A 9-year-old child who weighs 66 lb is to receive gentamicin sulfate 2 mg/kg/dose every 8 hours for an Escherichia coli urinary tract infection. How many mg per dose should this child receive? (Enter numeric value only.)

Here's how to calculate the gentamicin dosage per dose for the child: Client weight conversion: Client weight: 66 lbs We need the weight in kilograms (kg) for the medication dosage. Conversion factor: 1 kg = 2.205 lbs Client weight (kg) = 66 lbs / 2.205 lbs/kg = 30 kg (round to nearest whole number) Gentamicin dosage: Prescribed dose: 2 mg/kg/dose (given) Calculate the total gentamicin amount per dose: Total dose (mg/dose) = Dose (mg/kg/dose) x Client weight (kg) Total dose (mg/dose) = 2 mg/kg/dose * 30 kg Total dose (mg/dose) = 60 mg (round to nearest whole number) Therefore, the child should receive 60 mg of gentamicin sulfate per dose.
