The nurse is preparing to administer an intravenous infusion containing regular insulin for a patient diagnosed with diabetic ketoacidosis. Which of the following should the nurse plan to do while caring for this patient?
1. adjust the rate of infusion according to the blood glucose level
2. check blood glucose levels every 2 hours
3. monitor serum calcium levels closely
4. check urine for ketone bodies every shift
1
Rationale: Intravenous insulin infusions are adjusted to maintain a drop in blood glucose level at 50 to 70 mg/dL until desired blood glucose level is reached. Therefore, the rate of the infusion is adjusted according to the blood glucose level. Blood glucose levels need to be checked hourly. Sodium, potassium, and phosphorus levels should be checked and supplements given as needed. Blood glucose levels are much more accurate than urinary ketones.
