A nurse is preparing to administer buprenorphine 4 mcg/kg IV bolus to a child who weighs 74 lb. Available is buprenorphine injection 0.3 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.45"]
Calculating the total dose in mg:
Convert the child's weight to kg: 74 lb ÷ 2.2 lb/kg = 33.64 kg
Calculate the total dose: 33.64 kg × 4 mcg/kg = 134.56 mcg
Converting mcg to mg:
1 mg = 1000 mcg
134.56 mcg ÷ 1000 mcg/mg = 0.13456 mg
Calculating the volume to administer:
Use the concentration of the medication: 0.13456 mg ÷ 0.3 mg/mL = 0.45 mL

Correct Answer is ["3.5"]
Explanation
Convert the child’s weight from pounds to kilograms:
52 lb÷2.2=23.6 kg.
Calculate the total daily dose in micrograms (mcg):
7.5 mcg/kg/day×23.6 kg=177 mcg/day.
Determine the volume in mL to administer:
The elixir concentration is 50 mcg/mL
177 mcg÷50 mcg/mL=3.54 mL.

3.54 rounds to 3.5 mL.
Correct Answer is ["2.3"]
Explanation
Step-by-step calculation:
The child's weight is 77 lb.
The medication dosage is 10 mg/kg.
The available medication concentration is 150 mg/mL.
Calculating the total dose in mg:
Convert the child's weight to kg: 77 lb ÷ 2.2 lb/kg = 35 kg
Calculate the total dose: 35 kg × 10 mg/kg = 350 mg
Calculating the volume to administer:
Use the concentration of the medication: 350 mg ÷ 150 mg/mL = 2.33 mL
Rounding the answer:
2.33 rounds to 2.3 mL
