The nurse reviews the laboratory reports of a client and concludes that the client has diabetes. Which finding helped the nurse to reach this conclusion?
A glycated hemoglobin (HbA1c) value of 6.9
A postprandial blood glucose level of 170 mg/dL.
A confirmed fasting plasma glucose level of 100 mg/dL and a postprandial blood glucose level of 200 mg/dL
A fasting plasma glucose level of 90 mg/dL
The Correct Answer is C
Choice A rationale: A glycated hemoglobin (HbA1c) value of 6.9 indicates that the client has prediabetes, which is a risk factor for developing diabetes.
Choice B rationale: A postprandial blood glucose level of 170 mg/dL is within the normal range.
Choice C rationale: This indicates that the client has diabetes mellitus. According to the American Diabetes Association, a diagnosis of diabetes can be made if one of the
following criteria is met: a fasting plasma glucose level of 126 mg/dL or higher, a postprandial blood glucose level of 200 mg/dL or higher, or an HbA1c value of 6.5% or higher.
Choice D rationale: A fasting plasma glucose level of 90 mg/dL is within the normal range.
