A nurse is caring for a client who reports a decrease in central vision. The nurse should identify that this is a manifestation of which of the following visual impairments?
Macular degeneration
Glaucoma
Diabetic retinopathy
Cataract
The Correct Answer is A
Choice A Reason: This is correct because macular degeneration is a condition that affects the macula, which is the central part of the retina that is responsible for sharp and detailed vision. Macular degeneration can cause blurred or distorted central vision, difficulty reading or recognizing faces, or dark spots in the visual field.
Choice B Reason: This is incorrect because glaucoma is a condition that affects the optic nerve, which is the nerve that connects the eye to the brain and carries visual signals. Glaucoma can cause increased pressure inside the eye, damage to the optic nerve, and loss of peripheral vision.
Choice C Reason: This is incorrect because diabetic retinopathy is a condition that affects the blood vessels in the retina, which is the layer of tissue at the back of the eye that converts light into nerve impulses. Diabetic retinopathy can cause bleeding, swelling, or leakage of fluid in the retina, and loss of vision in any part of the visual field.
Choice D Reason: This is incorrect because cataract is a condition that affects the lens, which is the transparent structure behind the pupil that focuses light onto the retina. Cataract can cause clouding or opacity of the lens, and reduced vision in all parts of the visual field.

Correct Answer is C
Explanation
Choice A Reason: This is incorrect because drawing with crayons may be too childish or frustrating for a client with moderate Alzheimer's. Crayons may also pose a choking hazard or cause messes. The nurse should provide activities that are suitable for the client's cognitive and functional level, as well as their interests and preferences.
Choice B Reason: This is incorrect because dangling ribbons or a mobile may be too stimulating or confusing for a client with moderate Alzheimer's. These items may also trigger agitation or wandering behaviors. The nurse should provide activities that are calming and familiar for the client.
Choice C Reason: This is correct because listening to music, watching TV, or videos can be enjoyable and beneficial for a client with moderate Alzheimer's. Music can evoke memories, emotions, and positive responses. TV or videos can provide entertainment, education, and socialization. The nurse should choose music, TV shows, or videos that are appropriate and meaningful for the client.
Choice D Reason: This is incorrect because board games may be too complex or challenging for a client with moderate Alzheimer's. Board games may require memory, concentration, logic, or strategy skills that the client may have lost. The nurse should provide activities that are simple and easy for the client to follow.
Correct Answer is C
Explanation
Choice A Reason: Obtaining the client's blood glucose every 12 hr is not enough, as the nurse should monitor it more frequently, at least every 4 to 6 hr, to prevent hyperglycemia or hypoglycemia. TPN is a high-glucose solution that can affect the blood sugar levels.
Choice B Reason: Changing the IV site dressing every 4 days is not enough, as the nurse should change it daily or as needed to prevent infection. TPN is a high-risk solution that can introduce microorganisms into the bloodstream.
Choice C Reason: This is the correct choice. Changing the IV tubing every 24 hr is recommended to prevent infection and maintain sterility. TPN is a complex solution that can support bacterial growth and contamination.
Choice D Reason: Weighing the client every other day is not enough, as the nurse should weigh the client daily to evaluate fluid balance and nutritional status. TPN can cause fluid retention or depletion, as well as weight gain or loss.
