A nurse is reviewing the laboratory values of a client who is taking atorvastatin. Which of the following laboratory values indicates the treatment has been effective?
A Urine specific gravity 1.020.
B BUN 15 mg/dL.
C LDL 120 mg/dL.
D Blood glucose 90 mg/dL.
The Correct answer and Explanation is:
The correct answer is C: LDL 120 mg/dL.
Atorvastatin is a statin medication primarily used to lower low-density lipoprotein (LDL) cholesterol levels, which are often referred to as “bad” cholesterol. Elevated LDL levels are associated with an increased risk of cardiovascular diseases, including heart attack and stroke. The primary goal of atorvastatin therapy is to reduce LDL levels to within target ranges, which are typically below 100 mg/dL for individuals at high risk for cardiovascular events.
When assessing the effectiveness of atorvastatin treatment, monitoring LDL cholesterol levels is crucial. An LDL level of 120 mg/dL indicates a significant reduction compared to baseline levels, especially if the client started with levels well above this range. The effectiveness of atorvastatin can be determined by comparing current LDL levels to previous measurements taken before the initiation of therapy or during follow-up assessments.
The other options presented are not directly relevant to the effectiveness of atorvastatin treatment:
- A: Urine specific gravity 1.020 is a measure of urine concentration and does not provide information about cholesterol levels or the efficacy of atorvastatin.
- B: BUN 15 mg/dL (blood urea nitrogen) is primarily used to assess kidney function and hydration status, rather than lipid levels.
- D: Blood glucose 90 mg/dL reflects normal glucose metabolism but does not indicate anything regarding cholesterol management or statin effectiveness.
In summary, the primary indicator of atorvastatin’s effectiveness is a decrease in LDL cholesterol levels, making option C the correct answer. Regular monitoring of lipid profiles is essential for clients on statin therapy to ensure they are achieving their cholesterol-lowering goals and to adjust treatment as necessary.
