Final answer:
Polyarteritis nodosa (PAN) is an autoimmune disease that causes inflammation in various organs. Additional tests may include organ biopsies and blood tests to assess inflammation levels. Treatment typically involves medications to control inflammation and suppress the immune system.
Step-by-step explanation:
Polyarteritis nodosa (PAN) is a rare autoimmune disease that primarily affects the small and medium-sized arteries. The nurse should inform the client that PAN can cause inflammation in various organs, such as the skin, kidneys, nerves, and gastrointestinal system. In terms of additional tests, the doctor may recommend a biopsy of an affected organ, such as the skin or kidney, to confirm the diagnosis. Additionally, blood tests, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), may be done to assess the levels of inflammation in the body.
As for treatment, the doctor will likely prescribe medications to control inflammation and suppress the immune system. This may include corticosteroids, such as prednisone, and other immunosuppressive drugs, such as cyclophosphamide or methotrexate. The specific treatment plan will depend on the severity of the disease and the organs affected.
