A client diagnosed with contact dermatitis is receiving education from the nurse. Which of the following therapies will the nurse recommend to the client?

Choice A Reason: The test does not assess for sun protection factor, but rather for contact dermatitis. Sun protection factor is a measure of how well a sunscreen protects the skin from ultraviolet radiation, which can cause sunburn and skin damage.

Choice B Reason: The test is not inconclusive, but rather positive for some allergens and negative for others. The test involves applying small patches of different substances to the skin and observing for any reactions after 48 hours.

Choice C Reason: This is the correct choice. The presence of erythema indicates you are allergic to the allergen, as it shows inflammation and irritation of the skin due to an immune response. Erythema is redness of the skin that can be accompanied by itching, swelling, or blisters.

Choice D Reason: The areas that did not turn red do not indicate low risk for skin cancer, but rather no reaction to the allergen. Skin cancer is a malignant growth of abnormal cells in the skin that can be caused by various factors, such as genetic mutations, exposure to carcinogens, or immunosuppression.

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.
