The nurse is providing care for a geriatric patient with loss of hearing acuity over the past several years. Which statement by the nurse is most accurate?

. Shellfish allergies are related to potential reactions to iodinated contrast media used in imaging studies, such as CT scans, rather than to spirometry. Spirometry does not involve contrast media or shellfish, so this question is not pertinent for this test.
B.A Metal implants are typically a concern for imaging tests like MRI, which involve strong magnetic fields. Spirometry, however, does not involve any imaging or use of magnetic fields, so metal implants do not affect spirometry results. Thus, this question is not relevant for spirometry preparation.
C. This is a relevant question for spirometry testing. Bronchodilators are medications used to open the airways and improve breathing. They can affect spirometry results if taken shortly before the test. For accurate assessment, the nurse needs to know if the client has used any bronchodilators, as they might need to adjust the testing protocol or account for the medication's effects on lung function.
D. Spirometry does not typically involve enclosed spaces that would trigger claustrophobia, as it is a breathing test usually performed with the client sitting comfortably in an open space. Claustrophobia is more relevant to imaging studies like MRIs or CT scans, where the client might be in a confined space.

A. Prednisone is a corticosteroid used to reduce inflammation and suppress the immune system. While effective for reducing inflammation and pain, corticosteroids are generally not the first-line treatment for osteoarthritis. They are more commonly used for inflammatory arthritis conditions like rheumatoid arthritis.
B. Etanercept is a biologic agent used to treat autoimmune conditions like rheumatoid arthritis and psoriatic arthritis by targeting tumor necrosis factor-alpha (TNF-alpha) to reduce inflammation. It is not indicated for osteoarthritis, which is a non-inflammatory degenerative joint disease rather than an autoimmune inflammatory disease.
C. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to manage pain and inflammation associated with osteoarthritis. NSAIDs like ibuprofen are often the first-line treatment for osteoarthritis because they help reduce pain and inflammation, improve function, and enhance the quality of life for patients. Ibuprofen is a suitable and preferred option for managing symptoms of osteoarthritis.
D. Hydroxychloroquine is an antimalarial drug that is also used to treat autoimmune diseases such as rheumatoid arthritis and lupus. It works by modulating the immune system and reducing inflammation. However, it is not typically used for osteoarthritis, which is not an autoimmune condition.
