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.)
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 ["2.8"]
Explanation
Convert the patient's weight from pounds to kilograms:
154 lb ÷ 2.2 = 70 kg
Calculate the dose of pentamidine:
4 mg/kg × 70 kg = 280 mg
Determine the volume to be administered:
We have 100 mg/mL concentration of pentamidine.
280 mg ÷ 100 mg/mL = 2.8 mL
Therefore, the nurse should administer 2.8 mL of pentamidine to the client.
Correct Answer is ["150"]
Explanation
To calculate the IV pump rate for the 0.9% sodium chloride 1,200 mL IV to infuse over 8 hours, we can use the following formula:
IV pump rate (mL/hr) = Total volume (mL) / Time (hr)
Using the given values:
Total volume = 1,200 mL
Time = 8 hours
Plugging these values into the formula:
IV pump rate = 1,200 mL / 8 hr
IV pump rate = 150 mL/hr
So, the nurse should set the IV pump to deliver 150 mL/hr to infuse the 1,200 mL of 0.9% sodium chloride over 8 hours.
