When evaluating a client for alcohol use disorder, which behavior warrants concern?

• A. Consuming alcohol socially
• B. Increasing tolerance to alcohol
• C. Feeling tired after consumption
• D. Utilizing alcohol to celebrate

Answer: (B)

Increasing tolerance to alcohol is a behavior that warrants significant concern when evaluating a client for alcohol use disorder. Tolerance refers to the body's adaptation to alcohol, where increasing amounts are needed to achieve the same effects that were previously experienced with smaller amounts. This can be a key indicator of developing dependence on alcohol. As a person increases their consumption, they may begin to rely on it more heavily, indicating a potential progression toward an alcohol use disorder.

In contrast, consuming alcohol socially is often a normative behavior in many cultures and does not in itself indicate a problem. Feeling tired after consumption can happen to anyone and alone does not signify a use disorder; it may simply reflect the effects of alcohol or individual health factors. Utilizing alcohol to celebrate is also a common practice, seen as a part of festivities and social events, and does not necessarily reflect problematic use unless accompanied by other concerning behaviors. Thus, increasing tolerance is a critical sign of a developing alcohol use disorder, alerting professionals to the need for further evaluation and intervention.
