A home infusion pharmacist constitutes a vial containing 2 g of piperacillin sodium to 10 mL with sterile water for injection. The 2 g solution is then diluted by adding it to 50 mL of 0.9%NaCl injection for administration by IVPB. What is the concentration, in mg/mL, of piperacillin sodium in the infusion solution?
The answer is 33.
Homework Answers
The vial containing 2 g of piperacillin sodium to 10 mL with sterile water for injection.
The 2 g solution is then diluted by adding it to 50 mL of 0.9%NaCl injection for administration by IVPB.
It means the total solution is 60ml. (50ml of NaCl + 2 g of piperacillin sodium of 10 mL)
Now, 60ml solution contains a total of 2gm I.e 2000 mg
Then 
That means 1ml of solution contains 33 mg (in the round) of piperacillin sodium.
