The nurse educator asks the student nurse to explain the most common causes of blindness in the United States. Which of the following options will the student nurse select as one of the top causes of blindness?

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.

Choice A Reason: This is correct because melanoma is a type of skin cancer that arises from melanocytes, which are cells that produce pigment. Melanoma lesions are often irregular in shape and color, and may have different shades of brown or black.

Choice B Reason: This is correct because melanoma is a very aggressive and invasive type of skin cancer that can spread quickly to other parts of the body through the blood or lymphatic system. Melanoma has a high mortality rate if not detected and treated early.

Choice C Reason: This is incorrect because warm and red skin around a lesion may indicate inflammation or infection, but not necessarily melanoma. Melanoma lesions may have other signs, such as bleeding, itching, or ulceration.

Choice D Reason: This is correct because melanoma is associated with exposure to ultraviolet (UV) radiation from sunlight or artificial sources, such as tanning beds. UV radiation can damage the DNA of melanocytes and cause them to grow abnormally.

Choice E Reason: This is incorrect because melanoma lesions are usually not painful unless they are ulcerated or infected. Pain may be a sign of other types of skin conditions, such as burns, blisters, or cuts.
