A two-year-old toddler who weighs 30 pounds is diagnosed with otitis media. The physician ordered the antibiotic amoxicillin 20mg/kg PO q8 h. The label reads 125 mg in 5 ml. How many millimeters will you administer?

Convert weight to kilograms: 30 lb ÷ 2.2 = 13.64 kg Calculate dose in mg: 20 mg/kg × 13.64 kg = 272.8 mg per dose Determine volume to administer: If 125 mg = 5 mL, then: (272.8 mg × 5 mL) ÷ 125 mg = 10.912 mL Round to the nearest tenth: 10.912 mL ≈ 10.9 mL
