In diabetic ketoacidosis, what does the acronym SIPS stand for in pharmacologic management?

• A. SIPS = Saline, Insulin, Potassium, and Secondary evaluation
• B. SIPS = Steroids, Inotropes, Potassium, Sugars
• C. SIPS = Saline, Insulin, Potassium, Search for underlying cause
• D. SIPS = Sodium, Iodine, Phosphate, Sugars

Answer: (C)

SIPS in diabetic ketoacidosis highlights four essential actions: Saline, Insulin, Potassium, and Search for underlying cause. Begin with IV isotonic saline to correct severe dehydration and restore perfusion; fluids are continued and then dextrose is added when glucose approaches 200 mg/dL to prevent hypoglycemia while continuing insulin. After adequate fluid resuscitation, start insulin therapy to suppress ketogenesis and rapidly correct hyperglycemia and acidosis, with careful monitoring for shifts in potassium and glucose. Potassium management is crucial because total body potassium is depleted even if the serum level looks acceptable; insulin and fluids push potassium into cells, so you must monitor and replace to maintain a safe range (often around 4–5 mEq/L). Finally, identify and treat the underlying trigger driving the DKA—such as infection, nonadherence, or new-onset diabetes—to prevent recurrence. The inclusion of Search for underlying cause distinguishes the correct approach from options that misplace or omit this preventive step.
