A 75-year-old female patent is admitted to the hospital complaining of symptoms of hyponatremia, with a noticeable decrease in mental status. A full Basic Metabolic Panel (BMP) was ordered, revealing hyperkalemia (K⁺ = 7.0 mEq/L). Given the risk of life-threatening cardiac arrhythmias, which of the following medications should be administered first to protect the heart?

With K⁺ > 6 (here 7.0) the first priority is to stabilize the cardiac membrane with IV calcium gluconate. It does not lower potassium, but it protects against arrhythmia while other measures work.
- Insulin and β-agonists shift K⁺ into cells and loop diuretics excrete it; these come next, not first.
