A pharmacy technician receives a prescription for 9 mg/kg for an infant who weighs 9.6 kg (21.1 lb). Which of the following is the dose the technician should prepare?

To find the correct dose for the infant, the dose per kilogram must be multiplied by the infant's weight in kilograms. The prescription indicates a dosage of 9 mg for each kilogram of the infant's weight. Given that the infant weighs 9.6 kg, the calculation is as follows:

9 mg/kg × 9.6 kg = 86.4 mg.

This calculation leads to the conclusion that the dosage to prepare for this infant is 86.4 mg. Selecting this option ensures that the technician is administering the precise amount specified in the prescription, based on the infant's weight. This is crucial for proper medication management, especially in pediatric patients, where dosages can often vary significantly based on their body weight. The other options reflect either incorrect calculations or doses that do not align with the specified mg/kg requirement.
