Which intervention is critical in the treatment of DKA?

Immediate insulin administration is critical in the treatment of diabetic ketoacidosis (DKA) because it directly addresses the underlying hyperglycemia and promotes the uptake of glucose into the cells. DKA is characterized by a combination of insulin deficiency and increased levels of counter-regulatory hormones, which leads to the production of ketones and significant metabolic acidosis. Administering insulin helps to reduce blood glucose levels, halt ketogenesis, and correct the metabolic acidosis over time.

In addition to insulin, other supportive measures such as fluid resuscitation and electrolyte management are important; however, without the immediate action of insulin, the body's glucose control and ketone production cannot be effectively managed. Thus, insulin administration is a first-line intervention that significantly impacts the overall treatment and recovery of patients experiencing DKA.
