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. Comply with compression therapy: Compression therapy is commonly used in the management of peripheral vascular disease (PVD), not valvular heart disease. It involves applying external pressure to the limbs to improve circulation and reduce edema. While this intervention may be relevant for a client with PVD, it is not specific to valvular heart disease.

B. Monitor wounds on lower extremities: Monitoring wounds on lower extremities is important for clients with peripheral vascular disease (PVD) to assess for signs of poor wound healing, infection, or tissue ischemia. However, it is not directly related to valvular heart disease. Therefore, while wound monitoring may be appropriate for this client, it is not specific to valvular heart disease education.

C. Take antiplatelet medications as ordered: Antiplatelet medications, such as aspirin or clopidogrel, are commonly prescribed for clients with peripheral vascular disease (PVD) to reduce the risk of thrombotic events and improve blood flow. However, they are not typically indicated as a primary treatment for valvular heart disease. While some clients with valvular heart disease may have comorbidities that warrant antiplatelet therapy, it is not specific to valvular heart disease education.

D. Valvular heart disease involves dysfunction of one or more heart valves, leading to impaired blood flow within the heart. The nurse should educate the client on monitoring for the gradual onset of symptoms related to valvular heart disease. These symptoms may include dyspnea (shortness of breath), fatigue, palpitations, chest discomfort, and edema. Monitoring for these symptoms allows for early detection of disease progression or exacerbation, prompting timely intervention and management.

A. "I can't see anything from the sides of my eyes." This statement suggests a visual field deficit, which may be indicative of conditions affecting peripheral vision, such as glaucoma, retinal detachment, or optic nerve disorders. It is not a typical symptom of cataracts.

B. "My vision is almost gone from the center part of my eye." This statement indicates a central visual impairment, which is a common symptom of cataracts. Cataracts cause clouding of the lens, leading to blurred or dimmed vision, especially in the center of the visual field. This symptom often progresses gradually over time.

C. "My contact lenses just don't fit like they used to." This statement suggests discomfort or fit issues with contact lenses and is not specifically indicative of cataracts. It may be related to changes in the shape or health of the cornea, conjunctiva, or tear film.

D. "I keep seeing flashes of lights moving around in my eye." Flashes of light in the visual field are not typical symptoms of cataracts. They may indicate other ocular conditions such as vitreous detachment, migraines with aura, or retinal disorders.
