North Carolina EMT-Basic (EMT-B) State Practice Exam – Practice Test & Prep

A normal fasting glucose reading in adults typically ranges from 70 to 100 mg/dL. This measurement is crucial for assessing how well the body manages blood glucose levels when not influenced by recent food intake. Fasting means that the individual has not consumed any calories for at least eight hours before the test.

In this context, the correct range reflects the values that are considered to indicate normal metabolism of glucose and is important for diagnosing conditions such as diabetes or prediabetes. Understanding these ranges is critical for EMT-Basics as it forms the foundation for assessing patients who may present with symptoms of hypoglycemia or hyperglycemia.

While the chosen option includes a higher upper limit, it exceeds the standard reference range for normal fasting glucose levels. This means that the outcomes provided in the other options either overestimate or underestimate the expected normal values, which is why they are not considered accurate.
