On an empty stomach, what percentage of a single dose of alcohol is rapidly absorbed directly into the blood through the stomach?

The correct choice indicates that approximately 20% of a single dose of alcohol is rapidly absorbed directly into the bloodstream through the stomach when consumed on an empty stomach. This figure is significant because it emphasizes how quickly alcohol can begin to affect the body, particularly influencing judgment, coordination, and reaction times, all of which are critical when considering behaviors like driving.

When alcohol is ingested, its absorption rate varies based on several factors, including the presence of food in the stomach. When no food is present, alcohol passes through the stomach and into the small intestine more rapidly—where about 80% of alcohol is ultimately absorbed. This rapid absorption without food can lead to quicker intoxication, as the body has less time to process the alcohol before it enters the bloodstream.

Understanding the rate of alcohol absorption is crucial for recognizing the risks associated with drinking and driving, especially on an empty stomach, as it can significantly impair an individual’s abilities much faster than if they had eaten first.
