Choice C reason: RA can affect multiple body systems beyond the joints, including the cardiovascular and respiratory systems, so it is essential to monitor all body systems.

Choice D reason: Exercise is actually beneficial for patients with RA to maintain joint function and muscle strength; rest is important, but should be balanced with physical activity.
