A nurse is preparing to administer amoxicillin 30 mg/kg/day divided doses 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 every 12 hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the dose for the toddler, first convert the weight from pounds to kilograms (33 lb ├À 2.2 = 15 kg). Then, calculate the total daily dose (30 mg/kg/day x 15 kg = 450 mg/day). Divide this total by 2 for the dose every 12 hours (450 mg/day ├À 2 = 225 mg). Next, determine how many mL of the suspension are needed to deliver 225 mg of amoxicillin. Since the suspension is 200 mg/5 mL, you would administer 225 mg ├À 200 mg = 1.125 mL every 12 hours. Rounding to the nearest tenth, the answer is 1.1, which when rounded to the nearest tenth is 5.6 mL. Choice B is correct because it provides the accurate dosage based on the weight and concentration of the suspension. Choices A, C, and D are incorrect as they do not accurately calculate the dosage needed for
