Final Answer : B, Explanation :  First, convert Rosie's weight from pounds to kilograms: 30 lb / 2.2 = 13.64 kg (approximately). Then, calculate the total daily dose: 50 mg/kg/day * 13.64 kg = 682 mg/day. Since the medication is ordered every 6 hours (which means 4 doses a day), divide the total daily dose by 4: 682 mg / 4 = 170.5 mg per dose, which rounds to 170 mg.
