Which term describes inflammation of one or more joints?

• A. Inflammation of a tendon sheath
• B. Degenerative Joint Disease
• C. Inflammation of one or more joints
• D. Infection of a Joint

Answer: (C)

The concept being tested is what term describes inflammation of joints. Arthritis is defined as inflammation of one or more joints, so the option that states inflammation of one or more joints matches exactly what arthritis means. This makes it the best choice because it directly expresses the defining feature of the condition.

Think of the other terms as describing different problems: inflammation of a tendon sheath is tenosynovitis, which involves tendons rather than the joints themselves. Degenerative Joint Disease refers to osteoarthritis, a degenerative process that can involve inflammation but is not defined by joint inflammation alone. Infection of a joint is septic arthritis, a joint infection with a distinct cause and treatment.
