Calculation
A client is receiving methylprednisolone 40 mg IV. The nurse prepares the dose using a vial containing methylprednisolone 125 mg/2 mL. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth).
mL
Explanation & Rationale
Desired dose = 40 mg Available concentration = 125 mg / 2 mL = 62.5 mg/mL Calculate the volume to administer: Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 40 mg / 62.5 mg/mL = 0.64 mL
