Which phrase correctly names the measurement used to describe how much alcohol is in the bloodstream?

• A. The volume of ethanol in the urine
• B. The rate of alcohol absorption in the stomach
• C. The total ethanol eliminated per hour
• D. Blood Alcohol Concentration

Answer: (D)

The measurement describing how much alcohol is in the bloodstream is Blood Alcohol Concentration. This term directly expresses the amount of ethanol present in the blood, usually shown as a percentage (like 0.08%) or as grams of ethanol per 100 milliliters of blood. It’s the standard way to indicate intoxication level and is used in medical care and law enforcement. Think of the other ideas as describing different processes rather than the actual amount in the blood at a moment. Volume of ethanol in urine would reflect what has already been excreted over time, not the current blood level. The rate of alcohol absorption in the stomach describes how quickly alcohol enters the bloodstream, not how much is currently circulating. Total ethanol eliminated per hour refers to how fast the body metabolizes and removes alcohol, not the present concentration in the blood. So, Blood Alcohol Concentration is the precise term for how much alcohol is in the bloodstream at a given moment.
