For the nurse
Check the potassium level and kidney function first. Give oral forms with food and a full glass of water, and do not crush extended-release tablets. Mix powders and liquids well in juice or water. IV potassium is never given by IV push or as a bolus; it runs diluted on a pump. Concentrated potassium for injection is an ISMP high-alert drug.
