Which treatment is crucial for improving patients with metabolic acidosis caused by diabetic ketoacidosis (DKA)?

The treatment that is crucial for improving patients with metabolic acidosis caused by diabetic ketoacidosis (DKA) is the correction of hyperglycemia. DKA is characterized by high blood glucose levels, insulin deficiency, and the accumulation of ketones, leading to metabolic acidosis. By addressing hyperglycemia, typically through the administration of insulin, the underlying cause of the acidosis is tackled. Insulin helps to lower blood glucose levels and promotes the utilization of glucose by the cells, which decreases lipolysis and ketogenesis, ultimately reducing the production of ketone bodies responsible for the acidosis.

While intravenous fluids can be supportive in the overall management of DKA by ensuring adequate hydration and helping to restore electrolyte balance, they do not directly correct the metabolic acidosis. Similarly, the exclusive use of bicarbonate is not usually indicated in the management of DKA unless the acidosis is severe (pH < 6.9), as it does not address the underlying problem of hyperglycemia and can potentially contribute to complications. Immediate dialysis is generally not indicated for DKA and is reserved for cases of renal failure or severe electrolyte imbalances, as most DKA patients can be managed effectively with fluid, insulin, and electrolyte replacement. Therefore, correcting
