Which action should a nurse take to prevent deformities in a client experiencing an exacerbation of arthritis?

Maintaining joints in functional alignment when resting is crucial for preventing deformities in clients experiencing an exacerbation of arthritis. When joints are not properly aligned, there is a risk of contractures or deformities developing due to muscle imbalances and prolonged immobility. Proper alignment supports optimal positioning and can help alleviate stress on the joints, promoting a healthier range of motion and preventing stiffness.

Encouraging motion of the joint can be beneficial in managing symptoms of arthritis, but if the joints are not correctly aligned during rest, movement may not be effective in preventing deformities. Administering pain medication before therapy is important for pain management but does not directly contribute to the prevention of deformities. Limiting all joint movements is counterproductive as it can lead to further stiffness and potential deformities rather than preserving joint function and alignment.
