Final answer:
The safe dose range for Vantin for a child weighing 50 lbs is approximately 34.05 mg - 68.1 mg per day.
Step-by-step explanation:
The safe dose range for Vantin for a child weighing 50 lbs is calculated based on the child's weight. The safe dose range is 1.5 - 3 mg/kg/day. To calculate the safe dose for the child, we first need to convert their weight from lbs to kg.
50 lbs is approximately 22.7 kg.
Using the safe dose range of 1.5 - 3 mg/kg/day, we can calculate the safe dose range for the child:
1.5 mg/kg/day * 22.7 kg = 34.05 mg/day
3 mg/kg/day * 22.7 kg = 68.1 mg/day
Therefore, the safe dose range per day for the child weighing 50 lbs is approximately 34.05 mg - 68.1 mg
