We ignore the dilution of the dextrose.
Assume the volume of injection is x ml, which contains 300mg/2ml, or 150mg/ml, or 0.15 g/ml
Volume of injection required
= 2/0.15 = 13.3 ml
Volume of D5W = 1000-x = 983.7 ml
Total volume = 1000 ml
total antibiotic = 13.3*0.15 = 2 g
A physician orders 2gms of an antibiotic to be placed in 1000ml of D5W.
Using a constituted injection that contains 300mg/2ml, how many mls should
be added to the IV solution?

On second reading, I realize that the idea is to mix a quantity of the injection into 1000 ml of D5W. This way, the volume of D5W does not have to be measured.
So simply mix 13.3 ml of injection into the bag of 1000 ml of D5W.
