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 ["8"]
Explanation
The correct answer is 8 tablets. To find the answer, we can use the following steps:
- Convert the daily maximum dosage from grams to milligrams by multiplying by 1000
- Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet
- Round the result to the nearest whole number
Using these steps, we get:
- (daily maximum dosage in mg) = (5) x (1000) = 5000 mg
- (number of tablets) = (5000) / (625) = 8 tablets
- (rounded number of tablets) = 8
Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.
Correct Answer is ["1"]
Explanation
First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.
Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:
Amount of solution= amount of water + amount of warfarin
Substituting the given values, we get:
Amount of solution = 2.7 + 5 =7.7 mL
Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:
mL of solution = mg of warfarin/ concentration of warfarin
Substituting the given values, we get:
mL of solution = 2/2 = 1 mL
Therefore, the nurse should administer 1 mL of solution to the patient.
