How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
Step by step calculation:
The child's weight is 22 lb.
The medication dosage is 3 mg/kg.
The available medication concentration is 45 mg/0.6 mL.
Calculating the total dose in mg per dose:
Convert the child's weight to kg: 22 lb ÷ 2.2 lb/kg = 10 kg
Calculate the total dose per dose: 10 kg × 3 mg/kg = 30 mg
Calculating the volume to administer per dose:
Use the concentration of the medication: 30 mg ÷ (45 mg/0.6 mL) = 30 mg ÷ 75 mg/mL = 0.4 mL
