Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Oral hypoglycemic agents are not appropriate in the acute setting of DKA as they may not work quickly enough. Sodium bicarbonate may be used in some cases to correct acidosis, but insulin administration takes precedence. Providing a high-calorie diet is not appropriate initially in DKA management, as the focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.
