An adult patient weighs 78 kg . The Physician orders medication to be administered at a rate of \( 3.5 \mathrm{mg} / \mathrm{lb} \). How many mg does the patient require? Select one: 500.6 mg 600.6 mg 400.6 mg 700.6 mg

To calculate the required medication in mg for the patient, we first need to convert the weight from kg to lb. Since 1 kg is approximately 2.20462 lb, thus: \[ 78 \, \text{kg} \times 2.20462 \, \text{lb/kg} \approx 171.96 \, \text{lb} \] Next, we multiply the weight in lbs by the medication rate: \[ 171.96 \, \text{lb} \times 3.5 \, \text{mg/lb} \approx 601.86 \, \text{mg} \] Since we are rounding to one decimal point, the closest answer is **600.6 mg**.
