A 35-year-old female with Type 1 Diabetes Mellitus presents to the ED with altered mental status, polyuria, polydipsia, and abdominal pain. Labs show glucose 650 mg/dL, pH 7.15, bicarbonate 8 mEq/L, and positive urine ketones. After securing airway and initiating intravenous fluids, what is the MOST appropriate next step in her medical management?
✓ Correct Answer: Option B
For diabetic ketoacidosis (DKA), after initial fluid resuscitation, a continuous intravenous insulin infusion is crucial. It gradually lowers glucose, suppresses ketogenesis, and allows for careful electrolyte monitoring and correction.
