The healthcare provide prescribes filgrastim 5 mcg/kg/day SUBQ for a client who weighs 190 pounds. The medication is available in 480 mcg/1.6 mL vial. How many ml. should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.4"]
Convert the client's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 190 pounds / 2.2 pounds/kg
≈ 86.36 kg
Calculate the prescribed daily dose in micrograms:
Daily dose (mcg) = Prescribed dose (mcg/kg/day) x Client's weight (kg)
= 5 mcg/kg/day x 86.36 kg
≈ 431.8 mcg
Calculate the volume to administer in mL:
Available concentration = 480 mcg / 1.6 mL
= 300 mcg/mL
Volume to administer (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 431.8 mcg / 300 mcg/mL
≈ 1.439... mL
Round to the nearest tenth:
Rounded volume = 1.4 mL

Correct Answer is ["83"]
Explanation
Total volume to be infused = 1 litre
Convert the total volume from liters to milliliters:
Total volume (mL) = Total volume (liters) x 1000 mL/litre
= 1 litre x 1000 mL/litre
= 1000 mL
Total infusion time in hours = 12 hours
Calculate the infusion rate in mL per hour:
Infusion rate (mL/hour) = Total volume (mL) / Total infusion time (hours)
= 1000 mL / 12 hours
≈ 83.33 mL/hour
Round to the nearest whole number:
Rounded infusion rate = 83 mL/hour
Correct Answer is ["5"]
Explanation
Convert the child's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 44 pounds / 2.2 pounds/kg
= 20 kg
Calculate the prescribed dose for the first day:
Dose on day 1 (mg) = Initial dose (mg/kg) x Child's weight (kg)
= 10 mg/kg x 20 kg
= 200 mg
Calculate the volume to administer on the first day:
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 200 mg / (200 mg / 5 mL)
= 5 mL
