Emergency Medical Technician (EMT) Basic Certification Practice Exam

What is the primary action of oral glucose when administered?

1. Increases blood sugar levels

2. Reduces hypertension

3. Stimulates insulin production

4. Decreases appetite

The correct answer is: Increases blood sugar levels

Oral glucose is primarily administered to quickly elevate blood sugar levels in individuals experiencing hypoglycemia, which is a condition characterized by abnormally low blood glucose. When consumed, glucose is absorbed into the bloodstream, resulting in an increase in blood sugar levels, providing an immediate source of energy for the body's cells. This is especially critical for patients who are conscious and able to swallow, as it helps to prevent severe complications from low blood sugar, particularly in conditions such as diabetes. The other options do not accurately describe the primary action of oral glucose. Reducing hypertension would involve medications or interventions unrelated to glucose administration. Stimulating insulin production is typically a function of the pancreas in response to increased blood sugar levels, not an action of oral glucose itself. Additionally, while glucose can impact appetite, this is not its primary role in emergency medical situations. The focus is squarely on its ability to restore glucose levels, making the correct answer significant in the context of emergency response and treatment protocols.
