A nurse is assisting with preparations for administering intravenous potassium replacement supplements to a client who has a potassium level of 2.5 mg Which of the following actions should the nurse plan to include?

A. Place the patient on a cardiac monitor and check the patency of the IV: Hypokalemia (K+ = 2.5 mEq/L) can cause life-threatening cardiac dysrhythmias, so cardiac monitoring is essential. Additionally, potassium is highly irritating to veins, so IV patency must be confirmed to prevent extravasation and tissue damage. B. Administer potassium intravenously in an IV push bolus- NEVER give potassium IV push as it can cause fatal cardiac arrest. Potassium must always be diluted and infused slowly. C. Discontinue other medications that may affect potassium levels- Adjusting medications may be necessary, but not an immediate priority over cardiac monitoring. D. Avoid potassium-rich foods in the diet - Incorrect because the client needs potassium replacement, not restriction.
