A nurse is planning care for an adolescent who is being admitted to an acute care unit following a suicide attempt. Which of the following interventions should the nurse identify as the priority?

Choice A reason: Disturbed Sensory Perception involves altered sensory processing, like hallucinations, not specific to anxiety disorders with flashbacks or hypervigilance. These symptoms stem from heightened amygdala activity and dysregulated cortisol in trauma-related disorders, not sensory distortion. This diagnosis is less precise, as it does not capture the trauma-specific psychological and autonomic responses observed.

Choice B reason: Anxiety is a broad diagnosis encompassing excessive worry and autonomic arousal, but it is less specific than Post-Trauma Syndrome for symptoms like flashbacks and numbing. These indicate a trauma-related disorder, likely PTSD, driven by amygdala hyperactivation and HPA axis dysregulation, requiring a diagnosis that addresses the traumatic etiology and specific symptoms.

Choice C reason: Post-Trauma Syndrome, aligned with PTSD, is the most appropriate diagnosis for symptoms like flashbacks, hypervigilance, and numbing, which result from trauma-induced changes in the amygdala, hippocampus, and prefrontal cortex. These cause intrusive memories, heightened arousal, and emotional detachment, accurately reflecting the neurobiological impact of trauma on stress response systems.

Choice D reason: Powerlessness reflects perceived lack of control, not specific to flashbacks or hypervigilance. While trauma can cause feelings of helplessness, the defining symptoms here involve trauma-specific neurological changes, like amygdala hyperactivity, better captured by Post-Trauma Syndrome. Powerlessness is secondary and l

Choice A reason: Valproic acid does not typically require thyroid function tests, as it primarily affects liver metabolism via glucuronidation and mitochondrial pathways. Thyroid dysfunction is not a common side effect, unlike with lithium, which impacts thyroid hormone synthesis. This instruction is irrelevant, as valproic acid’s toxicity risks are hepatic, not thyroid-related.

Choice B reason: Expecting a gradual decrease in valproic acid dosage is incorrect, as it is titrated to therapeutic levels for conditions like seizures or bipolar disorder, based on serum levels (50–100 mcg/mL). Dosage adjustments depend on efficacy, not routine reduction, as stable neural excitability is needed, making this scientifically inaccurate.

Choice C reason: Taking aspirin for pain with valproic acid is risky, as both inhibit platelet function, increasing bleeding risk via synergistic effects on prostaglandin synthesis. Valproic acid’s hepatic metabolism also raises hepatotoxicity concerns, making aspirin inappropriate. Alternative analgesics like acetaminophen are safer, rendering this instruction incorrect.

Choice D reason: Valproic acid requires regular liver function monitoring, as it is hepatically metabolized and can cause hepatotoxicity, particularly in the first 6 months, due to mitochondrial dysfunction and oxidative stress. Elevated liver enzymes or rare fulminant hepatitis necessitate early detection to prevent liver failure, making this a critical instruction.
