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: Drooling is not a common side effect of amitriptyline; instead, dry mouth due to anticholinergic effects is more likely.
Choice B reason: Orthostatic hypotension is a well-documented adverse effect of amitriptyline, related to its action on the autonomic nervous system. Nurses should closely monitor for dizziness, falls, or fainting.
Choice C reason: Diarrhea is not a typical adverse effect of amitriptyline; constipation is more commonly seen because of anticholinergic properties.
Choice D reason: Metallic taste in the mouth is not a notable adverse effect of amitriptyline and is more often associated with other medications such as certain antibiotics.
Correct Answer is A
Explanation
Choice A reason:Major depressive disorder carries a high risk of suicide, especially in acute settings. Monitoring for self-harm is the priority to ensure the client’s safety, as it addresses an immediate, life-threatening risk before other interventions.
Choice B reason:Administering antidepressants is important for managing depression, but it is not the priority over safety. Antidepressants take weeks to become effective, and the risk of self-harm must be addressed first.
Choice C reason:Assisting with activities of daily living supports the client’s functional needs, but it is not the priority. Safety concerns, such as self-harm risk, take precedence in acute depression.
Choice D reason:Encouraging fluid intake is important for physical health, but it is not the priority in major depressive disorder. Preventing self-harm is critical due to the high risk of suicide in this condition.
