Which of the following blood glucose values is outside the expected reference range?

Rationale

105 mg/dL is outside the expected reference range for blood glucose values.

The typical reference range for fasting blood glucose is generally considered to be between 70 mg/dL and 99 mg/dL. A value of 105 mg/dL exceeds this threshold, indicating potential hyperglycemia and a need for further evaluation.

A (85 mg/dL) YOUR ANSWER

This value falls within the normal reference range for fasting blood glucose, which is generally accepted to be between 70 mg/dL and 99 mg/dL. An 85 mg/dL reading is considered healthy and indicates normal glucose metabolism.

B (105 mg/dL) CORRECT

This reading is above the normal fasting range and indicates a level of hyperglycemia. Values above 100 mg/dL suggest a possible risk for prediabetes or diabetes, necessitating further assessment and monitoring of blood glucose levels.

C (95 mg/dL) YOUR ANSWER

A blood glucose level of 95 mg/dL is also within the normal reference range. It reflects adequate glucose regulation and is typical for a fasting blood glucose measurement, indicating no immediate concern for metabolic disorders.

D (75 mg/dL) YOUR ANSWER

This value is well within the normal reference range for blood glucose. A reading of 75 mg/dL indicates proper glucose control, and it is considered a healthy level for fasting blood glucose.

Conclusion

Understanding blood glucose values is crucial for identifying potential metabolic issues. Among the given choices, 105 mg/dL is the only level that exceeds the established reference range, suggesting a need for medical attention. The other values indicate normal glucose metabolism, highlighting the importance of monitoring and maintaining healthy blood sugar levels to prevent conditions like diabetes.
