A nurse is caring for a client who is taking rosuvastatin. Which of the following findings should the nurse report to the provider immediately?

A. Dyspepsia: While dyspepsia can be uncomfortable, it is not a critical finding that requires immediate reporting to the provider. It may be a common side effect of statins but typically does not warrant urgent intervention. B. Elevated creatine kinase: An elevated creatine kinase level can indicate muscle damage, which is a serious side effect associated with rosuvastatin and other statins. This finding requires immediate reporting to prevent complications such as rhabdomyolysis. C. Headache: A headache may occur with many medications and does not usually require immediate reporting unless it is severe or persistent. D. Mostly cloudy: This option does not pertain to any specific clinical finding or symptom and is therefore not relevant to the question. E. Decreased HDL cholesterol: While low HDL cholesterol can be a concern, it is not as urgent as elevated creatine kinase levels and typically does not require immediate action.
