A nurse is assessing a client who has hypercholesterolemia and is receiving simvastatin. Which of the following findings should the nurse recognize as a potential adverse effect?

A. Blurred vision is not a common adverse effect of simvastatin. It is important to monitor for other symptoms like muscle pain or weakness when taking this medication. B. Muscle weakness or pain (myopathy) is a well-known adverse effect of statins, including simvastatin. This can range from mild discomfort to more serious conditions like rhabdomyolysis. C. Orthostatic hypotension is not typically associated with simvastatin use. Statins primarily affect lipid levels and not blood pressure. D. Urinary retention is not a known side effect of simvastatin. It is more commonly associated with medications like antihistamines or opioids.
