Question

On average, after a person reaches a peak BAC, it will drop by __________ per hour.

A) 0.02 per hour
B) 0.05 per hour
C) 0.10 per hour
D) 0.15 per hour

Answer 1

The average rate at which alcohol is cleared from the bloodstream after reaching peak BAC is approximately 0.015% per hour, and the closest answer choice to this rate is A) 0.02 per hour.

Step-by-step explanation:

According to available data on alcohol metabolism, the average rate at which alcohol is cleared from the bloodstream after reaching peak blood alcohol concentration (BAC) is approximately 3.3 mmol/L per hour, which is equivalent to about 15 mg/dL per hour.

When translated to percentages, this comes out to about 0.015% per hour. Since none of the answer choices matches this exact rate, the closest option would be A) 0.02 per hour, making this the most accurate choice from the given options. For an average person, this rate of decrease in BAC will be consistent regardless of the initial level of alcohol intake, as the liver metabolizes the alcohol at a fairly constant rate. However, factors such as gender, size, and individual liver function can cause some variance in this rate.
