A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

  • A. Administer IV calcium gluconate.
  • B. Administer sodium polystyrene sulfonate (Kayexalate).
  • C. Administer insulin with dextrose.
  • D. Restrict potassium intake in the client's diet.
Correct Answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.
