The package insert for the label in Figure 9.32 states: Add 3.2 mL of sterile water for injection to yield 375 mg/mL (250 mg ampicillin and 125 mg sulbactam/mL).

Answer 1

4 ml / dose

1 ml = 250mg Ampicillin+ 125mg Sulbactum

so 4 ml has to be administered at a time to deliver the required dosage and a total of 16 ml / day in 4 divided doses.

Once the powdered form of the injection will be diluted with 3.2 ml water it becomes 4 ml.
