A child weighing 52.5 pounds receives a prescription for asparaginase 4,780 IU IV. The vial is labeled, "Asparaginase 10,000 IU single use vial. For IM use, reconstitute in 2 mL sterile sodium chloride, and for IV use, reconstitute in 5 mL." How many mL should the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest tenth.)

Step 1: Identify the concentration after IV reconstitution. Total medication in vial = 10,000 IU Total volume after IV reconstitution = 5 mL Step 2: Calculate the concentration per mL. 10,000 IU ÷ 5 mL = 2,000 IU per mL Step 3: Identify the prescribed dose. Prescribed dose = 4,780 IU Step 4: Calculate the volume to administer. 4,780 IU ÷ 2,000 IU per mL = 2.39 mL Step 5: Round to the nearest tenth. 2.39 mL rounds to 2.4 mL The correct answer is: 2.4
