Calculation
A child who weighs 44 pounds with otilis 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/5mL. How many mL should the nurse administer on the first day of the treatment regimen? (Enter numeric value only.)
mL
Explanation & Rationale
Given Information: Child's weight: 44 pounds Prescribed dose on the first day: 10 mg/kg Medication concentration: 200 mg/5 mL Convert weight to kilograms 1 pound is approximately 0.453592 kilograms 44 pounds x 0.453592 = 20 kilograms (approximately) Calculate the total dose for the first day Total dose = Prescribed dose x Weight Total dose = 10 mg/kg x 20 kg = 200 mg Calculate the volume to be administered Volume to be administered = Total dose / Concentration Volume to be administered = 200 mg / 200 mg/5 mL = 5 mL
