Answer: Yes, doctor's order is within the desired range.

Step-by-step explanation:

We need to first convert 19.8 lb to kg.

We know that 1 kg=2.20 lb

Therefore, the weight of infant=[tex]19.8\div 2.2=9\ kg[/tex]

Minimum Desired Dosage)[tex]=9\times75=675\ mg[/tex]

Maximum Desired Dosage [tex]=9\times150=1350\ mg[/tex]

Since there are 24 hours in one day and the medication is ordered every 8 hours.

[tex]\\\Rightarrow24\div8=[/tex] 3 times per day doctor ordered medication .

Total amount of Rocephin in a day[tex]=3\times250=[/tex]750 mg ordered per day

And 750 mg is within the desired range of 675-1,350 mg

So, yes doctor has ordered a dosage within the desired range.
