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.

Correct Answer is A
Explanation
Raloxifene is a medication used to prevent and treat osteoporosis in postmenopausal women.
Osteoporosis is a condition that causes bones to become thin and weak, increasing the risk of fractures.
Raloxifene belongs to a class of drugs called selective estrogen receptor modulators (SERMs), which mimic the effects of estrogen on bone density. Choice B is wrong because raloxifene may increase the risk of deep-vein thrombosis (DVT), a type of blood clot that forms in a vein deep in the body. DVT can cause pain, swelling, and redness in the affected limb, and can lead to serious complications such as pulmonary embolism (PE), a blood clot in the lung.
Raloxifene should not be used by people who have or had DVT or PE. Choice C is wrong because raloxifene is not used to treat urinary tract infection (UTI), an infection that affects the bladder, kidneys, or ureters. UTI can cause symptoms such as burning or pain when urinating, frequent or urgent urination, blood in the urine, or fever.
UTI is usually treated with antibiotics.
Choice D is wrong because raloxifene is not used to treat hypothyroidism, a condition that occurs when the thyroid gland does not produce enough thyroid hormone.
Thyroid hormone regulates the body’s metabolism, growth, and development. Hypothyroidism can cause symptoms such as fatigue, weight gain, cold intolerance, dry skin, hair loss, or depression.
Hypothyroidism is usually treated with synthetic thyroid hormone replacement.
Correct Answer is B
Explanation
According to the CDC, people with severe, life-threatening allergies to any ingredient in a flu vaccine (other than egg proteins) should not get that vaccine. However, people with egg allergy can get a flu vaccine. The CDC also states that people who have had a severe allergic reaction to a dose of influenza vaccine should not get that flu vaccine again and might not be able to receive other influenza vaccines. Therefore, a nurse should report an egg allergy to the provider as a possible contraindication to receiving the vaccine.
Choice A is wrong because shellfish is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice C is wrong because milk is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice D is wrong because peanuts are not an ingredient in a flu vaccine and are not a contraindication to receiving the vaccine.
