A client arrives at the healthcare setting currently taking atorvastatin (Lipitor) daily. Which assessment finding associated with atorvastatin (Lipitor) would need immediate reporting to the healthcare provider?
bradycardia
dark-red urine
elevated HDL cholesterol
migraine headache
The Correct Answer is B
A. Bradycardia is not a common side effect of atorvastatin and would not necessarily require immediate reporting unless it is significantly low and symptomatic.
B. Dark-red urine could indicate the presence of myoglobinuria, which can occur due to rhabdomyolysis, a serious side effect of statins like atorvastatin that necessitates immediate medical attention.
C. Elevated HDL cholesterol is generally a positive finding and does not require reporting unless it is part of a larger adverse effect context.
D. A migraine headache, while concerning, is not a known side effect specifically associated with atorvastatin and may not require immediate intervention unless severe or persistent.
