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

Explanation
Calculate the size of each of the three equal doses:
Dose per administration (mg) = Total daily dose (mg) / Number of doses per day
= 1200 mg / 3 doses
= 400 mg
Identify the amount of magnesium oxide in each capsule:
Amount per capsule = 400 mg
Calculate the number of capsules to administer with each dose:
Number of capsules per dose = Desired dose per administration (mg) / Amount per capsule (mg/capsule)
= 400 mg / 400 mg/capsule
= 1 capsule
Correct Answer is ["1250"]
Explanation
Convert the child's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 55 pounds / 2.2 pounds/kg
= 25 kg
Calculate the total daily dose in milligrams:
Total daily dose (mg) = Prescribed dose (mg/kg/24 hours) x Child's weight (kg)
= 300 mg/kg/24 hours x 25 kg
= 7500 mg/24 hours
Determine the number of doses per day:
Number of doses per day = 24 hours / Frequency of doses (hours)
= 24 hours / 4 hours/dose
= 6 doses/day
Calculate the dose to administer for each dose:
Dose per administration (mg) = Total daily dose (mg) / Number of doses per day
= 7500 mg / 6 doses
= 1250 mg/dose
