Potassium level elevation demands immediate attention because it directly threatens heart rhythm. A potassium of 5.6 mEq/L is above the normal range and can quickly progress from subtle ECG changes to life-threatening arrhythmias if not treated promptly. The heart relies on precise extracellular potassium for electrical conduction, so even a modest rise can destabilize rhythm; thus continuous cardiac monitoring and rapid measures to lower potassium are prioritized.

In this scenario, the sodium is mildly low (hyponatremia at 130) and glucose is normal, so they’re not the urgent threat to stability. Hypokalemia isn’t present, and hyperglycemia isn’t present either, so those choices don’t carry the same immediate risk. Addressing hyperkalemia now helps prevent potentially fatal cardiac events.
