For a 150 lb male drinking 12 drinks in an hour on an empty stomach, what would be the estimated BAC?

The correct answer is: .30

To understand the estimated Blood Alcohol Concentration (BAC) for a 150 lb male drinking 12 drinks in an hour on an empty stomach, it's important to consider the general rules of BAC calculation and the effects of consuming alcohol rapidly. Typically, BAC is calculated using the Widmark formula, which estimates BAC based on body weight, the number of drinks consumed, and a standard drink's alcohol content. A standard drink in the U.S. contains about 14 grams of pure alcohol. When consuming a large number of drinks in a short period, especially on an empty stomach, the body struggles to metabolize the alcohol, leading to a much higher BAC. Drinking 12 standard drinks in one hour would rapidly increase the BAC significantly. For a 150 lb male, consuming 12 drinks could potentially lead to a BAC around .30 or higher, which aligns with high intoxication levels that result from binge drinking. It is crucial to note that BAC values can vary based on individual metabolism, health conditions, and other factors. However, in terms of sheer volume consumed in a short time, the estimated BAC for someone in this scenario is closest to the value of .30, as this represents the threshold of severe impairment and risk of alcohol poisoning.
