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.)

- Calculate the dose of methylprednisolone in mL using the formula: Dose (mL) = Ordered Dose (mg) / Available Dose (mg) x Available Volume (mL) - Substitute the values from the question: Dose (mL) = 40 mg / 125 mg x 2 mL - Simplify the expression: Dose (mL) = 0.64 mL - Round to the nearest hundredth if needed: Dose (mL) = 0.64 mL - The nurse should administer 0.64 mL of medication.
