Luz is exploring the role of neurotransmitters in anxiety disorders. Which neurotransmitter is known for its inhibitory effects and is often targeted in anxiety treatments?
Glutamate.
Dopamine.
GABA.
Norepinephrine.
The Correct Answer is C
Choice A reason: Glutamate is the primary excitatory neurotransmitter in the brain, promoting neuronal activity. It is not typically targeted for its inhibitory effects in anxiety treatments, as excessive glutamate activity may contribute to heightened anxiety or overstimulation.
Choice B reason: Dopamine is involved in reward, motivation, and movement regulation. While imbalances in dopamine can play a role in some psychiatric conditions, it is not the primary neurotransmitter targeted for its inhibitory effects in anxiety disorders.
Choice C reason: Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the brain, helping to calm neuronal activity and reduce anxiety. Many anti-anxiety medications, such as benzodiazepines, enhance GABA’s effects to promote relaxation and reduce symptoms of anxiety.
Choice D reason: Norepinephrine is an excitatory neurotransmitter associated with the body’s stress response and arousal. Elevated levels are often linked to increased anxiety, so it is not targeted for inhibitory effects in anxiety treatments.

Correct Answer is B
Explanation
Choice A reason:Standing 1 ft away from a verbally abusive client is too close and may escalate the situation by invading their personal space. Maintaining a safe distance (about 3–6 ft) is recommended for safety.
Choice B reason:Speaking slowly in a low, calm voice helps de-escalate the situation by modeling calm behavior and reducing the client’s agitation. This approach promotes a safe environment and encourages de-escalation.
Choice C reason:Forbidding the client from speaking abusively may escalate their agitation, as it can be perceived as confrontational. A non-confrontational approach, like staying calm, is more effective.
Choice D reason:Informing the client of consequences may be appropriate later, but it is not the first action. De-escalation through calm communication is the priority to manage the immediate verbal abuse safely.
