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 B
Explanation
Gastric bleeding can occur due to peptic ulcer disease, nonsteroidal anti inflammatory drugs (NSAIDs), or anticoagulants.
Choice C is wrong because cough is not a common adverse effect of morphine administered via continuous epidural infusion.
Cough can be caused by respiratory infections, asthma, or chronic obstructive pulmonary disease (COPD).
Choice D is wrong because tachypnea is not a common adverse effect of morphine administered via continuous epidural infusion.
Tachypnea can be caused by hypoxia, anxiety, pain, or fever. Morphine can cause respiratory depression, which is characterized by bradypnea, not tachypnea.
Correct Answer is B
Explanation
This is because hydromorphone is a controlled substance and any unused portion should be discarded in the presence of a witness. Some possible explanations for the other choices are:
Choice A is wrong because storing the remaining half of the pill in the automated medication dispensing system could lead to errors in dosage or diversion of the drug.
Choice C is wrong because returning the remaining medication to the facility’s pharmacy is not a recommended practice for controlled substances and could also result in errors or diversion.
Choice D is wrong because placing the remaining half of the pill in the unit-dose package could compromise the integrity and stability of the medication and expose it to environmental factors.
Normal ranges for hydromorphone are not applicable as it is a synthetic opioid analgesic that does not have a therapeutic level.
However, some factors that may affect its pharmacokinetics and pharmacodynamics are age, weight, renal function, liver function, genetic polymorphisms, and drug interactions.
