A nurse is reviewing laboratory data for a client who is taking simvastatin to correct plasma lipid levels. Which of the following findings should the nurse identify as an adverse effect of this therapy?

A. "Elevated alanine aminotransferase (ALT)": Simvastatin can cause liver damage, which may result in elevated liver enzymes such as ALT. Monitoring liver function is essential during statin therapy to detect potential liver injury early. B. "Elevated troponin T": Troponin T is a marker for myocardial injury and is typically elevated in cases of heart attack. Simvastatin is not known to affect troponin T levels, so an elevated level would not be an expected adverse effect. C. "Elevated WBC count": An elevated WBC count may indicate an infection or inflammation, but it is not a common or expected adverse effect of simvastatin. Statins are not typically associated with changes in white blood cell count. D. "Elevated thyroid-stimulating hormone (TSH)": An elevated TSH level suggests hypothyroidism, but this is not an adverse effect of simvastatin. Statins do not commonly affect thyroid function tests.
