What action should the nurse take before administering insulin to a client with hypokalemia?

Before administering insulin to a client with hypokalemia, it is crucial to contact the healthcare provider. Insulin promotes the uptake of glucose into cells, which also leads to an increase in potassium uptake. In clients with hypokalemia, administering insulin can exacerbate the low potassium levels, potentially leading to severe complications like cardiac arrhythmias.

By notifying the healthcare provider, the nurse ensures that the client’s electrolyte levels, particularly potassium, are carefully managed. The provider may decide to address the hypokalemia before insulin administration or may adjust the insulin dosage based on the client’s overall clinical picture. This proactive approach is vital for ensuring patient safety and effective management of their hypoglycemic condition.
