Pharmacological and Parenteral TherapiesQuestion 207 of 2368

A client with hyperkalemia is prescribed IV calcium gluconate. What is the purpose of this medication?

  1. To permanently lower the serum potassium level by removing it from the body
  2. To protect the heart from the effects of excess potassium for a short time
  3. To bind potassium in the intestine so it is removed through the GI tract
  4. To shift potassium from the bloodstream back into the cells over several hours
Show answer

Correct answer: To bind potassium in the intestine so it is removed through the GI tract

Calcium gluconate is a temporary measure. It buys time for other treatments to lower potassium before cardiac arrest develops.
