A nurse is preparing to administer azithromycin oral suspension 10 mg/kg/day to a 15-month- old infant who has otitis media. The infant weighs 22 Ib. The amount available is azithromycin oral suspension 200 mg/5 mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

- Convert the infant's weight from pounds to kilograms: 22 Ib / 2.2 = 10 kg - Calculate the daily dose of azithromycin: 10 mg/kg/day x 10 kg = 100 mg/day - Calculate the volume of azithromycin oral suspension needed: 100 mg/day / (200 mg/5 mL) = 2.5 mL/day - Round the answer to the nearest tenth: 2.5 mL/day - The nurse should plan to administer 2.5 mL of azithromycin oral suspension to the infant.
