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?
A.
Hypoglycemia
B.
Palpitations
C.
Daytime drowsiness
D.
Muscle pain
The Correct Answer and Explanation is:
The correct answer is D. Muscle pain.
Explanation:
Atorvastatin, a statin medication, is commonly prescribed to lower cholesterol levels and reduce the risk of cardiovascular events. While effective, atorvastatin and other statins have potential adverse effects that need to be monitored. One of the most serious adverse effects associated with atorvastatin is muscle pain or myopathy, which can sometimes progress to a more severe condition called rhabdomyolysis.
Muscle Pain (Myopathy):
Muscle pain, tenderness, or weakness is a key adverse effect of statins like atorvastatin. This is due to the statin-induced disruption of muscle cell function. The pathophysiology involves the inhibition of the enzyme HMG-CoA reductase, which, while reducing cholesterol synthesis, can also impact muscle cells. Myopathy can range from mild muscle aches to severe pain and weakness. In rare cases, it can progress to rhabdomyolysis, a serious condition where muscle breakdown leads to the release of muscle cell contents into the bloodstream, potentially causing kidney damage and failure. Symptoms of rhabdomyolysis include severe muscle pain, dark urine, and elevated creatine kinase levels.
Monitoring and Reporting:
Clients on atorvastatin should be instructed to promptly report any new or worsening muscle pain, tenderness, or weakness to their healthcare provider. Early detection and intervention can help prevent the progression to more severe conditions like rhabdomyolysis. The provider may recommend discontinuing the medication or adjusting the dosage based on the severity of the symptoms.
Other Options:
- A. Hypoglycemia: This is not a common adverse effect of atorvastatin. Statins generally do not impact blood sugar levels significantly.
- B. Palpitations: Atorvastatin is not typically associated with palpitations. Cardiovascular side effects are less common but not characteristic of atorvastatin.
- C. Daytime Drowsiness: This is not a typical side effect of atorvastatin. Statins are not known to cause sedation or drowsiness.
In summary, while atorvastatin is an effective medication for lowering cholesterol, muscle pain is a notable adverse effect that requires careful monitoring.
