A nurse is reinforcing teaching with a client who has a new prescription for atorvastatin. For which of the following adverse effects should the nurse instruct the client to monitor and report to the provider?

Atorvastatin is a medication used to lower cholesterol levels in the blood. One of the potential adverse effects of atorvastatin is myopathy, a condition characterized by muscle pain, weakness, and tenderness. In severe cases, myopathy can progress to rhabdomyolysis, a potentially life-threatening condition in which muscle breakdown products are released into the bloodstream and can cause kidney damage. Therefore, the nurse should instruct the client to monitor for muscle pain, weakness, or tenderness and report these symptoms to the healthcare provider immediately. Hypoglycemia, palpitations, and daytime drowsiness are not commonly associated with atorvastatin use and would not require immediate reporting to the healthcare provider.
