A nurse is preparing to administer filgrastim 480 mcg subcutaneously daily. Filgrastim injection 300 mcg/mL is available. How many mL should the nurse administer per dose? Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero."
The Correct Answer is ["1.6 mL"]
To calculate the number of mL the nurse should administer per dose, you need to divide the dose of filgrastim in mcg by the concentration of the filgrastim injection in mcg/mL.
480 mcg ÷ 300 mcg/mL = 1.6 mL
So, the nurse should administer 1.6 mL of filgrastim injection per dose.

Correct Answer is A
Explanation
The nurse should identify **Kilogram** as a metric unit. The other units listed - Pound, Minim, and Ounce - are not metric units.
Correct Answer is ["0.8 mL"]
Explanation
First, the child's weight needs to be converted from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
68 lb ÷ 2.2 = 30.9 kg
Next, the dose of diphenhydramine in mg can be calculated by multiplying the child's weight in kg by the dose in mg/kg.
1.25 mg/kg × 30.9 kg = 38.6 mg
Finally, to calculate the number of mL the nurse should administer, you need to divide the dose of diphenhydramine in mg by the concentration of the diphenhydramine injection in mg/mL.
38.6 mg ÷ 50 mg/mL = 0.8 mL
So, the nurse should administer 0.8 mL of diphenhydramine injection.
