Registered Practical Nurse (RPN) Practice Test

If a client has a blood alcohol level of 0.10 following an accident, which effect should the nurse explain to family members?

1. Increased alertness

2. Impaired speech

3. Sedation

4. Heightened anxiety

The correct answer is: Sedation

In the context of a blood alcohol level of 0.10, the effects of alcohol on the central nervous system become quite significant. At this level, individuals typically experience sedation, which is characterized by drowsiness and a reduced level of consciousness. This level of alcohol consumption results in the depressant effects of alcohol becoming pronounced, leading to a decrease in the person's ability to remain alert and responsive. While some might incorrectly assume that a person could feel more anxious or alert, the reality is that a blood alcohol concentration of 0.10 impairs cognitive and motor functions, often leading to sedation. This means that the person may not only appear relaxed but may also experience difficulties in thinking clearly or responding rapidly to stimuli, making sedation a key effect to explain to family members.
