Initial management of HHNK focuses on what primary step?

• A. Aggressive IV fluid resuscitation with isotonic saline
• B. Immediate insulin therapy without fluids
• C. Dialysis
• D. Oral hypoglycemics

Answer: (A)

In HHNK, the top priority is restoring circulating volume because severe dehydration from osmotic diuresis is life-threatening. Starting aggressive intravenous fluid resuscitation with isotonic saline rehydrates the patient, improves renal perfusion, and helps dilute the hyperosmolar state. This initial step also lays the groundwork for effective glucose reduction and electrolyte stabilization.

Insulin therapy is essential, but it is started after fluids have begun correcting the volume status. Administering insulin too early, without adequate fluids, can precipitate dangerous shifts in fluids and potassium, and may worsen blood pressure and perfusion.

Dialysis isn’t the first move; it’s reserved for specific situations such as refractory hyperglycemia with renal failure or severe electrolyte disturbances that don’t respond to fluids and insulin. Oral hypoglycemics aren’t appropriate in the acute HHNK situation because they don’t act quickly enough to correct the profound dehydration and hyperglycemia.
