A client, diagnosed with type 2 diabetes mellitus, is hospitalized during the night with an infected foot ulcer. On admission, a physician writes an order to obtain fingerstick blood glucose levels four times per day before meals and at bedtime, to continue metformin XR (Glucophage®) 500 mg oral daily, and to administer 2 units aspart insulin subcutaneously three times a day, 5 minutes before meals. When reviewing the client’s medical record, the on-coming day shift nurse notes that the client has had suboptimal glycemic control with oral hypoglycemic agents. The client’s glycosylated hemoglobin level is 10.5%. Which should be the priority action for the on-coming day-shift nurse?
