A nurse is caring for a client who has Alzheimer's disease and is experiencing sundown syndrome with anxiety. Which of the following actions should the nurse take?

Choice A reason: Frequently questioning the client about orientation can increase anxiety and agitation, especially in individuals with Alzheimer’s disease. Sundown syndrome already heightens confusion and distress in the evening hours, and repeated questioning may feel overwhelming or frustrating. This approach does not reduce symptoms and can worsen behavioral disturbances. Choice B reason: Providing a low-stimulation environment is the most effective intervention for sundown syndrome. Clients with Alzheimer’s disease are highly sensitive to environmental stimuli, and excessive noise, bright lights, or multiple activities can exacerbate anxiety and agitation. A calm, quiet environment helps reduce sensory overload, promotes relaxation, and decreases the likelihood of behavioral escalation. This makes it the correct answer. Choice C reason: Offering multiple activities to choose from may overwhelm the client. Individuals with Alzheimer’s disease often struggle with decision-making and processing multiple options. Instead of reducing anxiety, this intervention could increase confusion and agitation, particularly during sundown syndrome episodes. Choice D reason: Providing consistency in the client’s routine is generally beneficial for Alzheimer’s disease management, as it reduces confusion and promotes security. However, in the context of sundown syndrome with acute anxiety, the immediate priority is to reduce environmental stimulation. While routine consistency is important long-term, it does not directly address the acute episode as effectively as a low-stimulation environment.
