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?
2-hr blood glucose 132 mg/dL.
HbA1c 5.2%.
Casual blood glucose 178 mg/dL.
Fasting blood glucose 155 mg/dL. .
The Correct Answer is D
Choice A rationale
A 2-hour blood glucose level of 132 mg/dL is below the threshold for diabetes diagnosis, which is 200 mg/dL or higher.
Choice B rationale
An HbA1c level of 5.2% is within the normal range. Diabetes is diagnosed with an HbA1c of 6.5% or higher.
Choice C rationale
A casual blood glucose level of 178 mg/dL is elevated but not diagnostic of diabetes. Diabetes is diagnosed with a casual blood glucose level of 200 mg/dL or higher.
Choice D rationale
A fasting blood glucose level of 155 mg/dL is above the threshold for diabetes diagnosis, which is 126 mg/dL or higher. This indicates that the client is at risk for diabetes mellitus.

Correct Answer is C
Explanation
Choice A rationale
Metabolic acidosis is incorrect. Metabolic acidosis is characterized by a low pH and low HCO₃ levels. In this case, the HCO₃ level is normal, which rules out metabolic acidosis.
Choice B rationale
Metabolic alkalosis is incorrect. Metabolic alkalosis is characterized by a high pH and high HCO₃ levels. In this case, the pH is low, and the HCO₃ level is normal, which rules out metabolic alkalosis.
Choice C rationale
Respiratory acidosis is correct. Respiratory acidosis is characterized by a low pH and high PaCO₂ levels. In this case, the pH is 7.24 (low), and the PaCO₂ is 53 (high), indicating respiratory acidosis. This condition occurs when there is an accumulation of CO₂ in the blood due to inadequate ventilation.
Choice D rationale
Respiratory alkalosis is incorrect. Respiratory alkalosis is characterized by a high pH and low PaCO₂ levels. In this case, the pH is low, and the PaCO₂ is high, which rules out respiratory alkalosis.
