The caregiver of a client with Alzheimer's disease reports to the nurse that often the client will suddenly become angry during meals and nothing seems to calm him down. The nurse teaches the caregiver to use distraction techniques. Which response would be best to teach as an example of this technique?

Choice A reason: Phenytoin, an anticonvulsant, is not routinely given before ECT, as the procedure induces controlled seizures to stimulate brain activity, treating depression via neurochemical changes. Administering phenytoin would inhibit seizure activity, reducing ECT efficacy by blocking neuronal excitability, making this an inappropriate action for the procedure.

Choice B reason: Instructing about post-ECT headaches is valid, as they result from cerebral vasoconstriction or muscle tension during seizures. However, this is a post-procedure expectation, not a priority action during planning. Monitoring cardiac rhythm takes precedence, as ECT’s autonomic stimulation poses immediate cardiovascular risks requiring real-time management.

Choice C reason: Monitoring cardiac rhythm during ECT is critical, as the procedure induces seizures that stimulate the autonomic nervous system, causing transient tachycardia or arrhythmias due to catecholamine surges. These can exacerbate underlying cardiac conditions, risking instability. Continuous monitoring ensures early detection and management of cardiovascular complications, prioritizing patient safety.

Choice D reason: Four-point restraints are not used in ECT, as patients are under general anesthesia, preventing movement. Restraints risk injury and are unnecessary, as muscle relaxants like succinylcholine minimize convulsive movements. This approach contradicts ECT’s controlled, anesthetized protocol, making it inappropriate for ensuring safety during the procedure.

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.
