Final answer:
Further teaching is needed when the client with SLE identifies exercise as an exacerbating factor, as stress, sunlight exposure, and lack of rest are known triggers, but not exercise (c).
Step-by-step explanation:
The client with a new diagnosis of systemic lupus erythematosus (SLE) shows a need for further teaching if she identifies exercise as a factor that can exacerbate SLE. It is well-known that factors such as stress, sunlight exposure, and lack of adequate rest can worsen the symptoms of SLE.
Exercise, when done appropriately, is generally beneficial for individuals with SLE and does not exacerbate the condition; it can help maintain cardiovascular health, reduce stress, and improve overall well-being. Education on avoiding known triggers like UV light and managing stress is critical for patients with SLE to prevent flare-ups and manage symptoms effectively.
