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?

Choice A Reason: Hypoglycemia (low blood sugar) is not a common adverse effect of atorvastatin. Choice B Reason: Daytime drowsiness is not a typical side effect of statin medications and is more commonly associated with other types of medications, such as sedatives or sleep aids. Choice C Reason: Muscle pain is correct. The nurse should instruct the client to monitor and report muscle pain (myalgia) to the healthcare provider when taking atorvastatin. Myalgia is a potential adverse effect of statin medications, and in rare cases, it can progress to a more serious condition called rhabdomyolysis, which involves muscle breakdown and can lead to kidney damage. Therefore, any new or unexplained muscle pain, tenderness, or weakness should be reported promptly to the healthcare provider for evaluation. Choice D Reason: Palpitations (rapid or irregular heartbeats) are not commonly associated with atorvastatin use. If a client experiences palpitations, it may be related to other factors or conditions and should be evaluated separately.
