QUESTIONS AND RATIONALE
Potassium chloride intravenously is prescribed for a client with hypokalemia. Which actions should the
nurse take to plan for preparation and administration of the potassium? Select all that apply.
1. Obtain an intravenous (IV) infusion pump.
2.Monitor urine output during administration.
3.Prepare the medication for bolus administration.
4. Monitor the IV site for signs of infiltration or phlebitis.
5. Ensure that the medication is diluted in the appropriate volume of fluid.
6. Ensure that the bag is labeled so that it reads the volume of potassium in the solution. - CORRECT
ANSWER -1, 2, 4, 5, 6
Potassium chloride administered intravenously must always be diluted in IV fluid and infused via an
infusion pump. Potassium chloride is never given by bolus (IV push). Giving potassium chloride by IV
push can result in cardiac arrest. The nurse should ensure that the potassium is diluted in the
appropriate amount of diluent or fluid. The IV bag containing the potassium chloride should always be
labeled with the volume of potassium it contains. The IV site is monitored closely because potassium
chloride is irritating to the veins and there is risk of phlebitis. In addition, the nurse should monitor for
infiltration. The nurse monitors urinary output during administration and contacts the health care
provider if the urinary output is less than 30 mL/hour.
