A nurse is discussing the difference between rheumatoid arthritis (RA) and osteoarthritis with a newly hired nurse. Which of the following information should the nurse include about osteoarthritis?
"Osteoarthritis causes the joints to become red and hot."
"Osteoarthritis is caused by an autoimmune process."
"Osteoarthritis affects other organs in the body."
"Osteoarthritis can impair a joint on a single side of the body."
The Correct Answer is D
A. "Osteoarthritis causes the joints to become red and hot." This is more characteristic of rheumatoid arthritis, which involves inflammation leading to redness and warmth. Osteoarthritis typically causes pain and stiffness without significant redness or heat.
B. "Osteoarthritis is caused by an autoimmune process." Rheumatoid arthritis is an autoimmune disease where the body's immune system attacks its own tissues. Osteoarthritis is a degenerative joint disease caused by wear and tear of the cartilage.
C. "Osteoarthritis affects other organs in the body." Rheumatoid arthritis is a systemic condition that can affect multiple organs. Osteoarthritis is localized to the joints and does not affect other organs.
D. "Osteoarthritis can impair a joint on a single side of the body." Osteoarthritis can affect one joint or joints on one side of the body, such as one knee or one hip, whereas rheumatoid arthritis typically affects joints symmetrically.

Correct Answer is B
Explanation
