A) Dialysis
B) Calcium gluconate
C) Sodium bicarbonate
D) Glucose 50% and insulin
E) Sodium polystyrene sulfonate (Kayexalate)

Several measures are available to reduce the serum potassium concentration,and the priority of implementation is usually based on the rapidity with which the measures are effective.Temporary measures that produce a rapid but transient effect are calcium gluconate,sodium bicarbonate,and glucose 50%,and insulin.Definitive but slower-acting measures are then implemented which include administration of a cation exchange resin such as sodium polystyrene sulfonate (Kayexalate),1 g/kg,administered orally or rectally,and/or dialysis.
