Answer 1

The correct daily dosage of Vancocin for a child weighing 90 lbs is approximately 408 mg per day, using the formula 10mg/kg/day.

Step-by-step explanation:

To calculate the daily dose of Vancocin for a child who weighs 90 lbs, we use the prescribed dose of 10mg/kg/day. First, convert the child's weight from pounds to kilograms, knowing that 1 lb is approximately 0.453592 kg. Therefore, 90 lbs is equivalent to 90 * 0.453592 = 40.82328 kg. Next, calculate the daily dosage by multiplying the child's weight in kilograms by the dose per kilogram: 40.82328 kg * 10 mg/kg = 408.2328 mg/day.

For practical purposes, the dosage is usually rounded to the nearest whole number. Thus, the correct daily dosage of Vancocin for the child is approximately 408 mg per day, which corresponds to option 1). This dosage ensures that the child receives an adequate amount of medication for their body weight to effectively treat their condition.
