What systemic symptoms should a nurse look for when assessing a client with rheumatoid arthritis?

When assessing a client with rheumatoid arthritis, systemic symptoms such as loss of appetite and weight loss are particularly significant. Rheumatoid arthritis is an autoimmune condition characterized not only by joint inflammation but also by systemic effects that can lead to a decline in overall health. The inflammatory process involved in rheumatoid arthritis can trigger a response from the body that results in symptoms like decreased appetite and unintended weight loss. These manifestations occur as the body diverts energy and resources to combat the autoimmune attack on the joints, which can affect metabolic processes and appetite regulation.

In contrast, increased joint mobility is typically not associated with rheumatoid arthritis; rather, stiffness and reduced mobility due to inflammation and pain are more common. Localized swelling in joints and redness and warmth are indeed important signs of arthritis but are considered more localized rather than systemic symptoms. They indicate inflammatory activity in specific joints rather than the systemic implications of the disease. Hence, the emphasis on systemic symptoms, like weight loss and appetite changes, highlights the broader impact of rheumatoid arthritis on a patient's health beyond just the joints.
