Correct answer: D — Start fixed-rate insulin and continue basal insulin

Adult DKA is treated with fixed-rate intravenous insulin after initial assessment, while the person’s usual basal long-acting insulin is continued. This suppresses ketogenesis and helps transition after resolution; correction-bolus or glucose-led strategies are unsuitable.
