DUI DUI Substance Abuse Assessment and Intervention 1 — Questions and Answers
Question 1: Which standardized screening tool is most commonly used by DUI instructors and counselors to assess alcohol use disorder?
- CAGE Questionnaire
- PHQ-9
- GAD-7
- AUDIT-C (Correct answer)
Correct answer: AUDIT-C
The AUDIT-C (Alcohol Use Disorders Identification Test – Consumption) is a widely validated brief screening tool used to identify hazardous or harmful alcohol consumption in DUI contexts.
Question 2: What blood alcohol concentration (BAC) level is the legal limit for operating a vehicle for non-commercial adult drivers in all US states?
- 0.05%
- 0.08% (Correct answer)
- 0.10%
- 0.15%
Correct answer: 0.08%
All US states have established 0.08% BAC as the per se legal limit for adult non-commercial drivers, meaning driving at or above this level is automatically unlawful.
Question 3: Which factor most significantly affects how quickly alcohol is absorbed into the bloodstream?
- The color of the alcoholic beverage
- Whether food is present in the stomach (Correct answer)
- The temperature of the drink
- The drinker's eye color
Correct answer: Whether food is present in the stomach
Food in the stomach slows gastric emptying, which delays alcohol absorption into the small intestine and bloodstream, resulting in a lower and slower BAC rise.
Question 4: What is the approximate rate at which the liver metabolizes alcohol in a typical adult?
- 0.005% BAC per hour
- 0.015% BAC per hour (Correct answer)
- 0.05% BAC per hour
- 0.10% BAC per hour
Correct answer: 0.015% BAC per hour
On average, the liver metabolizes alcohol at a rate of approximately 0.015% BAC per hour, which is roughly equivalent to one standard drink per hour.
Question 5: In the DSM-5, how many criteria must be met within a 12-month period to diagnose 'severe' Alcohol Use Disorder?
- 2 or 3 criteria
- 4 or 5 criteria
- 6 or more criteria (Correct answer)
- 11 criteria exactly
Correct answer: 6 or more criteria
The DSM-5 defines severe Alcohol Use Disorder as the presence of 6 or more of the 11 diagnostic criteria within a 12-month period.
Question 6: Which term describes the physical state requiring increasing amounts of alcohol to achieve the same effect?
- Dependence
- Tolerance (Correct answer)
- Withdrawal
- Craving
Correct answer: Tolerance
Tolerance is the neurological adaptation in which repeated alcohol use causes the brain to require higher doses to produce the same euphoric or sedative effect.
