A nurse is caring for a client who has dementia and became more confused after breakfast. Which of the following environmental factors could be contributing to the increased confusion?

Introduction: Environmental management in dementia care focuses on providing sensory cues and maintaining a circadian rhythm to reduce agitation and prevent the worsening of cognitive impairment known as sundowning. A. Labeling the bathroom with large letters is a positive environmental modification that aids in orientation and promotes independence. This reduces confusion by providing a clear visual cue for the client, helping them navigate their environment without the distress associated with being unable to find necessary facilities. B. Providing limited choices during mealtime is a therapeutic intervention for clients with dementia. Excessive choices can lead to "decisional overload" and increased frustration. By narrowing options, the nurse reduces the cognitive demand on the client, which typically decreases rather than increases confusion or agitation. C. Playing soft classical music in care areas is often used as a therapeutic intervention to create a calm and soothing atmosphere. It can help reduce environmental noise that might be overstimulating. Generally, low-volume, familiar music is beneficial for mood stabilization and reducing anxiety in cognitively impaired individuals. D. Keeping the curtains closed can contribute to confusion by blocking natural light, which is essential for maintaining the client's sleep-wake cycle. For clients with dementia, a lack of environmental cues regarding the time of day can lead to disorientation, increased restlessness, and the exacerbation of confused states
