A nurse is caring for a client who has suffered a stroke involving the left hemisphere. Which of the following alterations in function are consistent with this type of stroke?

Choice A reason: This is incorrect because increasing her voice when speaking to the client may not prevent complications, but rather annoy or offend the client. The nurse should not assume that a client with a visual impairment has a hearing impairment as well unless it is confirmed by assessment or history. The nurse should speak in a normal tone and volume and identify herself by name and role.
Choice B reason: This is incorrect because lowering the bed rails before lowering the bed may increase the risk of complications, such as falls or injuries. The nurse should keep the bed rails up until the client is ready to get out of bed and lower them only when necessary. The nurse should also lock the wheels of the bed and adjust it to a comfortable height for the client.
Choice C reason: This is incorrect because using hand gestures to point to where the client will walk may not prevent complications, but rather confuse or frustrate the client. The nurse should not use visual cues or gestures that are meaningless to a client with a visual impairment. The nurse should use verbal directions and descriptions instead, such as "The restroom is on your left, about 10 steps away."
Choice D reason: This is correct because standing slightly in front and to one side of the client can prevent complications, such as collisions or falls. The nurse should guide the client by offering her arm or shoulder for support and walking slightly ahead of him or her. The nurse should also warn the client about any obstacles or changes in terrain, such as stairs, doors, or rugs.

Choice A Reason: This is correct because incorporating foods rich in vitamin C in the diet can help prevent or delay macular degeneration. Vitamin C is an antioxidant that can protect the cells of the macula, which is the central part of the retina that is responsible for sharp and detailed vision, from oxidative stress and damage. The nurse should also advise the client to consume foods rich in other antioxidants, such as vitamin E, zinc, lutein, and zeaxanthin.

Choice B Reason: This is correct because receiving injections into the eye can help treat macular degeneration. Injections are a form of anti-vascular endothelial growth factor (anti-VEGF) therapy, which can block abnormal blood vessel growth and leakage in the macula that can cause vision loss. The nurse should explain to the client how often and how long they need to receive injections and what side effects or complications they may experience.

Choice C Reason: This is incorrect because vision will not be restored after using eye drops for macular degeneration. Eye drops are not a proven or effective treatment for macular degeneration, which is a chronic and progressive condition that causes irreversible vision loss. The nurse should reinforce education by informing the client that eye drops may only provide temporary relief of dryness or irritation, but they will not improve or restore vision.

Choice D Reason: This is correct because vision will become progressively more blurry with macular degeneration. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field. The nurse should educate the client on how to cope with vision loss and use adaptive devices, such as magnifiers, large-print books, or voice-activated technology.
