What is the purpose of IV calcium gluconate in severe hyperkalemia?
- A. To push potassium back into the cells
- B. To protect cardiac muscle temporarily (correct answer)
- C. To bind potassium for removal in stool
- D. To increase potassium loss in urine
From the textbook“IV calcium gluconate may also be given to prevent excess potassium from affecting cardiac muscle. This is a temporary measure and wears off quickly but allows time for other treatments to take effect and lower potassium levels before cardiac arrest develops.”
