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

Explanation
Step-by-step calculation:
The nurse needs to administer 120 mL of sodium chloride.
The infusion time is 30 minutes.
Calculating the flow rate in mL/hr:
