A client arrives to the clinic with reports of progressive weakness in his lower extremities. Which of the following findings in the client's history is consistent with the client developing Guillain-Barre syndrome?

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.

Choice A reason: This is the correct answer because the Amsler grid test is performed to diagnose macular degeneration. The Amsler grid is a pattern of straight lines with a dot in the center. The client is asked to look at the dot and report any distortions or missing areas in the grid. This can indicate damage to the macula, which is the central part of the retina that provides sharp vision.

Choice B reason: This is incorrect because the Snellen chart test is not performed to diagnose macular degeneration. The Snellen chart is a chart of letters of different sizes that are read from a distance. The client is asked to read the smallest line they can see clearly. This can indicate visual acuity or sharpness of vision, but not macular degeneration.

Choice C reason: This is incorrect because the intraocular pressure test is not performed to diagnose macular degeneration. The intraocular pressure test measures the pressure inside the eye using a device called a tonometer. The client may feel a puff of air or a gentle touch on their eye. This can indicate glaucoma, which is a condition where increased pressure damages the optic nerve, but not macular degeneration.

Choice D reason: This is incorrect because the refraction test is not performed to diagnose macular degeneration. The refraction test measures how well the eye bends light rays using a device called a phoropter. The client looks through different lenses and reports which ones make their vision clearer. This can indicate refractive errors such as nearsightedness, farsightedness, or astigmatism, but not macular degeneration.
