Alcohol intoxication occurs at blood levels between which values?

• A. 0 and 50
• B. 50 and 100
• C. 200 and 300
• D. 100 and 200

Answer: (D)

Alcohol intoxication is typically defined by a blood alcohol concentration of about 0.10% to 0.20% (100–200 mg/dL). At this level, noticeable impairment in coordination, judgment, and reaction time appears, along with changes in mood or behavior. Lower ranges (0–50 mg/dL or 50–100 mg/dL) may cause mild effects but not full intoxication, while higher ranges (200–300 mg/dL) can lead to more severe impairment, stupor, or potential loss of consciousness. Therefore, 100–200 mg/dL best fits the level at which intoxication occurs. In mental health care, recognizing this helps guide safety monitoring and intervention planning.
