Juan is reviewing the effects of neurotransmitter imbalances in mental health disorders. A decrease in which neurotransmitter is most commonly associated with depression?
Serotonin.
Histamine.
Glutamate.
Norepinephrine.
The Correct Answer is A
Choice A reason: Reduced serotonin levels are strongly associated with depression, as serotonin regulates mood, sleep, and emotional stability. Many antidepressants, such as SSRIs, work by increasing serotonin availability in the brain, supporting its role in depression.
Choice B reason: Histamine is primarily involved in immune responses, wakefulness, and allergic reactions, not mood regulation. It is not commonly linked to depression, making it an incorrect choice.
Choice C reason: Glutamate is an excitatory neurotransmitter involved in learning and memory. While imbalances may play a role in some psychiatric conditions, it is not the primary neurotransmitter associated with depression.
Choice D reason: Norepinephrine is involved in arousal and stress responses, and its dysregulation can contribute to depression. However, serotonin is more consistently and prominently linked to the pathophysiology of depression, making it the better choice.

Correct Answer is A
Explanation
Choice A reason:Recognizing situations that trigger anxiety is a key strategy in managing chronic anxiety. By identifying these triggers, the client can develop coping mechanisms, such as relaxation techniques or cognitive-behavioral strategies, to reduce the impact of anxiety and prevent escalation.
Choice B reason:Completely eliminating stress and anxiety from daily life is unrealistic, as stress is a normal part of life. Instead, the focus should be on managing anxiety through coping strategies, therapy, or medication, rather than expecting to eliminate it entirely.
Choice C reason:While contacting a crisis counselor may be helpful in acute situations, routine weekly contact is not typically part of a discharge plan for chronic anxiety unless specified for ongoing therapy. The focus should be on self-management and regular follow-up with a mental health provider.
Choice D reason:Repressing feelings of anxiety is counterproductive and can worsen symptoms over time. Effective anxiety management involves acknowledging and processing emotions, often through techniques like mindfulness or therapy, rather than suppressing them.
Correct Answer is A
Explanation
Choice A reason: Administering 300 mg three times daily equals 900 mg total (300 mg × 3 = 900 mg).
Choice B reason: 300 mg represents only one dose, not the total for 24 hours.
Choice C reason: 1200 mg would be 300 mg four times daily, which is more than prescribed.
Choice D reason: 600 mg equals 300 mg twice daily, not the correct order.
