Which nursing diagnosis should be most useful for clients with anxiety disorders for whom the following defining characteristics have been identified: avoidance, poor concentration, nightmares, hypervigilance, exaggerated startle response, detachment, numbing, and flashbacks?

Disturbed Sensory Perception

Anxiety

Post-Trauma Syndrome

Powerlessness

Answer and Explanation

The Correct Answer is C

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

Correct Answer is A

Explanation

Choice A reason: Fine motor tremors are a common early side effect of lithium, affecting cerebellar function due to its narrow therapeutic index and sodium channel interactions. These typically subside within weeks as the body adjusts to stable serum levels (0.5–1.2 mEq/L), making this an accurate, reassuring response.

Choice B reason: Dismissing tremors as unimportant unless persistent for a month is incorrect. Lithium tremors, linked to cerebellar effects, often resolve sooner, but persistent tremors may indicate toxicity (levels >1.5 mEq/L), risking neurological damage. This response delays necessary monitoring, ignoring the drug’s neuropharmacological impact.

Choice C reason: Acknowledging tremors but implying the client’s concern is excessive is dismissive. Tremors result from lithium’s cerebellar effects, a legitimate side effect. This response fails to educate about the expected resolution timeline or need for monitoring, risking patient distrust and ignoring the drug’s neurobiological effects.

Choice D reason: Labeling tremors as a potential toxicity sign is misleading, as early fine tremors are typically benign, not indicative of toxicity (>1.5 mEq/L), which involves severe symptoms like confusion. This overstates risk, causing unnecessary alarm, and does not address the common, transient cerebellar effect of lithium.

A. Derealization B. Hyperarousal C. A flashback D. Emotional numbing

Correct Answer is C

Explanation

Choice A reason: Derealization, a dissociative symptom in PTSD, involves feeling detached from reality, linked to altered prefrontal cortex and limbic system activity. Panic from a similar ICU case suggests a triggered memory, not detachment. Derealization is less likely, as the nurse’s response aligns with reliving a traumatic event, not perceptual distortion.

Choice B reason: Hyperarousal in PTSD involves heightened alertness and exaggerated startle, driven by amygdala hyperactivity and elevated norepinephrine. While panic suggests arousal, the trigger of a similar ICU case points to reliving a specific traumatic memory, making flashback more precise than general hyperarousal, which lacks the event-specific re-experiencing component.

Choice C reason: A flashback in PTSD involves reliving a traumatic event, triggered by cues like a similar ICU case, due to amygdala-driven memory reactivation and hippocampal dysfunction. The nurse’s panic reflects re-experiencing the parent’s death, a hallmark of PTSD, where sensory cues vividly recall trauma, causing intense emotional distress.

Choice D reason: Emotional numbing in PTSD involves reduced emotional responsiveness, linked to prefrontal cortex suppression. Panic from a similar ICU case indicates an active emotional response, not numbing. The nurse’s reaction aligns with re-experiencing trauma via a flashback, driven by amygdala activation, rather than emotional detachment.
