A nurse is caring for a client who is at risk for sensory overload. Which of the following actions should the nurse take?

Sensory overload occurs when excessive environmental stimuli such as noise, light, interruptions, and social interaction overwhelm the central nervous system, leading to agitation, impaired cognition, sleep disturbance, and decreased ability to process information, particularly in vulnerable or hospitalized clients. Rationale: A. Fragmented care delivery increases interruptions and unpredictability, which can worsen sensory overload by preventing rest and creating inconsistent stimulation patterns. Therefore disorganized care scheduling is not appropriate. B. Continuous lighting contributes to visual overstimulation and disrupts circadian rhythm regulation, increasing risk of sleep deprivation and confusion. Thus excessive light exposure exacerbates sensory overload. C. Constant background television noise adds unnecessary auditory stimulation, which can increase confusion and reduce cognitive rest. Therefore persistent auditory input is not therapeutic in sensory overload management. D. Visitor control reduces external stimuli such as conversation, movement, and noise, helping maintain a calm environment. Monitoring and limiting visitors is an effective strategy to prevent worsening of sensory overload symptoms.
