Reconstituted medication problem

Published

I am so confused on how to do problems like this: PLEASE HELP!

The order reads: Acyclovir 0.25 g IVPB now. The medication comes in a vial that contains 1000 mg.

The label directions read: reconstitute with 20 mL of diluent for a solutions that contains 50 mg/mL.

The medication will be added to 100 mL D5W for IVPB infusion.

How many milliliters of reconstituted medication will the nurse add to the 100 mL bag for infusion? (fill in your numerical answer in the space provided)

1) Check your chemistry book or pharm book for equivalents.

1000mg = ? g

0.25g = ? mg

2) Look at what your question tells you

When you reconstitute the med, how many mg / cc is in the vial?

3) If you have that many mg/cc, how many cc/s will make up your desired dose?

OK so 50mg/ml of medication

We need 250mg=.25g

So 50mg x 5ml =250mg/5ml

So we need to use 5ml of reconstituted medication. This week total 105ml ivpb.

Does this make sense?
