Final answer:
The nurse should report the Blood glucose level of 200 mg/dL to the provider, as it indicates that the patient's glucose levels are still considerably high and may require intervention.
Step-by-step explanation:
A nurse reviewing the medical record of a client with diabetic ketoacidosis receiving insulin by continuous IV infusion should report a Blood glucose level of 200 mg/dL. This level indicates that the patient's blood glucose is still significantly elevated and may require adjustments to the insulin protocol. Although a blood glucose level below 180 mg/dL is typically not associated with glucose excretion in the urine (glucosuria), a level of 200 mg/dL is above this threshold and may signify inadequate insulin activity or a complication in diabetes management.
