Which problem reported by a client taking lovastatin requires the most immediate follow-up by the nurse?

Choice A rationale: Diarrhea and flatulence are common side effects of statin medications like lovastatin but are typically not considered emergencies. They may be managed with dietary adjustments or over-the-counter remedies. Choice B rationale: Muscle pain, especially if severe, requires the most immediate follow-up by the nurse. Muscle pain can be a symptom of a rare but serious side effect called rhabdomyolysis, which can lead to muscle breakdown and potential kidney damage. Prompt assessment and intervention are necessary if severe muscle pain occurs. Choice C rationale: Altered taste is a side effect of lovastatin but is generally not considered a medical emergency. It may affect the client's quality of life but does not require immediate follow-up. Choice D rationale: Abdominal cramps may occur as a side effect of lovastatin, but they are not typically considered an emergency. Like choice A, abdominal cramps can often be managed with dietary adjustments or over-the-counter remedies.
