A nurse is preparing to administer epoetin 7,000 units subcutaneous for management of anemia related to chronic kidney disease. Available is 10,000 units/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.7"]

To calculate the amount of epoetin to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))

Plugging in the given values:

Amount to administer (mL) = (7,000 units / 10,000 units/mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (7,000 / 10,000) = 0.7 mL

So, the nurse should administer 0.7 mL of epoetin subcutaneously for the management of anemia related to chronic kidney disease.

Correct Answer is D

Explanation

Choice A reason: This choice is incorrect because it does not provide a numerical answer to the question.

Choice B reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is lower than the correct one, which is not true.

Choice C reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is higher than the correct one, which is not true.

Choice D reason: This choice is correct because it is the result of dividing the ordered dose (3.5 mg) by the concentration of the vial (1 mg/mL). The formula for calculating the volume to be drawn up is:

Volume = Dose/Concentration

Therefore, the volume to be drawn up is:

Volume = 3.5 mg/(1 mg/mL) = 3.5 mL

A. High lipid levels B. Blood glucose of 60 C. Platelets over 150,000 D. Low INR

Correct Answer is A

Explanation

Choice A reason: This is correct because high lipid levels, such as cholesterol and triglycerides, are a risk factor for cardiovascular disease. HMG-CoA reductase inhibitors, also known as statins, lower the production of cholesterol in the liver and reduce the risk of heart attack and stroke.

Choice B reason: This is incorrect because blood glucose of 60 is not related to the need for an HMG-CoA reductase inhibitor. Blood glucose of 60 is below the normal range and may indicate hypoglycemia, which is a low blood sugar level. Hypoglycemia can cause symptoms such as dizziness, confusion, sweating, and hunger.

Choice C reason: This is incorrect because platelets over 150,000 are not related to the need for an HMG-CoA reductase inhibitor. Platelets are blood cells that help with clotting and prevent bleeding. The normal range of platelets is 150,000 to 450,000 per microliter of blood. Platelets over 150,000 are within the normal range and do not indicate a problem.

Choice D reason: This is incorrect because low INR is not related to the need for an HMG-CoA reductase inhibitor. INR stands for international normalized ratio and is a measure of how long it takes the blood to clot. The normal range of INR is 0.8 to 1.2. Low INR means the blood clots faster than normal and may indicate a risk of thrombosis, which is a blood clot in a vein or artery.
