The most important step in severe<unk>  is removing the cause, such as treating diarrhea or stopping offending medication. The oral route for potassium repletion (40 mEq KCL, PO, Q 4-6 hours) is the safest.  Severe<unk>  can be treated via IV KCl infusion (10 mEq/hour KCL) with doses that shouldn't exceed 60 mEq/L unless ECG monitoring is provided. A central line can be used for administration of greater concentrations of KCl.
