Choice A rationale:

Encouraging the client to avoid using affected joints as much as possible can lead to muscle atrophy and joint stiffness.

It is essential to promote movement and function in individuals with rheumatoid arthritis to prevent further complications.

Choice B rationale:

Teaching the client self-administration of corticosteroid injections can provide pain relief and reduce inflammation in affected joints.

This is a valuable intervention for managing rheumatoid arthritis symptoms.

Choice C rationale:

Providing emotional support and counseling to address body image concerns is essential for the overall well-being of the client.

However, it does not directly address joint deformities, which are the primary concern in this scenario.

Choice D rationale:

Instructing the client to apply ice packs to inflamed joints daily may provide temporary relief of symptoms but does not address joint deformities.

Ice should be used cautiously in RA, as extreme cold can worsen joint stiffness.
