Correct Answer is ["0.1696"]
Explanation
To calculate the ordered dose by the physician in mg/kg/dose, we need to convert the infant's weight from pounds and ounces to kilograms. One pound is equal to 0.4536 kg and one ounce is equal to 0.02835 kg. Therefore, the infant's weight in kilograms is:
6 x 0.4536 + 3 x 0.02835 = 2.948 kg
The ordered dose by the physician is 0.5 mg IV q 2 hours prn. To find the dose in mg/kg/dose, we divide the dose in mg by the weight in kg:
0.5 / 2.948 = 0.1696 mg/kg/dose
The recommended dosage for a child is 0.1-0.2 mg/kg/dose q2-4 hours prn. The ordered dose by the physician falls within this range, so it is a safe dosage for the infant.
