A premature infant with a birth weight of 1,200 grams is receiving beractant 120 mg intratracheal every 6 hours. Single use vials of beractant are labeled, "100 mg/4 mL." How many mL should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)

The vial is labeled as “100 mg per 4 mL.” This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL). The nurse needs to administer 120 mg of the medication. To find out how many mL this is, we divide the dose by the concentration: Volume in mL = 120 mg / 25 mg/mL ​ = 4.8 mL If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
