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."

Answer and Explanation

The Correct Answer is ["1.6"]

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 ["0.8"]

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.

Correct Answer is ["1"]

Explanation

The first step is to convert the client's weight from pounds (lb) to kilograms (kg).

146.7 lb ÷ 2.2 lb/kg = 66.68 kg

Next, the nurse should calculate the total dose of metronidazole the client needs.

7.5 mg/kg x 66.68 kg = 500.1 mg

Since the available tablets are 500 mg each, the nurse should administer:

500.1 mg ÷ 500 mg/tablet = 1 tablet (rounded to the nearest whole number)
