TIPS Alcohol Physiology & Blood Alcohol Content 1 — Questions and Answers
Question 1: Approximately what percentage of consumed alcohol is absorbed into the bloodstream through the small intestine?
- 20%
- 50%
- 80% (Correct answer)
- 99%
Correct answer: 80%
About 80% of alcohol is absorbed through the small intestine, while roughly 20% is absorbed through the stomach lining.
Question 2: Which organ is primarily responsible for metabolizing alcohol in the human body?
- Kidneys
- Stomach
- Liver (Correct answer)
- Pancreas
Correct answer: Liver
The liver is the primary organ that metabolizes alcohol, processing approximately one standard drink per hour.
Question 3: On average, the liver can metabolize approximately how much alcohol per hour?
- Half a standard drink
- One standard drink (Correct answer)
- Two standard drinks
- Three standard drinks
Correct answer: One standard drink
The average liver metabolizes approximately one standard drink per hour, regardless of body weight or other factors.
Question 4: A standard drink in the United States contains approximately how many grams of pure alcohol?
- 7 grams
- 10 grams
- 14 grams (Correct answer)
- 20 grams
Correct answer: 14 grams
A U.S. standard drink contains 14 grams (0.6 ounces) of pure ethanol, equivalent across beer, wine, and spirits.
Question 5: Which of the following factors MOST significantly slows alcohol absorption into the bloodstream?
- Drinking carbonated mixers
- Having food in the stomach (Correct answer)
- Drinking quickly
- Mixing different types of alcohol
Correct answer: Having food in the stomach
Food in the stomach slows gastric emptying, reducing the rate at which alcohol passes to the small intestine and enters the bloodstream.
Question 6: Blood Alcohol Content (BAC) is measured as:
- Milligrams of alcohol per liter of urine
- Grams of alcohol per 100 milliliters of blood (Correct answer)
- Parts per thousand alcohol in exhaled breath
- Millimoles of ethanol per kilogram of body weight
Correct answer: Grams of alcohol per 100 milliliters of blood
BAC is expressed as grams of alcohol per 100 milliliters (deciliter) of blood, e.g., 0.08 means 0.08g per 100mL.
Question 7: Which statement about carbonated alcoholic beverages is accurate regarding absorption?
- Carbonation slows alcohol absorption significantly
- Carbonation has no effect on absorption rate
- Carbonation speeds up alcohol absorption by relaxing the pyloric valve (Correct answer)
- Carbonation reduces the alcohol content of the beverage
Correct answer: Carbonation speeds up alcohol absorption by relaxing the pyloric valve
Carbonation can speed alcohol absorption because carbon dioxide relaxes the pyloric valve, allowing alcohol to move more rapidly into the small intestine.
