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.)

Here's the calculation to determine the volume to administer: 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: Volume to administer (mL) = Dose (mg) / Concentration (mg/mL) Since the concentration is given in mg per 2 mL, we need to adjust it to mg/mL for accurate calculation: Concentration (mg/mL) = Total mg / Volume (mL) Concentration (mg/mL) = 125 mg / 2 mL Concentration (mg/mL) = 62.5 mg/m Now, with the concentration in mg/mL, we can calculate the volume to administer: Volume to administer (mL) = 40 mg / 62.5 mg/mL Volume to administer (mL) = 0.64 mL (round to nearest hundredth as requested) Therefore, the nurse should administer 0.64 mL of methylprednisolone.
