The nurse is caring for a client with a history of type 2 diabetes mellitus (DM) and hypertension who arrived at the clinic for a scheduled visit. Which finding should the nurse recognize as a possible complication?Reference Range: Creatinine 0.5 to 1.1 mg/dL (44 to 97 umol/L) Glycosylated hemoglobin (HbA1c) Good diabetic control: less than 7% White Blood Cell 5,000 to 10,000/mm3 (5 to 10 x 10^9/L) Fasting Blood Glucose 74 to 106 mg/dL (4.1 to 5.9 mmol/L)

Choice A reason: A fasting serum glucose level of 140 mg/dL (7.77 mmol/L) indicates hyperglycemia, which is elevated but not an immediate life-threatening complication. It suggests poor blood glucose control but does not directly indicate a complication specific to type 2 diabetes and hypertension. This value should prompt further evaluation and adjustments in diabetes management, but it is not as critical as other potential findings.Choice B reason: A glycosylated hemoglobin (A1c) level of 6.9% is within the range of good diabetic control. While it indicates the client has been managing their blood glucose levels relatively well over the past few months, it does not suggest a current complication. This value is used to assess long-term glucose control rather than acute issues.Choice C reason: A serum creatinine level of 1.6 mg/dL (141.44 umol/L) is elevated and indicates impaired kidney function. Clients with type 2 diabetes mellitus and hypertension are at increased risk for kidney disease, known as diabetic nephropathy or hypertensive nephropathy. Elevated creatinine levels suggest that the kidneys are not filtering waste products effectively, which is a significant complication that requires immediate attention and intervention.Choice D reason: A white blood cell (WBC) count of 11,000/mm3 (11 x 10^9/L) is slightly elevated and may suggest an infection or inflammation. However, it is not a specific complication related to type 2 diabetes mellitus and hypertension. Elevated WBC counts warrant further investigation to identify any underlying infection or inflammatory process, but it is not as directly related to diabetic or hypertensive complications as elevated serum creatinine.
