A nurse is preparing to administer methylprednisolone 7 mg/kg/day IM in two divided doses to a school-age child who weighs 64 lb. Available is methylprednisolone 20 mg/mL. 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 ["5.1"]
To calculate the correct dose of methylprednisolone, we need to follow these steps:
-
Convert pounds to kilograms:
- 64 lb * 0.4536 kg/lb = 29 kg
-
Calculate the daily dose in milligrams:
- 7 mg/kg/day * 29 kg = 203 mg/day
-
Calculate the dose per administration:
- Since the medication is divided into two doses, divide the daily dose by 2:
- 203 mg/day / 2 = 101.5 mg/dose
- Since the medication is divided into two doses, divide the daily dose by 2:
-
Determine the volume needed from the available concentration:
- 101.5 mg * (1 mL / 20 mg) = 5.075 mL
Therefore, the nurse should administer 5.1 mL of methylprednisolone per dose.

Correct Answer is ["0.75"]
Explanation
1. Dosage and Concentration:
Methylprednisolone acetate dosage: 60 mg
Methylprednisolone acetate concentration: 80 mg/mL (available suspension)
2. Volume Calculation:
We can use the following formula to find the volume to administer:
Volume (mL) = Dosage (mg) / Concentration (mg/mL)
Volume (mL) = 60 mg / 80 mg/mL
3. Rounding the Answer:
Round the answer to the nearest hundredth of a milliliter.
Volume (mL) = 0.75 mL (rounded to two decimal places)
Therefore, the nurse should administer 0.75 mL of methylprednisolone acetate suspension for injection.
