Safe daily dosage range:

Answer 1

After converting the child's weight from pounds to kilograms, the safe daily dosage range of cefuroxime for a child weighing 55 lb is calculated to be 1247.38 mg to 2494.76 mg.

Step-by-step explanation:

The safe dosage range for cefuroxime (Zinacef) for a child is 50-100 mg/kg/day. To calculate this, we need to first convert the child's weight from pounds to kilograms. Since one pound is equal to 0.453592 kilograms, we multiply the child's weight by this conversion factor.

55 lb * 0.453592 = 24.9476 kg

Now, we calculate the safe dosage range in milligrams:

• Minimum safe dosage: 24.9476 kg * 50 mg/kg = 1247.38 mg/day
• Maximum safe dosage: 24.9476 kg * 100 mg/kg = 2494.76 mg/day

Therefore, the safe daily dosage range of cefuroxime for this child is 1247.38 mg to 2494.76 mg.
