DKA, HHS, and Hypoglycemia: Managing Diabetic Emergencies in Nursing Care

In this episode, we break down the critical endocrine emergencies associated with diabetes, focusing on Diabetic Ketoacidosis (DKA), Hyperosmolar Hyperglycemic State (HHS), and severe hypoglycemia. We’ll compare the etiology and pathophysiology behind each condition, helping you understand why DKA leads to ketone production and acidosis, while HHS results in severe dehydration without ketosis.

You’ll learn how to recognize key differences in clinical manifestations, from the classic signs of hyperglycemia—such as polyuria, polydipsia, and altered mental status—to the rapid onset of hypoglycemia, including diaphoresis, confusion, and potential loss of consciousness.

We’ll also walk through management strategies, emphasizing the critical differences in treatment approaches: fluid resuscitation, insulin therapy, and electrolyte replacement for DKA and HHS, versus immediate glucose administration for hypoglycemia. Throughout the episode, we highlight essential nursing priorities, including frequent monitoring, patient safety, and early recognition of deterioration.

This episode equips nurses with the clinical reasoning and rapid-response skills needed to safely manage life-threatening diabetic emergencies in both acute and critical care settings.
