Which nursing intervention best supports a client experiencing sundowning?

Choice A reason: Frequent and firm reorientation can often backfire in patients with dementia or delirium, leading to increased agitation, frustration, and combativeness. When a patient's cognitive processing is impaired, being told they are "wrong" about their reality can feel threatening. A more effective approach is validation therapy or gentle redirection, which minimizes stress and preserves the patient's dignity and calm. Choice B reason: Increasing stimulation is contraindicated for sundowning, as sensory overload is a primary trigger for the confusion and agitation that occurs in the late afternoon and evening. High levels of noise, multiple visitors, or heavy activity can overwhelm the patient's diminished cognitive reserves. The goal should be to simplify the environment and reduce demands on the patient's focus during these hours. Choice C reason: Turning off the lights can actually worsen sundowning symptoms. Dim lighting or shadows can lead to visual misperceptions and illusions, increasing the patient's fear and disorientation. Shadows in a dark room might be perceived as intruders or threatening figures (misinterpretation of sensory input). Keeping the environment well-lit during the late afternoon helps maintain orientation to the surroundings. Choice D reason: Sundowning is best managed by minimizing environmental triggers. A well-lit room prevents the development of frightening shadows, while a calm atmosphere reduces the risk of sensory overstimulation. Maintaining a strict, predictable routine provides the patient with a sense of security and reduces the cognitive load required to navigate the day, which helps mitigate the end-of-day fatigue associated with sundowning.
