Final answer:
The patient's weight in pounds (88 lbs) is first converted to kilograms (40 kg), and then multiplied by the dosage per kilogram (20 mg/kg) to find the correct dose of Precef, which is 800 mg.
Step-by-step explanation:
The question pertains to dosage calculation, which is a mathematics problem typically encountered in the medical field. First, we need to convert the patient's weight from pounds to kilograms. There are approximately 2.2 pounds in one kilogram.
To convert 88 pounds to kilograms, we divide 88 by 2.2, which equals 40 kilograms. Next, to calculate the correct dose of Precef at 20 mg/kg, we multiply the patient's weight in kilograms by the dosage per kilogram: 40 kg × 20 mg/kg equals 800 mg. Therefore, the correct dose is 800 mg to be administered every 12 hours.
