Final answer:
For a client taking atorvastatin to manage hyperlipidemia, the nurse should monitor Liver function tests to ensure the medication is not adversely affecting the liver.
Step-by-step explanation:
A nurse caring for a client taking atorvastatin for hyperlipidemia should monitor Liver function tests (LFTs). Atorvastatin is a medication that can impact liver function because the liver plays a key role in lipid metabolism, including cholesterol synthesis and the production of triglycerides. Elevated liver enzymes may indicate liver damage or dysfunction. Therefore, monitoring LFTs helps ensure that the atorvastatin is not causing harmful effects on the liver.
