What best describes the role of IV fluids in DKA/HHS treatment?

• A. Administer only potassium
• B. Raise total fluid volume and correct electrolyte imbalances
• C. Decrease glucose
• D. Prevent infection

Answer: (B)

The main idea is that IV fluids in DKA/HHS serve to restore intravascular volume and begin correcting dehydration and electrolyte losses. In both conditions, extreme fluid loss from osmotic diuresis leaves the patient severely dehydrated and with electrolyte abnormalities. Giving IV fluids, starting with isotonic saline, rehydrates the patient, improves renal perfusion, helps normalize blood pressure and perfusion to organs, and sets the stage for safe insulin therapy and electrolyte correction. As fluids are given, potassium and other electrolytes shift into their proper compartments, which is why electrolyte management is intertwined with fluid therapy. Potassium may be depleted even if it looks normal or high at first, and as insulin is started and acidosis resolves, serum potassium can drop quickly, necessitating careful monitoring and replacement. Once perfusion is restored and glucose falls to a safer level, fluids are adjusted to prevent hypoglycemia while continuing electrolyte correction. So the IV fluid strategy is best described as raising total fluid volume and correcting electrolyte imbalances, rather than solely lowering glucose, preventing infection, or administering potassium in isolation.
