Correct Answer is ["0.45"]
Explanation
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 ["1.5"]
Explanation
Step-by-step calculation:
The desired dose of ibuprofen is 150 mg.
The available medication concentration is 100 mg/5 mL.
We need to convert mL to tsp.
Calculating the volume to administer in mL:
Use the concentration of the medication: 150 mg ÷ (100 mg/5 mL) = 150 mg ÷ 20 mg/mL = 7.5 mL
Converting mL to tsp:
1 tsp = 5 mL
7.5 mL ÷ 5 mL/tsp = 1.5 tsp
