A female client presents to the orthopedic clinic for evaluation. The primary care provider told her she has a "spur" on her joint. She asks, "Why did this happen? I guess I just didn't exercise enough."
The nurse recognizes this to be a later structural change of osteoarthritis (OA), where the client no longer has a "shock absorber," culminating in:
A) Osteonecrosis and loss of synovial fluid
B) Formation of tophi in the synovial space
C) Osteophyte formation and erosion of cartilage
D) Separation of the epiphyseal plate
Ans: C
Feedback:
As OA progresses, cartilage is lost and osteophytes, or spurs, develop on the surface of the articulating bones. Osteonecrosis does not typically develop, and synovial fluid is not lost. Tophi are associated with gout, not OA, and the epiphyseal plate does not separate in the course of OA.
