Correct answer: ETreat as DKA with isotonic fluid, potassium-guided insulin and early dextrose

Explanation lettering: D = shown as B · E = shown as C · C = shown as D · B = shown as E

B is correct for SGLT2-associated euglycemic DKA; normal-range glucose does not remove the need for insulin to stop ketogenesis, while dextrose permits ongoing insulin. C, D, E and A misclassify a high-anion-gap ketotic acidosis with a characteristic drug exposure.
