How does body weight affect the amount of alcohol it takes to raise a person's BAC?
- The heavier the person, the less alcohol it takes
- The heavier the person, the more alcohol it takes
- Body weight has no effect on BAC
- Only height decides how fast BAC rises
Show answer
Correct answer: The heavier the person, the more alcohol it takes
A heavier person needs more alcohol to reach the same BAC, so a smaller person who matches friends drink for drink will probably be affected sooner.

Two people weigh the same and each has the same number of drinks. Which one will show signs of intoxication first?
- The one with less body fat
- The one who is taller
- Both show signs at exactly the same moment

What effect does food in the stomach have on alcohol?
- It causes alcohol to be absorbed more slowly

- It makes alcohol be absorbed faster
- It lets the liver oxidize alcohol faster
Show answer

-
If the liver is damaged or diseased, what happens to the rate at which it oxidizes alcohol?
- It increases, so alcohol leaves the body faster
- It is reduced, so alcohol stays in the body longer
- It stays the same, since only time sobers a person
- It is unaffected, but BAC drops faster
Show answer
Correct answer: It is reduced, so alcohol stays in the body longer
A damaged liver oxidizes alcohol more slowly, so the alcohol stays in the body longer and the BAC stays higher for longer.
