The normal blood glucose range for a person who has fasted for 8 to 12 hours is typically recognized as being within the range of 70 to 100 mg/dL, with some sources indicating that an upper threshold can extend up to 120 mg/dL without indicating a problem.

When considering the specific choice stating 80 to 90 mg/dL, this value falls comfortably within the normal fasting range, making it the most appropriate answer. Maintaining blood glucose within this range is crucial for bodily functions and can be indicative of good metabolic health.

The other options reflect blood glucose levels that either fall below the typical threshold or suggest abnormal elevation, which may indicate hypoglycemia or hyperglycemia, respectively, neither of which would be considered normal in a fasting state. This understanding is pivotal in evaluating glucose levels, especially in emergency medical situations where accurate assessments are crucial for patient care.
