A nurse is caring for a client who has shortness of breath and a chronic cough. The client has smoked one pack of cigarettes per day for the last 20 years. Which finding on the client's chest x-ray would be consistent with a diagnosis of advanced COPD?

A. Floaters and flashes of light are classic symptoms of retinal detachment. When the retina begins to detach from the underlying tissue, it can cause these visual disturbances. Floaters are small, shadowy shapes that move across the field of vision, while flashes of light can occur due to the retina being stretched or pulled.
B. Cataracts primarily cause blurred vision, difficulty seeing at night, and sensitivity to light, rather than floaters or flashes of light.
C. AMD generally affects central vision and can cause symptoms such as distorted vision, difficulty seeing in low light, and a loss of central vision. While AMD can cause vision changes, it is not typically associated with seeing floaters and flashes of light.
D. Open-angle glaucoma usually progresses slowly and is often asymptomatic in its early stages. It primarily affects peripheral vision, leading to a gradual loss of vision in the periphery.

. 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.
