A client with rheumatoid arthritis has an elevated serum rheumatoid factor. Which interpretation of this finding should the nurse make?

Choice A reason: Corticosteroid cream was applied to eczema is not a useful information in determining the possible cause of the symptoms, because it is a treatment that can reduce the inflammation and itching of eczema, not a trigger that can worsen it. Corticosteroid cream should be used as prescribed by the doctor, and the nurse should instruct the client on how to apply it correctly and safely.

Choice B reason: A grandson and his new dog recently visited is a useful information in determining the possible cause of the symptoms, because it can indicate that the client was exposed to an allergen or an irritant that can trigger an eczema flare-up. Some people with eczema may have allergic reactions to animal dander, saliva, or fur, which can cause skin inflammation, redness, and itching. The nurse should ask the client about their history of allergies and their contact with the dog, and advise them to avoid or minimize exposure to potential allergens.

Choice C reason: An old friend with eczema came for a visit is not a useful information in determining the possible cause of the symptoms, because eczema is not a contagious condition that can be transmitted from person to person. Eczema is a chronic skin disorder that causes dry, itchy, and inflamed skin, and it is influenced by genetic, environmental, and immune factors. The nurse should reassure the client that eczema is not infectious and that they can maintain social relationships with other people with eczema.

Choice D reason: Recently received an influenza immunization is not a useful information in determining the possible cause of the symptoms, because there is no evidence that influenza immunization can cause or worsen eczema. Influenza immunization is a preventive measure that can protect the client from getting the flu, which can be a serious and sometimes fatal illness, especially for people with chronic conditions, such as eczema. The nurse should encourage the client to get vaccinated for influenza and other diseases, as recommended by the doctor.

Choice A reason: A husky voice and complaints of hoarseness are not related to Cushing's syndrome, but may indicate a thyroid disorder or vocal cord damage.

Choice B reason: Warm, soft, moist, salmon-colored skin is not a characteristic of Cushing's syndrome, but may be seen in hyperthyroidism or infection.

Choice C reason: Visible swelling of the neck, with no pain, is not a sign of Cushing's syndrome, but may indicate a goiter or thyroid enlargement.

Choice D reason: Central-type obesity, with thin extremities, is a common feature of Cushing's syndrome, which is caused by excess cortisol production or exposure. Cortisol causes fat redistribution to the trunk, face, and back of the neck, while causing muscle wasting and weakness in the arms and legs.
