Hyperkalemia poses a direct and imminent risk of cardiac arrhythmias and cardiac arrest. The nurse must act as a safety net by promptly communicating this change in status to obtain urgent orders, such as IV calcium for cardioprotection or interventions to shift potassium intracellularly.
Do not delay notification to independently implement interventions like holding medications or adjusting fluid restrictions. These actions require a provider's order and do not treat the immediate threat of a potassium level above 5.0 mEq/L.
