A nurse is preparing to administer a prescribed intravenous (IV) infusion of potassium chloride to a client who has a serum potassium level of 2.9 mEq/L and is experiencing premature ventricular contractions (PVCs). Which actions are safe and appropriate for the nurse to implement? Select all that apply.

  1. Ensure the potassium chloride solution is administered using an electronic infusion pump.Cevap
  2. Verify that the client has a urine output of at least 30 mL/hr before initiating the infusion.Cevap
  3. Set the peripheral IV infusion rate to deliver a maximum of 10 mEq of potassium per hour.Cevap
  4. D
    Program the IV pump drip rate to infuse the entire potassium dose over 15 minutes to quickly resolve the arrhythmias.
  5. E
    Administer the potassium solution concurrently with other intravenous medications without verifying Y-site compatibility.

Cevap

The safe and appropriate actions are to administer the solution using an electronic infusion pump, verify adequate urine output prior to the infusion, and limit the peripheral infusion rate to a maximum of 10 mEq per hour.
Intravenous potassium chloride is a high-alert medication. Safe administration requires using an electronic infusion pump to prevent accidental boluses. Because potassium is excreted by the kidneys, the nurse must verify adequate urine output (at least 30 mL/hr) prior to administration to prevent hyperkalemia. Additionally, to avoid cardiac toxicity and severe vein irritation, the infusion rate through a peripheral line should never exceed 10 mEq per hour.

Adım Adım Çözüm

1
Analyze the prescribed medication and the client's clinical presentation.
The client has severe hypokalemia (2.9 mEq/L) with cardiac manifestations (PVCs) and requires intravenous potassium chloride, which is a high-alert medication.
Identifying high-alert medications is critical for determining the required safety protocols for administration.
2
Evaluate the safe administration parameters for intravenous potassium chloride.
Safe parameters include always using an infusion pump, ensuring a maximum peripheral rate of 10 mEq/hr, and confirming renal function (urine output >30 mL/hr).
Adhering to strict administration parameters prevents fatal arrhythmias and hyperkalemia.
3
Identify and reject unsafe practices from the available options.
Rapid infusion rates and failing to check IV compatibility are identified as severe safety risks and are rejected.
Potassium given too quickly directly causes cardiac arrest, and incompatible IV medications can cause dangerous precipitation in the line.
