An elderly patient with dementia is suspected of being abused by their caregiver. Which sign should alert the nurse to confirm this suspicion?

Choice A reason: Sudden behavioral changes, like agitation or withdrawal, in dementia patients can indicate abuse. These reflect stress responses, with increased cortisol and amygdala activity disrupting cognitive and emotional regulation. Scientifically, such changes signal potential trauma or fear, requiring investigation to confirm abuse and protect the patient’s psychological and physical well-being. Choice B reason: A well-kept appearance doesn’t rule out abuse, as abusers may maintain the patient’s hygiene to conceal mistreatment. Scientifically, abuse can occur without visible neglect, as psychological or physical harm may not affect outward appearance. This sign is unreliable for confirming abuse in dementia patients, as it lacks specificity. Choice C reason: An attentive caregiver may seem positive but can mask controlling or abusive behavior. Scientifically, constant presence could indicate coercive control, not care, potentially increasing the patient’s stress response. This sign is ambiguous, as it doesn’t directly correlate with abuse, requiring further assessment to confirm suspicion in dementia patients. Choice D reason: Expressing gratitude may reflect fear or manipulation rather than genuine sentiment, especially in dementia, where cognitive impairment affects judgment. Scientifically, abuse can induce learned helplessness, prompting positive statements to avoid harm. This sign is unreliable for confirming abuse, as it may mask underlying psychological trauma.
