A nurse is reinforcing teaching with a client who has lupus. Which of the following health conditions should the nurse include in the reinforced teaching?

A. Bone degeneration: While steroids used for lupus can cause osteoporosis, the disease itself is primarily an inflammatory connective tissue disorder. B. Diabetes: Lupus is not a direct cause of diabetes, though steroid treatments can increase blood sugar. C. Cardiovascular disease: Systemic Lupus Erythematosus (SLE) causes chronic inflammation that can damage the heart and blood vessels, significantly increasing the risk of atherosclerosis and heart disease. D. Infertility: Many women with lupus can conceive, though the pregnancy is considered high-risk. It is not a primary "condition" of the disease itself in the same way CV disease is.
