A nurse is providing care to a 4-year-old child hospitalized with vomiting and suspected dehydration. The health care provider has prescribed ondansetron 0.5 mg/kg IV as a one-time dose. The safe dose is 5 mg/kg/dose. The child weighs 44 lbs. How many milligrams should the nurse administer? Round your answer to the nearest tenth if needed

Answer and Explanation

The Correct Answer is ["10"]

To calculate the dosage of ondansetron for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 44 lbs, which is equivalent to 20 kg (44 lbs / 2.2 lbs per kg). The prescribed dose is 0.5 mg/kg, so you would multiply the child's weight in kilograms by the dose: 20 kg * 0.5 mg/kg = 10 mg. Since the safe dose is up to 5 mg/kg per dose and the child's weight is 20 kg, the maximum safe dose would be 100 mg (20 kg * 5 mg/kg). Therefore, the nurse should administer 10 mg, as it is within the safe dose range.
