Electrolytes Question #68


A client with severe hypokalemia is prescribed intravenous potassium. In which way will the nurse administer the medication?


  1. In 100 mL diluent over 1 hour
    • Rationale:
  2. Rapid IV push
    • Rationale:
  3. Slow IV push in 10cc diluent over 3 minutes
    • Rationale:
  4. By administering oral K-Dur as a one-time dose
    • Rationale:



The correct answer is A. Potassium solutions should never be given as a push, and should always be given as a diluent. Giving it as a diluent over 1 hour will give the potassium time to even out the levels of potassium in the body, and prevent a rapid increase in potassium level. High concentrations of potassium are damaging to smaller peripheral veins. The nurse cannot change the route to administer the potassium supplement.

NCLEX TIP: Using critical thinking is recommended when reading priority questions. Recognizing key words in the answer choices will allow you to know how to choose the correct answer for the question. Go through each answer choice and decide is it: Maslow’s hierarchy, safety-related, or following the nursing process (ADPIE). Never complete a nursing action that is outside the scope of practice.
