A nurse is preparing to administer methylprednisolone sodium succinate 80 mg IV bolus. The nurse reconstitutes the 125 mg in the vial in powder form to 2 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Determine the available concentration of the reconstituted solution in mg/mL. Vial content: 125 mg Reconstitution volume: 2 mL Available concentration (mg/mL) = 125 mg / 2 mL = 62.5 mg/mL. Calculate the volume to administer in milliliters (mL). Desired dose: 80 mg Available concentration: 62.5 mg/mL Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 80 mg / 62.5 mg/mL = 1.28 mL. Round the answer to the nearest tenth. = 1.3 mL.
