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.

Explanation
This is because the umbilicus is a potential site of infection and should be avoided when administering subcutaneous heparin.
Choice B is wrong because massaging the site after administering the medication can cause bruising and hematoma formation.
Choice C is wrong because a 21-gauge needle is too large for subcutaneous injection and can cause tissue trauma and bleeding.
A smaller needle, such as 25- or 27-gauge, should be used.
Choice D is wrong because aspirating before injecting the medication can increase the risk of hematoma formation and is not recommended for subcutaneous heparin.
Correct Answer is D
Explanation
Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease1 and should be used with caution in patients with hepatic impairment or active liver disease. Alcohol use disorder can cause liver damage and increase the risk of acetaminophen toxicity.
Choice A is wrong because hepatitis B vaccine within the last week is not a contraindication for receiving acetaminophen.
There is no evidence that acetaminophen interferes with the immune response to the vaccine or causes adverse effects.
Choice B is wrong because chronic kidney disease is not a contraindication for receiving acetaminophen.
Acetaminophen is mainly metabolized by the liver and has minimal renal excretion.
However, patients with chronic kidney disease should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
Choice C is wrong because diabetes mellitus is not a contraindication for receiving acetaminophen.
Acetaminophen does not affect blood glucose levels or interact with oral antidiabetic drugs.
However, patients with diabetes mellitus should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
