The nurse is providing care for a client with a recent transverse colostomy. Which observation requires immediate notification of the primary health care provider?

Choice A Reason: This is incorrect because phototherapy is not a recommended therapy for contact dermatitis. Phototherapy involves exposing the skin to artificial light sources that emit specific wavelengths of light that can have anti-inflammatory or immunomodulatory effects. Phototherapy can be used for some skin conditions, such as psoriasis or eczema, but not for contact dermatitis.

Choice B Reason: This is incorrect because antibiotics are not a recommended therapy for contact dermatitis. Antibiotics are drugs that kill or inhibit bacteria that cause infections. Contact dermatitis is not an infection, but an allergic or irritant reaction to a substance that comes in contact with the skin. Antibiotics have no effect on contact dermatitis and may cause adverse effects or resistance.

Choice C Reason: This is incorrect because UV light is not a recommended therapy for contact dermatitis. UV light refers to ultraviolet radiation from sunlight or artificial sources that can damage DNA and cause skin cancer or aging. UV light can also worsen contact dermatitis by increasing inflammation and sensitivity to allergens or irritants.

Choice D Reason: This is correct because avoidance is the best therapy for contact dermatitis. Avoidance means identifying and avoiding the substance that causes the skin reaction. This can prevent further exposure and allow the skin to heal. The nurse can help the client by providing education on how to read labels, use protective clothing or gloves, or substitute safer products.

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.
