A nurse is preparing to administer darbepoetin 0.45 mcg/kg subcutaneous once weekly to a client who weighs 198 lb. The amount available is Darbepoetin 300 mcg/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 ["0.1"]

To calculate the dose of darbepoetin that the nurse should administer, we can follow these steps:

Convert the client's weight from pounds to kilograms:

   198 lb ÷ 2.2 = 89.82 kg (rounded to two decimal places)

Calculate the dose of darbepoetin:

   0.45 mcg/kg × 89.82 kg = 40.41 mcg

Determine the volume of darbepoetin needed using the available concentration:

   40.41 mcg ÷ 300 mcg/mL = 0.1347 mL

Rounding to the nearest tenth, the nurse should administer 0.1 mL of darbepoetin subcutaneously once weekly.

Correct Answer is ["0.75"]

Explanation

To calculate the amount of heparin 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) = (7,500 units / 10,000 units/mL)

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

Amount to administer (mL) = (7,500 / 10,000) = 0.75 mL

So, the nurse should administer 0.75 mL of heparin subcutaneously.

Correct Answer is ["750"]

Explanation

To calculate the infusion rate for the first 8 hours, we can use the following formula:

Infusion rate (mL/hr) = (Volume to be infused / Time for infusion)

First, we need to find the volume to be infused in the first 8 hours:

Volume for the first 8 hours = Total volume / 2 = 12 L / 2 = 6 L = 6000 mL

Now we can calculate the infusion rate for the first 8 hours:

Infusion rate = 6000 mL / 8 hr = 750 mL/hr

Therefore, the nurse should set the IV pump to deliver 750 mL/hr during the first 8 hours.
