A nurse is administering the disease-modifying anti-rheumatic medication hydroxychloroquine to a client who has rheumatoid arthritis. Which of the following potential health conditions should the nurse inform the client may occur?

A. Development of ulcers: While GI upset can occur, ulcers are more commonly associated with NSAIDs or steroids than with hydroxychloroquine. B. Eye problems: Hydroxychloroquine (Plaquenil) can cause retinal toxicity and irreversible vision loss. Patients must have regular ophthalmic examinations (every 6–12 months) to monitor for retinopathy. C. Weight fluctuations: Significant weight changes are not a primary or hallmark side effect of this specific medication. D. High cholesterol: Hydroxychloroquine does not typically elevate lipid levels; in some studies, it has actually shown a mild lipid-lowering effect.
