What happens to BAC when a person continues to drink?

  1. It stays the same.

  2. It decreases.

  3. It rises.

  4. It fluctuates randomly.

The correct answer is: It rises.

When a person continues to drink, their Blood Alcohol Concentration (BAC) typically rises. This occurs because as alcohol is consumed, it enters the bloodstream and increases the amount of alcohol in the system. The liver metabolizes alcohol at a relatively constant rate, but if consumption exceeds this rate, BAC will increase. The continuous intake of alcohol does not allow the body enough time to process it effectively, leading to higher levels of intoxication over time. While some individuals may experience variations in BAC due to factors like metabolism, food intake, or hydration levels, the primary effect of continued drinking is a progressive increase in BAC. Therefore, the correct outcome is that BAC rises as one continues to consume alcohol.
