Electrolytes Question #45


The nurse is teaching a client about prescribed potassium replacement therapy. Which client statement indicates that teaching has been effective?


  1. “I should never crush the medication if I cannot swallow it.”
    • Rationale:
  2. “I will take the medication and wait 6 hours before eating.”
    • Rationale:
  3. “I will take my pulse and hold the drug if it is less than 60 beats per minute.”
    • Rationale:
  4. “I will increase my spironolactone if I start to have cramps in my muscles.”
    • Rationale:



The correct answer is A. Crushing the medication can cause throat irritation, nausea, and vomiting. All of the medication will also be released at once, instead of over the 24 hours, and therefore will not keep the potassium level at a steady level for the day. There is no reason for the client to wait 6 hours before eating. Potassium is not held for a low pulse. The client should take medication as prescribed and not increase the amount of a dose.

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.
