An elderly patient weighs 150 lbs . The Physician orders medication to be administered at \( 10 \mathrm{mg} / \mathrm{kg} \). How many mg will this patient require? Select one: 581.8 681.8 651.8 628.8

To determine the medication dosage for the elderly patient, we first need to convert their weight from pounds to kilograms. Since 1 kg is approximately 2.2 lbs, we can calculate their weight in kilograms: \[ \text{Weight in kg} = \frac{150 \text{ lbs}}{2.2 \text{ lbs/kg}} \approx 68.2 \text{ kg} \] Now, using the prescribed dosage of \( 10 \text{ mg/kg} \): \[ \text{Total dosage} = 68.2 \text{ kg} \times 10 \text{ mg/kg} = 682 \text{ mg} \] Therefore, the nearest available option is **681.8 mg**.
