Choice A rationale:

Advising the patient to avoid using assistive devices to maintain independence is incorrect.

Assistive devices can be helpful in reducing joint stress and preserving independence for individuals with RA.

Encouraging their use when necessary is part of joint protection strategies.

Choice B rationale:

Telling the patient that they don't need to modify any activities and continue as usual is not appropriate.

Patients with RA may need to make modifications to their daily activities to protect their joints and manage their condition effectively.

Encouraging appropriate modifications is essential.

Choice C rationale:

Recommending the patient practice joint protection techniques and use assistive devices when necessary is the correct answer.

Joint protection techniques, such as using proper body mechanics and avoiding activities that strain the joints, can help minimize further damage.

Assistive devices like splints or braces can also aid in joint protection.

Choice D rationale:

Suggesting the patient engage in vigorous exercise to strengthen their joints is not appropriate advice.

While exercise is beneficial, it should be tailored to the patient's specific needs and limitations.

Vigorous exercise without proper guidance can exacerbate joint inflammation in RA.
