A child who weighs 44 pounds with otitis media receives a prescription for azithromycin 10 mg/kg once, then 10 mg/kg daily for 4 days. The medication is available in a solution containing 200 mg/5 mL. How many mL should the nurse administer on the first day of the treatment regimen? (Enter numeric value only.)

Convert the child's weight from pounds to kilograms: Weight (kg) = Weight (pounds) / 2.2 pounds/kg = 44 pounds / 2.2 pounds/kg = 20 kg Calculate the prescribed dose for the first day: Dose on day 1 (mg) = Initial dose (mg/kg) x Child's weight (kg) = 10 mg/kg x 20 kg = 200 mg Calculate the volume to administer on the first day: Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL) = 200 mg / (200 mg / 5 mL) = 5 mL
