To control hyperkalemia, what is one method that delivers potassium back into the cells?

The method of administering D5W with Insulin is effective in controlling hyperkalemia because insulin facilitates the uptake of potassium into the cells. When insulin is given, it promotes the transport of glucose along with potassium into the cells, thereby lowering serum potassium levels. This mechanism is especially beneficial in acute situations where rapid management of high potassium levels is essential, as it can quickly correct the hyperkalemic state.

Renal dialysis is indeed a treatment for hyperkalemia, but it functions by removing excess potassium from the bloodstream rather than redistributing it into cells. IV Calcium Gluconate is used to protect the heart from the effects of high potassium but does not actively move potassium into cells. Similarly, Furosemide is a diuretic that can help eliminate potassium through urine but does not address the immediate need to shift potassium back into cells. Thus, D5W combined with Insulin is the most direct and effective method among the options for redistributing potassium and correcting hyperkalemia.
