Question

question # 9
multiple choice
the impairment and intoxication effects of alcohol are directly related to bac levels. which of the following levels is not correctly described?

○ euphoria: bac = 0.04 - 0.10 percent, flushed and shortened attention span
○ excitement: bac = 0.09 - 0.25 percent, becomes sleepy, has blurred vision, loses balance easily
○ confusion: bac = 0.18 - 0.30 percent, confused, dizzy, highly emotional, aggressive
○ stupor: bac = 0.25 - 0.40 percent, difficulty moving, unresponsive to stimuli, cannot stand or walk, in and out of consciousness

Explanation:

The question asks to identify the incorrectly described BAC level and effect. Euphoria typically occurs at lower BAC levels (around 0.03-0.12%), not 3.0-4.0% (which is a lethal range). Excitement at 0.00-0.25% with sleepiness/blurred vision is incorrect? Wait, no—let’s check standard BAC effects:

• Euphoria: ~0.03-0.12% (flushed, shortened attention) → Option A’s BAC (3.0-4.0%) is wrong (lethal, not euphoria).
• Excitement: ~0.09-0.25% has mild impairment, but 0.00 is sober. But Option B’s effects (sleepy, blurred vision) are for higher BAC, not excitement. Wait, the most clear error is Option A: 3.0-4.0% BAC is not euphoria (it’s coma/death).

Answer:

A. euphoria: BAC = 3.0-4.0 percent, flushed and shortened attention span
