Order: Ampicillin 750mg im q6h

Supply: 1 gram vial of ampicillin

Directions: add 2.4 ml sterile water to yield 2.5 ml of soltuion

750 mg x 2.5 ml = 1875

1 gram = 1000 mg

D/H = 1875/1000 = 1.9 ml.

Order: Nafcillin 750 mg IM qid

Supply: Nafcillin 2 gram vial

Directions: add 6.8 ml sterile water for total of 8 ml of solution.

750 mg x 8 ml = 6000

2 gram = 2000 mg

D/H= 6000/2000 = 3 ml.

There are many methods. What matters most is understanding the question, then you can apply the method that works for you. I use DA most of the time.
