm

1
Analyze the client's current hemodynamic status and the nature of the primary infusion.
The client is in cardiogenic shock and relies on milrinone, a continuous life-sustaining inotrope, to maintain cardiac output.
Understanding the critical nature of the primary infusion dictates whether it can be safely interrupted.
2
Evaluate the IV compatibility of the newly prescribed stat medication.
Bumetanide is physically incompatible with milrinone.
Administering incompatible medications through the same IV line causes precipitation, posing severe embolic risks.
3
Determine the safest administration method that prioritizes both circulation (maintaining the inotrope) and breathing (administering the diuretic).
The nurse must immediately insert a new, secondary peripheral IV line.
The standard protocol of pausing and flushing an IV line for incompatible medications is contraindicated when the primary fluid is a life-sustaining vasoactive drip.
