What bicarbonate level is specified as a treatment goal in DKA?

• A. ≤10 mEq/L
• B. 25 mEq/L
• C. ≥18 mEq/L
• D. 30 mEq/L

Answer: (C)

In DKA, bicarbonate is considered only for the most severe acidemia, because correcting acid-base status must be balanced against risks of overshoot. When bicarbonate is used, the treatment goal is to raise the serum bicarbonate to about 18 mEq/L or higher. This level provides meaningful correction of acidosis to improve hemodynamics and perfusion without pushing bicarbonate beyond a safe range, which can cause electrolyte disturbances or other complications. Numbers much lower than 18 reflect undercorrection, while higher values (like 25 or 30) overshoot and increase risk, so aiming for roughly 18 mEq/L is the best target.
