Final answer:
Sarcoidosis most commonly occurs in African American women, although it can affect any ethnic group. It is an inflammatory disease that can affect multiple organs, predominantly the lungs and lymph glands.
Step-by-step explanation:
The client's concern about the occurrence of sarcoidosis in relation to ethnicity is a valid question. When educating a client who has been recently diagnosed with sarcoidosis, it is important for the registered nurse (RN) to provide information about the demographics of the disease. Sarcoidosis is an inflammatory disease that affects multiple organs in the body, but mostly the lungs and lymph glands. In terms of prevalence by ethnicity, the disease most commonly occurs in African American women. This group has a higher incidence of sarcoidosis than Caucasian, Asian, or Hispanic women. However, it's crucial to remember that sarcoidosis can affect individuals of any ethnic background, and the exact cause of the disease is still unknown. Hereditary and environmental factors may contribute to a person's susceptibility to developing sarcoidosis.
