ServSafe Alcohol Assessment Practice Exam

To determine a person's Blood Alcohol Concentration (BAC), we can use the Widmark formula, which takes into account the weight of the person, the amount of alcohol consumed, and the distribution of alcohol in the body. In this scenario, we know that the woman weighs 180 pounds and consumed three mixed drinks that each contain 1½ ounces of 80-proof vodka. First, we need to calculate the total amount of alcohol consumed. Since 80-proof vodka contains 40% alcohol, we find that each mixed drink contains 0.6 ounces of pure alcohol (1½ ounces times 0.40). For three drinks, this totals to 1.8 ounces of pure alcohol. Next, converting ounces to grams (since there are approximately 28.35 grams in an ounce), we find that she consumed about 51 grams of alcohol (1.8 ounces times 28.35 grams). Using the Widmark formula, we can now estimate her BAC: - The formula is BAC = (Alcohol consumed in grams / (Body weight in grams × r)) - (metabolism rate × time). - For women, the average r value is approximately 0.55. Her weight in grams is about 81
