Resins such as sodium polystyrene sulfonate are used to move potassium out of the body via the gastrointesti- nal tract. Each 1 g of resin administered orally removes approximately 1 mEq of potassium. Forced diuresis with a loop diuretics (e.g. furosemide) takes advantage of the potassium-wasting effects of furosemide. Loop diuretics act by blocking the tubular reabsorption of sodium in the loop of Henle and early distal tubule, thus increasing sodium delivery to the distal tubule and stimulating po- tassium excretion [17,18]. The ultimate therapy for hy- perkalemia due to iatrogenic causes is hemodialysis, but while waiting 50% dextrose and insulin may be given to push potassium into cells, NG suction and exchange res- ins may be given to remove potassium via the GI tract or IV calcium may be given to neutralize its effect on cel- lular membranes [19]. The latter provides the quickest protection
