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?
Urine specific gravity 1.020.
BUN 15 mg/dL.
LDL 120 mg/dL.
Blood glucose 90 mg/dL.
The Correct Answer is C
Atorvastatin is a medication that belongs to a group of drugs called statins. It is used to lower blood levels of “bad” cholesterol (low-density lipoprotein, or LDL), to increase levels of “good” cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood). The treatment has been effective if the LDL level is reduced, as high LDL levels can increase the risk of heart disease and stroke. A normal range for LDL is less than 100 mg/dL.
Choice A is wrong because urine specific gravity is a measure of how concentrated the urine is, not how much cholesterol is in the blood. A normal range for urine specific gravity is 1.005 to 1.0304.
Choice B is wrong because BUN (blood urea nitrogen) is a measure of how well the kidneys are working, not how much cholesterol is in the blood. A normal range for BUN is 7 to 20 mg/dL.
Choice D is wrong because blood glucose is a measure of how much sugar is in the blood, not how much cholesterol is in the blood.
A normal range for blood glucose is 70 to 100 mg/dL.
