Which intervention is part of initial management for DKA?

• A. Fluid resuscitation to improve perfusion and insulin delivery.
• B. Beta-blocker therapy to reduce heart rate.
• C. High-dose calcium chelation.
• D. Sedation with benzodiazepines

Answer: (A)

Initial management of DKA prioritizes restoring intravascular volume to improve perfusion and enable insulin delivery. Dehydration with compromised perfusion drives the metabolic crisis, so giving IV fluids—starting with isotonic saline—helps quickly restore circulating volume, enhance renal perfusion, and facilitate rapid distribution of insulin once therapy is begun. As fluids are given, electrolytes, especially potassium, must be monitored because insulin administration and fluid shifts can cause potassium to move into cells, risking hypokalemia; this is why careful electrolyte management accompanies fluid resuscitation and insulin therapy. Beta-blocker therapy, high-dose calcium chelation, and sedation with benzodiazepines do not address the underlying metabolic crisis of DKA and are not part of the initial stabilization. Beta-blockers can mask signs of hypoperfusion and complicate support; calcium chelation is used for toxic metal exposures, not DKA; benzodiazepines could worsen respiratory status and delay stabilization in a fluid-replete, electrolyte-correcting process. The essential first step is fluid resuscitation to restore perfusion and support subsequent insulin and electrolyte management.
