Correct Answer is C
Explanation
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.
Choice D rationale
Taking a double dose of hydroxychloroquine can increase the risk of side effects and toxicity. It is important to take the medication as prescribed and not to double up on doses.
Correct Answer is A
Explanation
Choice A rationale
Elevated alanine aminotransferase (ALT) is an adverse effect of simvastatin therapy. Statins, including simvastatin, can cause liver damage, which is indicated by elevated liver enzymes such as ALT2.
Choice B rationale
Elevated troponin T is not typically associated with simvastatin therapy. Troponin T is a marker for cardiac muscle damage, not a common adverse effect of statins.
Choice C rationale
Elevated WBC count is not a known adverse effect of simvastatin therapy. An elevated WBC count usually indicates an infection or inflammation.
Choice D rationale
Elevated thyroid-stimulating hormone (TSH) is not associated with simvastatin therapy. TSH levels are related to thyroid function, not the effects of statins.
