For a child weighing 76 pounds, how much furosemide (Lasix) will they receive if prescribed a dosage of 6 mg/kg/d?

To determine the correct dosage of furosemide (Lasix) for a child weighing 76 pounds, it’s essential to convert the child's weight into kilograms, as medication dosages are typically calculated based on kilograms.

1 pound is approximately equal to 0.453592 kilograms. Thus, to convert 76 pounds to kilograms:

[ 76 \text{ pounds} \times 0.453592 \text{ kg/pound} \approx 34.47 \text{ kg} ]

Next, the prescribed dosage is 6 mg/kg/d. To find the total daily dose for this child, multiply the child's weight in kg by the dosage in mg/kg:

[ 34.47 \text{ kg} \times 6 \text{ mg/kg} \approx 206.82 \text{ mg} ]

Since medication doses are typically rounded, the closest standard dose to the calculation (206.82 mg) would be rounded to 210 mg, as indicated in the correct answer.

Thus, the dosage of 210 mg reflects an appropriate calculation based on the child’s weight and the prescribed dosage, making it accurate for clinical use.
