Alcohol EffectsQuestion 33 of 100
A 'blackout' from alcohol consumption refers to:
a.Falling asleep at the bar from drowsiness
b.Permanent loss of vision
c.Loss of consciousness with hospitalization required
d.Failure of the brain to encode memories of events while still appearing awake and functional
Explanation
An alcohol-induced blackout is a memory-encoding failure of the hippocampus that occurs typically above 0.16% BAC. The drinker may walk, talk, and even drive home with no memory the next day. Blackout drinkers are extremely high risk: still legally drunk, often disinhibited, and prone to victimization or violence. Loss of consciousness (passing out) is a separate, even more severe stage. A patron showing blackout behavior (repeating themselves, not recognizing companions) requires immediate cut-off and safe transport.
