A nurse is caring for a client who is receiving a continuous transfusion of packed red blood cells (PRBCs) through a primary peripheral intravenous (IV) catheter. The client's latest laboratory results reveal a critically low serum potassium level of 2.3 mEq/L, and the healthcare provider prescribes a dose of 40 mEq of IV potassium chloride. A second, saline-locked peripheral IV access is available on the client's other arm. Which of the following is the safest nursing action to implement?
- AAdminister the potassium chloride as a slow, direct IV push into the saline-locked access over a minimum of 5 to 10 minutes.
- BAttach the potassium chloride as a secondary piggyback infusion to the IV line currently administering the packed red blood cells.
- Connect a pre-mixed potassium chloride infusion to the saline-locked IV access and administer it via an electronic pump at a maximum rate of 10 mEq per hour.Cevap
- DInitiate the potassium infusion through the saline-locked access and instruct the unlicensed assistive personnel to assess the site hourly for phlebitis.
Cevap
Connect a pre-mixed potassium chloride infusion to the saline-locked IV access and administer it via an electronic pump at a maximum rate of 10 mEq per hour.
The safest and standard practice for administering intravenous potassium chloride is to use a pre-mixed solution (to avoid mixing errors) and administer it via an electronic infusion pump. For a peripheral intravenous line, the maximum safe infusion rate is 10 mEq per hour to prevent burning at the site and to avoid life-threatening cardiac arrhythmias.
