A nurse is preparing to administer a medication to a pediatric patient whose weight has been recorded as 18 pounds. The medication dosage is calculated as 30 mg/kg. What is the correct dosage in mg for this patient?

Step 1: Convert pounds to kilograms Formula: kg = lb ÷ 2.2 Compute: 18 lb ÷ 2.2 = 8.18 kg (rounded to 8.2 kg) Step 2: Multiply weight in kg by the dosage (mg/kg) Dosage ordered = 30 mg/kg 30 mg × 8.18 kg = 245.4 mg Step 3: Round appropriately Rounded to nearest whole number → 245 mg
