In the context of seropositive rheumatoid arthritis (RA), the disease presents with several hallmark symptoms. Let's delve into each option to explain why all of them are correct indicators of seropositive RA:
- Multiple joints affected: Rheumatoid arthritis often manifests in numerous joints, especially those of the hands, wrists, and knees. It is a systemic condition that does not limit itself to a single joint.
- Symmetrical joint symptoms: A distinct characteristic of RA is its symmetry. If a joint in one hand is affected, the corresponding joint in the other hand usually is too. This symmetry differentiates RA from other types of arthritis.
- Joint pain and swelling: This condition causes inflammation, leading to pain, warmth, and swelling of the joints. The inflammatory process is a key feature and major cause of discomfort in RA.
- All: Given that all the listed symptoms are characteristic of seropositive RA, the option "All" aptly encompasses the array of symptoms associated with this chronic autoimmune disorder.
Thus, the correct answer is "All," as all the symptoms listed are typical features seen in seropositive rheumatoid arthritis.
