Answer

Hyperkalemia in patients with AKI can be life-threatening. Approaches to lowering serum potassium include the following:

  • Decreasing the intake of potassium in diet or tube feeds

  • Exchanging potassium across the gut lumen using potassium-binding resins

  • Promoting intracellular shifts in potassium with insulin, dextrose solutions, and beta agonists

  • Instituting dialysis
