What should the nurse remember about confusion in an elderly client with Alzheimer disease?

The correct choice highlights the significant impact that a change in environment can have on an elderly client with Alzheimer disease. Confusion can often be exacerbated when individuals with cognitive impairment are placed in new surroundings where familiar cues and comfort are absent. This scenario can lead to increased disorientation and anxiety, making it essential for caregivers and healthcare professionals to maintain routines and use familiar items to soothe or reorient the individual during such transitions.

The other options do not accurately reflect the realities of caring for patients with Alzheimer disease. While confusion can occur as part of normal aging, it is not specifically a common or expected finding in the context of Alzheimer's, which is a neurodegenerative disease with distinct differences from typical age-related cognitive decline. Additionally, reality orientation strategies can sometimes help, albeit with limited efficacy, thus this response does not stand alone as immutable when considering each patient’s condition. Lastly, it is incorrect to suggest that interventions are futile; while they may be challenging, various strategies can still provide support and improve quality of life for those affected by Alzheimer disease.
