ATI Pathophysiology Practice Exam

Rheumatoid arthritis is a common autoimmune disorder characterized by the immune system mistakenly attacking the synovial joints, leading to inflammation, pain, and stiffness. This condition can also affect other systems in the body and is known to lead to joint deformities over time. The pathophysiology involves an interplay of genetic, environmental, hormonal, and immune factors that alter the body's normal response, resulting in chronic inflammation and joint destruction.

In contrast, osteoporosis is primarily a metabolic bone disease characterized by decreased bone density and increased fracture risk, rather than an autoimmune process. Hypertension is a complex condition often influenced by lifestyle factors and does not involve the immune system attacking body tissue. Diabetes insipidus is related to a deficiency in vasopressin (antidiuretic hormone), affecting water balance, and is not classified as an autoimmune disorder.
