A nurse is reviewing the laboratory results of a client who is taking amitriptyline. Which of the following laboratory values should the nurse report to the provider?

WBC count 5,000/mm.

Total bilirubin 1.5 mg/dL.

Hct 44%.

Potassium 5.2 mEq/L.

Answer and Explanation

The Correct Answer is D

A WBC count of 5,000/mm3 is low and could indicate leukopenia, a possible side effect of amitriptyline. Leukopenia increases the risk of infection and should be reported to the provider.

Choice B is wrong because a total bilirubin of 1.5 mg/dL is within the normal range of 0.3 to 1.9 mg/dL.

Choice C is wrong because a Hct of 44% is within the normal range of 37% to 48% for women and 45% to 52% for men.

Choice D is wrong because a potassium level of 4.2 mEq/L is within the normal range of 3.5 to 5.0 mEq/L.

Correct Answer is C

Explanation

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.

A. Expel the air bubble from the syringe prior to injection. B. Apply firm pressure to the injection site following administration. C. Insert the syringe needle halfway into the client’s skin. D. Administer the medication into the client’s muscles.

Correct Answer is B

Explanation

Choice A rationale:

The air bubble should not be expelled from the syringe before administering enoxaparin. The air bubble is included to ensure that the entire dose is administered and to help prevent leakage of the medication into the subcutaneous tissue, which can reduce bruising.

Choice B rationale:

After administering enoxaparin, applying firm pressure (but not massaging) to the injection site helps minimize bruising and bleeding. It's important not to massage the site as this can increase the risk of bleeding.

Choice C rationale:

The needle should be inserted fully into the subcutaneous tissue at a 90-degree angle (or at a 45-degree angle if the client has little subcutaneous tissue). Inserting the needle halfway may result in improper administration.

Choice D rationale:

Enoxaparin is a low-molecular-weight heparin that should be administered subcutaneously, not intramuscularly. Administering it intramuscularly could increase the risk of bleeding and is not the appropriate route for this medication.
