A nurse is assessing a client who has Lewy body dementia. The nurse should recognize that which of the following is responsible for changes in thinking, communication, movement, and emotional processing in Lewy body dementia?

A. "I notice the ringing when I'm not concentrating on something." This statement suggests that the client notices the tinnitus but does not imply a significant impact on their well-being. It indicates that the tinnitus occurs when the client is not focused on tasks, which may not necessarily affect their overall functioning or well-being.

B. "I am still able to complete my work in a timely manner." This statement indicates that the client can still function adequately in their work despite experiencing tinnitus. While this may suggest some level of coping, it does not directly address the impact of tinnitus on the client's overall well-being.

C. "The ringing in my ears is distracting." This is the correct answer. This statement indicates that the tinnitus is distracting to the client, which suggests that it may affect their concentration, focus, or overall quality of life. The distraction caused by tinnitus can significantly impact daily activities and well-being.

D. "Hopefully a treatment for this ringing in my ears will help." While this statement acknowledges the presence of tinnitus and the desire for treatment, it does not directly address the impact of tinnitus on the client's well-being. It focuses more on the hope for relief through treatment rather than the current impact on their quality of life.

A. Relocation stress syndrome: Relocation stress syndrome refers to the physical and psychological symptoms experienced by individuals when they are moved from one environment to another, such as transitioning to a new residence or healthcare facility. While relocation stress syndrome can cause agitation and confusion in individuals with Alzheimer's disease, the scenario provided does not indicate a recent relocation.

B. Wandering: Wandering is a common behavior observed in individuals with dementia, where they aimlessly roam or wander in their environment. While wandering may be associated with agitation and restlessness, the scenario does not describe the client physically moving around or attempting to leave their home.

C. Sundowning: Sundowning refers to a phenomenon commonly observed in individuals with Alzheimer's disease or other forms of dementia, where they experience increased agitation, confusion, and restlessness in the late afternoon or early evening hours. Sundowning behaviors can include pacing, agitation, anxiety, irritability, confusion, and difficulty sleeping. The exact cause of sundowning is not fully understood but may be related to factors such as fatigue, sensory overload, hormonal imbalances, or disruptions in the sleep-wake cycle. Managing sundowning behaviors often involves creating a calming environment, maintaining a consistent daily routine, minimizing stimuli in the evening, and providing reassurance and comfort to the individual.

D. Depression: Depression can occur in individuals with Alzheimer's disease and may present with symptoms such as sadness, hopelessness, loss of interest in activities, changes in appetite or sleep patterns, and difficulty concentrating. However, the scenario primarily describes agitation and restlessness in the evening hours, which is characteristic of sundowning rather than depression.
