Final answer:
Benzodiazepines such as Valium (diazepam) can decrease anxiety symptoms by enhancing the effects of GABA in the brain.
Step-by-step explanation:
When administering a benzodiazepine such as Valium (diazepam), one sign to look for is a decrease in anxiety symptoms. Benzodiazepines are commonly used to treat anxiety disorders and work by enhancing the effects of a natural chemical in the brain called gamma-aminobutyric acid (GABA), which helps to calm down overexcited nerve cells. By reducing feelings of anxiety, benzodiazepines can help to promote relaxation and reduce symptoms such as restlessness, irritability, and trouble sleeping.
