Question

A physician orders AMPICILLIN 500 mg to be added to 50 mL of

fluid. The available AMPICILLIN is 2 g/10 mL after reconstitution.
How much of the reconstituted AMPICILLIN should be added to the 50
mL ba

Answer 1

To prepare the requested 500 mg dosage of Ampicillin in 50 mL of fluid, 2.5 mL of the reconstituted Ampicillin (2 g/10 mL) should be added to the bag.

Step-by-step explanation:

The question asks us to calculate how much of the reconstituted Ampicillin solution should be added to a 50 mL bag to achieve a total dosage of 500 mg. We are given that the available Ampicillin is 2 g/10 mL after reconstitution. To find the volume needed to get 500 mg, we first convert 2 g to mg, which gives us 2000 mg (since 1 g = 1000 mg), and then set up a proportion to solve for the volume required.

Solution:
2000 mg is in 10 mL
500 mg is in X mL
Using cross-multiplication, we get:
2000 mg * X mL = 500 mg * 10 mL
X = (500 mg * 10 mL) / 2000 mg
X = 2.5 mL
Therefore, 2.5 mL of reconstituted Ampicillin should be added to the 50 mL bag.
