The nurse is assigned to care for a patient who presented to the emergency department with diabetic ketoacidosis. A continuous insulin intravenous infusion is started, and hourly bedside glucose monitoring is ordered
The targeted blood glucose value after the first hour of therapy is: a. 70 to 120 mg/dL.
b. a decrease of 25 to 50 mg/dL compared with admitting values.
c. a decrease of 50 to 75 mg/dL compared with admitting values.
d. less than 200 mg/dL.
C
Initial insulin infusions should be administered with a target blood glucose reduction of 50 to 75 mg/dL per hour. Decreases of less than this rate may be associated with inadequate insulin replacement and allow for the persistence of the ketotic state. Rapid reductions of blood glucose may precipitate life-threatening cerebral edema; thus, controlled reduction of glucose is required.
