Which of the following statements by the caregiver of a client newly diagnosed with dementia requires further intervention by the nurse?

Choice A reason: Monitoring vital signs is critical in withdrawal delirium, as it is a medical emergency involving autonomic hyperactivity from alcohol or drug cessation. Dehydration and electrolyte imbalances elevate heart rate and blood pressure, risking seizures or cardiovascular collapse. Regular monitoring detects instability early, guiding fluid replacement and medication to stabilize cerebral and systemic function.

Choice B reason: Keeping the room dark may reduce sensory overload in withdrawal delirium, but it does not address physiologic instability like dehydration or autonomic hyperactivity. Darkness may calm agitation but risks disorientation in a confused patient, as visual cues aid reality testing. This choice is less critical than monitoring vital signs for ensuring systemic stability.

Choice C reason: Withholding oral fluids is contraindicated in withdrawal delirium, as dehydration exacerbates symptoms like confusion and autonomic instability. Fluid loss from sweating or vomiting, common in withdrawal, disrupts electrolyte balance and cerebral perfusion. Providing fluids corrects hypovolemia, making this choice scientifically inappropriate for maintaining physiologic stability in this critical condition.

Choice D reason: Applying ice to the tongue may reduce swelling from trauma, but it does not address the systemic instability of withdrawal delirium, such as dehydration or autonomic hyperactivity. Tongue swelling is a secondary issue compared to life-threatening risks like seizures or arrhythmias, which require monitoring vital signs and fluid management for stabilization.

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.
