Choice A rationale Crushing hydroxychloroquine tablets can alter the drug’s release and absorption, potentially leading to suboptimal therapeutic effects or increased side effects. Choice B rationale Discontinuing hydroxychloroquine when symptoms subside can lead to a flare-up of rheumatoid arthritis symptoms. It is important to continue the medication as prescribed to maintain disease control. Choice C rationale Regular eye exams are necessary while taking hydroxychloroquine because the medication can cause retinal toxicity, which can lead to vision changes or loss if not monitored and managed appropriately.
