Question

all of the following are effects of alcohol at 0.05 g/dl bac, except:
a) lowered alertness.
b) some euphoria.
c) feeling of relaxation.
d) unsteady gait.

Explanation:

At a Blood Alcohol Concentration (BAC) of 0.05 g/dL, common effects include lowered alertness (as alcohol starts to affect the central nervous system), some euphoria (due to the release of neurotransmitters like dopamine), and a feeling of relaxation (as the inhibitory effects of alcohol start to take place). However, an unsteady gait typically occurs at a higher BAC (usually around 0.10 - 0.15 g/dL or more) when the motor skills are more significantly impaired.

Answer:

d) unsteady gait.
