Cardiovascular Pharmacology

1. 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

Rationale: 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. The following are all the option DIVs for the

individual question types They should be the same size as the option-area DIV above.

2. A client with atrial fibrillation is receiving a continuous heparin infusion at 1000 units/hour. The

nurse determines that the client is receiving the therapeutic effect based on which results?

1. Prothrombin time of 12.5 seconds

2. Activated partial thromboplastin time of 60 seconds

3. Activated partial thromboplastin time of 28 seconds

4. Activated partial thromboplastin time longer than 120 seconds

Correct answer: 2
