In the management of diabetic ketoacidosis (DKA), which of the following is NOT typically part of the initial protocol?

• A. IV fluids: isotonic saline
• B. Regular insulin administration
• C. Bicarbonate in severe acidosis
• D. Potassium repletion

Answer: (C)

In managing DKA, the initial steps focus on volume resuscitation, stopping ketone production, and correcting electrolytes. Bicarbonate is not routinely given as part of this immediate protocol because, even though severe acidemia is dangerous, bicarbonate can introduce new problems and does not reliably improve outcomes in most DKA cases. It is reserved only for extreme acidemia, typically when the pH is very low (less than about 6.9), where potential benefits may outweigh risks. The standard initial approach is to start IV isotonic fluids to restore perfusion and correct dehydration. Once fluids are underway, insulin therapy with a regular insulin infusion is started to suppress ketogenesis and rapidly reduce hyperglycemia. Potassium repletion is also essential because total body potassium is depleted despite what the serum level may suggest; as fluids and insulin are given, potassium tends to shift into cells, risking hypokalemia, so potassium is monitored and repleted as needed. So, bicarbonate in severe acidosis is the exception rather than the rule in the early management of DKA.
