manifestations would the nurse expect to note in this client if excess fluid volume is present?

Chapter 8: Potassium chloride intravenously is prescribed for a client with heart failure
experiencing 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.
