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

Here's the calculation: Prescribed dose: 40 mg methylprednisolone Medication vial concentration: 125 mg per 2 mL (given on the vial label) We need to find the volume (mL) containing the prescribed dose (40 mg) of methylprednisolone. Calculation: Concentration adjustment: The concentration is given in mg per 2 mL. To calculate the medication needed for the 40 mg dose, we need the concentration in mg/mL. Concentration (mg/mL) = Total mg / Volume (mL) Concentration (mg/mL) = 125 mg / 2 mL Concentration (mg/mL) = 62.5 mg/mL Volume to administer: Volume to administer (mL) = Dose (mg) / Concentration (mg/mL) Volume to administer (mL) = 40 mg / 62.5 mg/mL Volume to administer (mL) = 0.64 mL (round to nearest hundredth) Therefore, the nurse should administer 0.64 mL of methylprednisolone.
