At a level of 250 mg/dl alcohol will cause nystagmus, marked slurring of speech and blackouts.

A

True. Between 200 – 300 mg/dl a person could manifest with the mentioned symptoms of alcohol intoxication.

65
Q

blood ethanol concentration of 300 mg/ml would likely to cause damage in this area of the brain
