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.

Explanation
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:
Calculate the total number of minutes for the infusion:
8 hours × 60 minutes/hour = 480 minutes
Determine the total number of drops needed for the infusion:
The total volume to be infused is 1000 mL.
The drop factor is 15 gtt/mL.
1000 mL × 15 gtt/mL = 15000 gtt
Calculate the IV flow rate in drops per minute:
15000 gtt ÷ 480 min ≈ 31 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.
Correct Answer is ["4.5"]
Explanation
To calculate the dose of ondansetron that the nurse should administer, we can follow these steps:
Convert the client's weight from pounds to kilograms:
132 lb ÷ 2.2 = 60 kg
Calculate the dose of ondansetron:
0.15 mg/kg × 60 kg = 9 mg
Determine the volume of ondansetron needed using the available concentration:
9 mg ÷ 2 mg/mL = 4.5 mL
Rounding to the nearest tenth, the nurse should administer 4.5 mL of ondansetron via IV.
