Crepitus with joint movement is correct. Crepitus, a grating sound, is an expected finding of osteoarthritis as loosened bone and cartilage move in the diseased joint.

Decreased range of motion of the affected joint is correct. Decreased range of motion is an expected finding of osteoarthritis because the client's pain limits movement.

Low-grade fever is incorrect. Osteoarthritis does not cause systemic manifestations. Rheumatoid arthritis causes many systemic manifestations, including low-grade fever, weakness, anorexia, and paresthesias.

Spongy tissue over the joints is incorrect. Spongy joint tissue is an expected finding of rheumatoid arthritis, which is an inflammatory disease.

Joint pain that resolves with rest is correct. Clients who have osteoarthritis have increased pain with activity and decreased pain with rest.
