What is the recommended initial management sequence for DKA?

• A. Begin isotonic saline, then immediately start insulin before addressing electrolytes
• B. Start with bicarbonate therapy before fluids
• C. Withhold fluids to prevent edema
• D. Begin isotonic saline promptly, monitor labs, initiate insulin after initial fluids if potassium allows, replete electrolytes

Answer: (D)

Managing DKA hinges on restoring circulation first, then bringing the metabolic disturbances under control with insulin and careful electrolyte management. Start with isotonic saline promptly to correct severe dehydration and improve tissue perfusion. While fluids are being given, monitor labs closely—especially potassium, as insulin therapy will shift potassium into cells and can precipitate dangerous hypokalemia if potassium is not already corrected. The insulin infusion is started after adequate fluid resuscitation and once potassium is in a safe range: if potassium is below 3.3 mEq/L, hold insulin and correct potassium first; if potassium is between 3.3 and 5.0, begin insulin and replenish potassium to maintain about 4–5 mEq/L; if potassium is above 5.0, start insulin with careful potassium monitoring and supplementation as needed. Replete electrolytes as indicated throughout treatment. Bicarbonate is reserved for the most severe acidosis (pH < 6.9) and not used routinely. Withholding fluids to prevent edema is not appropriate, because correcting dehydration and improving perfusion is the primary priority in the early phase of management.
