In a patient with DKA, what is the initial priority in correcting the electrolyte imbalance?

Rationale: A. Hypomagnesemia may occur in DKA, but magnesium is not the initial priority. Correcting potassium and fluid deficits takes precedence, as potassium imbalances can rapidly become life-threatening due to cardiac arrhythmias. B. Potassium replacement is the initial priority when treating DKA because insulin therapy drives potassium into cells, which can precipitate severe hypokalemia. Before or alongside insulin administration, serum potassium must be checked and replaced as needed to maintain safe cardiac function. Potassium restoration is critical even if serum potassium initially appears normal, as levels can drop quickly once treatment begins. C. Calcium is generally not a primary concern in acute DKA management unless a deficiency is documented. Focus remains on potassium, sodium, and fluid balance. D. Sodium may be affected by hyperglycemia and osmotic diuresis, but sodium correction is secondary. Rapid sodium correction is avoided to prevent cerebral edema. Initial priority is potassium stabilization.
