Answer :
To calculate the normal dosage range for the IV medication, we can use the information provided. The ordered medication is 50 mcg in 200 mL to infuse over 2 hours.
To determine the normal dosage range, we can calculate the dosage in mcg/hr. First, we need to find the dosage in mcg/hr by dividing the total dosage (50 mcg) by the infusion time (2 hours):
Dosage in mcg/hr = 50 mcg / 2 h = 25 mcg/hr
The normal dosage range is given as 1.5-3 mcg/hr.
Therefore, the normal dosage range for the medication is 1.5-3 mcg/hr to the nearest tenth. Since the ordered dosage is 25 mcg/hr, which falls within the normal dosage range of 1.5-3 mcg/hr, we can conclude that the dosage ordered is appropriate and falls within the recommended range.

Final answer:
The question involves calculating and evaluating a medication dose for an IV infusion. A medication dosage of 25 mcg/h is assessed and found to be within the safe range for an 11 kg child, aligning with provided dosage guidelines.
Explanation:
The student's question involves calculating the normal dosage range and the dosage being administered for an IV medication, specifically how to calculate the dosage in mcg/h for a given volume/time and assess it against a normal range. The medication in question is administered at 50 mcg in 200 mL over 2 hours. To find the dosage rate, we divide the total mcg (50 mcg) by the total hours (2 hours), which equals 25 mcg/h.
The normal dosage range given is 1.5 to 3 mcg/kg/h. However, without the child's weight, we can assess the dosage order against the standard given range. But with a specific case mentioning an 11 kg child, we can calculate the lowest and highest dosage in mcg/h by multiplying the child's weight (11 kg) by each end of the dosage range: 1.5 mcg/kg/h × 11 kg = 16.5 mcg/h (lowest) and 3 mcg/kg/h × 11 kg = 33 mcg/h (highest). Thus, the ordered dosage of 25 mcg/h falls safely within this range.
Assessing the dosage ordered against the normal range, it appears appropriate and safe for the given child's weight, sitting nicely between the lowest and highest recommended dosage levels.
