A nurse is checking the laboratory results of a client who is at risk for diabetes mellitus. Which of the following laboratory results indicates to the nurse that the client is at risk for diabetes mellitus?

A fasting blood glucose level of 155 mg/dL is above the normal threshold (greater than 126 mg/dL indicates diabetes).
A casual blood glucose of 178 mg/dL suggests hyperglycemia but does not meet the diagnostic criteria for diabetes unless associated with symptoms.
An HbA1c of 5.2% is well within the normal range (below 5.7%).
