A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer? (Round to the nearest tenth.)

To calculate the dose: 30 mg/kg/day x toddler's weight in kg (33 lb ├À 2.2) = total daily dose. Then divide by 2 for the 12-hour interval. Convert 5 mL of 200 mg/5 mL suspension to mg/mL (200 mg ├À 5 mL) = 40 mg/mL. Finally, divide the total daily dose by the concentration (total daily dose ├À concentration) to get the amount in mL to be administered. In this case, it would be 140 mg ├À 40 mg/mL = 3.5 mL. Therefore, the correct answer is 5.6 mL, rounded to the nearest tenth. Other choices are incorrect due to errors in calculations or not converting the dose properly.
