The nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled "125 mg per 2 mL." How many mL of medication should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth.)

First, calculate the concentration of methylprednisolone in the vial by dividing the amount of medication by the volume of solution: 125 / 2 = 62.5 mg/mL Next, divide the prescribed dose by the concentration of methylprednisolone: 40 /62.5 =0.64 mL The answer is 0.64 mL.
