Luis, a nursing student, is explaining to his patient the mechanism of action of selective serotonin reuptake inhibitors (SSRIs). What should he include?
SSRIs increase norepinephrine levels to elevate mood.
SSRIs inhibit serotonin production in the brain.
SSRIs decrease dopamine levels to improve mood.
SSRIs increase serotonin levels by preventing its reuptake into neurons.
The Correct Answer is D
Choice A reason: SSRIs do not increase norepinephrine levels; that is the action of SNRIs or other antidepressant classes.
Choice B reason: SSRIs do not inhibit serotonin production; instead, they work by blocking reuptake, leading to increased serotonin availability.
Choice C reason: SSRIs do not lower dopamine levels; this would worsen mood symptoms rather than improve them.
Choice D reason: SSRIs block serotonin reuptake in presynaptic neurons, which increases serotonin availability in the synaptic cleft and helps elevate mood.

Explanation
Choice A reason: Antianxiety medications do not protect the liver from alcohol; in fact, both can increase liver strain, especially with long-term use.
Choice B reason: Alcohol does not simply negate the effects but instead potentiates sedation, worsening impairment.
Choice C reason: Increased alertness is the opposite of what occurs; both substances are central nervous system depressants.
Choice D reason: The interaction between alcohol and antianxiety medications intensifies sedation, impairs coordination, and can suppress breathing, making it dangerous and potentially life-threatening.
Correct Answer is A
Explanation
Choice A reason: This reflects an internal crisis of denial, where the client struggles to accept the diagnosis and cope with the emotional impact, leading to rejection of treatment.
Choice B reason: A situational crisis is triggered by external life events like loss of a job or sudden illness in a family member, not by denial of a personal diagnosis.
Choice C reason: A maturational crisis occurs during developmental transitions like adolescence or retirement, which is unrelated to this scenario.
Choice D reason: An adventitious crisis is caused by unexpected disasters such as natural catastrophes or acts of violence, not a medical diagnosis.
