A pharmacy technician receives a prescription for 18 mg/kg for an infant who weighs 10.6 kg (23.3 lb). Which of the following is the dose the technician should prepare?

To determine the dose that the pharmacy technician should prepare for the infant, the calculation involves multiplying the weight of the infant by the prescribed dosage per kilogram. In this case, the infant weighs 10.6 kg, and the prescription dose is 18 mg/kg.

The calculation is as follows:

1. Find the total dose: Multiply the weight of the infant (10.6 kg) by the dosage per kg (18 mg/kg).

[

10.6 , \text{kg} \times 18 , \text{mg/kg} = 190.8 , \text{mg}

]

It's crucial to note that when rounding, the answer here can be approximated for practical purposes, but accurately doing the math yields approximately 190.8 mg, which aligns closely with the choice presented, D.

Choosing this option as the answer indicates an understanding that multiple step calculations are often necessary in pharmacy calculations and highlights the importance of converting units correctly while also considering weight-based dosing for medications, especially in pediatrics.
