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.

Correct Answer is D
Explanation
Choice A reason:Requiring definitive evidence before reporting suspected child abuse is incorrect. Healthcare professionals are mandated to report suspicion of abuse, as investigations determine the validity, not the reporter.
Choice B reason:A commitment from the abuser to stop does not exempt healthcare workers from reporting. Suspected abuse must be reported to protect the child, regardless of promises made by the potential abuser.
Choice C reason:Concern about defamation is understandable but does not override the duty to report suspected abuse. Mandatory reporting laws prioritize child safety and provide legal protection for reporters acting in good faith.
Choice D reason:Mandatory reporting laws require healthcare workers to report any suspicion of child abuse, even without confirmed evidence. This statement reflects an accurate understanding of the legal and ethical obligation to prioritize child safety.
Correct Answer is B
Explanation
Choice A reason: Delayed menarche at age 13 is within normal developmental variation. Although it may cause concern for the adolescent, it is not an immediate priority unless accompanied by other signs of delayed puberty.
Choice B reason: Expressing social isolation and rejection is a priority because it may indicate depression or risk for self-harm. Adolescents who feel excluded and disliked are more vulnerable to mental health crises.
Choice C reason: Perceiving parents as overprotective is common in adolescence as teenagers seek independence. This is not typically a clinical concern.
Choice D reason: Concerns about acne and appearance are common during adolescence and usually reflect normal developmental self-consciousness rather than a safety issue.
