Zorluk: ZorPharmacological and Parenteral Therapies

A client with severe decompensated heart failure is admitted to the intensive care unit with a double-lumen peripherally inserted central catheter (PICC) in place. Lumen 1 is infusing continuous dobutamine, and Lumen 2 is infusing continuous 0.9%0.9\% sodium chloride. The healthcare provider prescribes stat intravenous (IV) furosemide, a continuous IV heparin infusion, and a scheduled dose of IV potassium chloride. Which actions by the nurse are appropriate? Select all that apply.

  1. Administer the stat IV furosemide through Lumen 2 after flushing the port with 0.9%0.9\% sodium chloride.Cevap
  2. B
    Temporarily pause the continuous dobutamine infusion to administer the stat IV furosemide through Lumen 1.
  3. Verify the physical compatibility of the continuous heparin infusion with 0.9%0.9\% sodium chloride before connecting it to Lumen 2.Cevap
  4. D
    Set the infusion pump to deliver the IV potassium chloride at a rate of 40 mEq/hr40\text{ mEq/hr} to ensure rapid therapeutic effect.
  5. E
    Connect the continuous heparin infusion to the Y-site of the dobutamine infusion to reserve the other lumen for intermittent medications.
  6. Evaluate the client's continuous electrocardiogram (ECG) rhythm and baseline serum creatinine prior to initiating the potassium chloride.Cevap

Cevap

The nurse should administer the furosemide through Lumen 2 after flushing, verify the compatibility of heparin with the normal saline in Lumen 2, and evaluate the ECG rhythm and renal function before giving the potassium chloride.
Safe central line management and pharmacology principles require the nurse to protect dedicated lines for vasoactive infusions, thoroughly verify fluid compatibility before Y-site administration, flush lines adequately between intermittent medications, and apply rigorous monitoring and rate limits to high-alert electrolytes like potassium chloride.

Adım Adım Çözüm

1
Analyze the critical nature of the existing infusions.
Identify that dobutamine (Lumen 1) is a life-sustaining vasoactive medication that cannot be paused or interrupted.
Maintaining hemodynamic stability is the highest priority in decompensated heart failure.
2
Evaluate compatibility constraints for the new prescriptions.
Determine that heparin and dobutamine are incompatible, so heparin cannot be infused via Lumen 1.
Mixing incompatible medications causes precipitation, risking embolism and altered drug efficacy.
3
Plan safe administration parameters for high-alert medications.
Recognize that IV potassium chloride requires strict rate limits (max 20 mEq/hr20\text{ mEq/hr} centrally) and pre-assessment of renal and cardiac status.
Rapid or unmonitored potassium administration can cause fatal cardiac arrhythmias.

Anahtar Kavram

Safe administration of parenteral therapies requires continuous maintenance of critical inotropes, strict verification of IV compatibility, and adherence to high-alert medication administration parameters.
