Question

A 62-year-old with hypertension and T2DM presents with DKA: glucose 520 mg/dL, pH 7.12, bicarbonate 10 mEq/L, K⁺ 3.1 mEq/L. What is the correct initial insulin/fluid strategy?

Accepted Answer

Delay insulin until K⁺ ≥3.3 mEq/L while giving fluids and potassium

Answer

Start insulin infusion immediately at 0.1 U/kg/h

Answer

Give bolus insulin 0.3 U/kg then infusion

Answer

Start bicarbonate infusion regardless of pH

Answer

Restrict fluids until K⁺ normalises
