Filgrastim 5 mcg/kg/day subcutaneous is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled 300 mcg/mL. How many mL should the nurse administer daily to this child?
(Enter the numerical value only. If rounding required, round to the nearest tenth.)
The Correct Answer is ["0.7"]
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the dose of filgrastim in mcg by multiplying the weight in kg by the dosage in mcg/kg/day
- Divide the dose in mcg by the concentration of filgrastim in mcg/mL
- Round the result to the nearest tenth
Using these steps, we get:
- (weight in kg) = (88) / (2.2) = 40 kg
- (dose in mcg) = (5) x (40) = 200 mcg
- (volume in mL) = (200) / (300) = 0.667 mL
- (rounded volume in mL) = 0.7 mL
Therefore, the nurse should administer 0.7 mL of filgrastim to this child daily.

Correct Answer is ["10.2"]
Explanation
To determine the infusion rate in mL/hour for the dopamine solution:
-
Calculate the total dose per minute:
3 mcg/kg/min×91 kg=273 mcg/min3mcg/kg/min×91kg=273mcg/min. -
Convert mcg/min to mcg/hour:
273 mcg/min×60 min/hour=16,380 mcg/hour273mcg/min×60min/hour=16,380mcg/hour. -
Convert mcg to mg:
16,380 mcg÷1,000=16.38 mg/hour16,380mcg÷1,000=16.38mg/hour. -
Determine the concentration of the solution:
400 mg÷250 mL=1.6 mg/mL400mg÷250mL=1.6mg/mL. -
Calculate the mL/hour required:
16.38 mg/hour÷1.6 mg/mL=10.2375 mL/hour16.38mg/hour÷1.6mg/mL=10.2375mL/hour.
Rounded to the nearest tenth:
10.2 mL/hour.
Correct Answer is ["250"]
Explanation
To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (500 / 120) x 60
Simplifying, we get:
(mL/hour) = 4.167 x 60
(mL/hour) = 250
Therefore, the nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS to the patient.
