How many mEq of K do you need to give a patient to increase plasma concentration of K by 1 mEq?,”~200 mEq. (100-200 mEq addition to increase 1 mEq/L above 4 mEq/L, 200-400 mEq loss to decrease 1 mEq/L below 4 mEq/L)This is due to the fact that most K is intracellular
so any you give also moves intracellular quickly.”
