Which of the following are common symptoms of impairment?

The choice that reflects common symptoms of impairment is the one that identifies slowed reactions and impaired judgment. Impairment from substances, particularly alcohol and drugs, often affects cognitive functions and physical responses.

When a person is impaired, their ability to process information quickly decreases, leading to slower reactions in situations that require immediate decisions or actions. This delayed response time can significantly increase the risk of accidents, especially in contexts like driving. Additionally, impaired judgment affects a person's ability to assess situations and make sound decisions, which can lead to risky behaviors or inability to recognize danger.

The other choices suggest characteristics that typically do not coincide with impairment. For instance, increased alertness and enhanced coordination are generally signs of sobriety rather than impairment. While excessive enthusiasm may occur in some contexts, it does not specifically represent the cognitive and physical deficits associated with impairment as effectively as slowed reactions and impaired judgment do.
