Final answer:
BAC does not necessarily stop rising after a person stops drinking, as alcohol continues to be absorbed and metabolized over time.
Step-by-step explanation:
It's false that BAC stops rising after a person stops drinking. BAC can continue to increase as the alcohol in the stomach and intestines continues to be absorbed into the bloodstream, even after one stops consuming alcohol. Metabolizing alcohol takes time, and the liver breaks it down at a consistent rate, approximately 3.3 mmol/L (15 mg/dL) per hour. This process is not accelerated by common myths such as drinking coffee or taking a shower. Additionally, the effects of alcohol, such as the frequent need to urinate and the risk of dehydration as described in the Drink and Flush case study, can continue to manifest while BAC is elevated.
