A nurse is preparing to administer fligrastin 5 mcg/kg subcutaneous to a client who weighs 143 lb. Available is fligrastin 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 ["1.1"]
Calculation:
Convert the client's weight from pounds (lbs) to kilograms (kg):
Formula: Weight in kg = Weight in lbs / 2.2 lbs/kg
= 143 lbs / 2.2 lbs/kg
≈ 65 kg
Calculate the total dose of filgrastim needed in micrograms:
Ordered dose: 5 mcg/kg
Client's weight in kg: 65 kg
Formula: Total dose (mcg) = Ordered dose (mcg/kg) × Client's weight (kg)
= 5 mcg/kg × 65 kg
= 325 mcg
Determine the concentration of the available filgrastim solution:
Available concentration: 300 mcg/mL
Calculate the volume of filgrastim to administer:
Formula: Volume to administer (mL) = Desired dose (mcg) / Concentration (mcg/mL)
= 325 mcg / 300 mcg/mL
≈ 1.0833 mL
Round the answer to the nearest tenth:
1.0833 mL rounding to the nearest tenth gives us 1.1 mL.

Correct Answer is ["250"]
Explanation
Calculation:
Convert the total volume to milliliters:
Total volume: 1.5 L
Conversion: 1.5 L × 1000 mL/L = 1500 mL
Determine the total infusion time in hours:
Infusion time: 6 hours
Calculate the IV pump flow rate in mL/hr:
Formula: Flow rate (mL/hr) = Total volume (mL) / Total time (hours)
= 1500 mL / 6 hours
= 250 mL/hr
Correct Answer is ["14"]
Explanation
Calculation:
Determine the total volume to be infused:
Total volume: 250 mL
Determine the total infusion time in minutes:
Infusion time: 3 hours × 60 minutes/hour = 180 minutes
Determine the drop factor of the IV tubing:
Drop factor: 10 gtt/mL
Calculate the total number of drops needed:
Formula: Total drops (gtt) = Total volume (mL) × Drop factor (gtt/mL)
= 250 mL × 10 gtt/mL
= 2500 gtt
Calculate the flow rate in drops per minute (gtt/min):
Formula: Flow rate (gtt/min) = Total drops (gtt) / Total time (minutes)
= 2500 gtt / 180 minutes
≈ 13.89 gtt/min
Round the answer to the nearest whole number:
13.89 gtt/min rounded to the nearest whole number is 14 gtt/min.
