Correct answer: AIV NS bolus then continuous insulin infusion

Paediatric DKA: IV 0.9% NS (10-20 mL/kg over 1-2h) then insulin infusion (0.05-0.1 U/kg/h) started 1-2h after fluids. CPS: avoid bicarbonate (risk paradoxical CNS acidosis and cerebral oedema). Cautious fluids to prevent cerebral oedema.
