The nurse is teaching a client who had been newly diagnosed with diabetes mellitus about blood glucose monitoring. The nurse should teach the client to report glucose levels that consistently exceed which level?

The normal blood glucose level ranges from 70 to 110 mg/dL (4 to 6 mmol/L), or as designated and preferred by the primary health care provider. The client with diabetes mellitus should be taught to report blood glucose levels that exceed 250 mg/dL (14.28 mmol/L), unless otherwise instructed by the primary health care provider. Options 1 and 2 are high levels but do not require primary health care provider notification. Option 4 is a high value; the client should report an elevated level before it reaches this point.
