To convert pounds to kilograms, you can use the conversion factor \(1 \text{ pound} = 0.453592 \text{ kg}\).
First, let's convert 44 pounds to kilograms:
\[ 44 \text{ pounds} \times 0.453592 \text{ kg/pound} \approx 19.96 \text{ kg} \]
For the purpose of medication dosage, we can round this to 20 kg.
Now, the physician ordered Rocephin at a dose of 50 mg per kg. To calculate the total dose for the child:
\[ \text{Total dose (mg)} = 50 \text{ mg/kg} \times 20 \text{ kg} = 1000 \text{ mg} \]
Since the total dose will be given in two divided doses, we can find out how much to give per dose:
\[ \text{Dose per administration (mg)} = \frac{1000 \text{ mg}}{2} = 500 \text{ mg} \]
Summary
- Weight in kg: \( \approx 20 , \text{kg} \)
- Total dose of Rocephin: \( 1000 , \text{mg} \)
- Dose per administration: \( 500 , \text{mg} \) (in two divided doses)
