Question

Azithromycin (zithromax 0.45 gm ivpb is prescribed for a client with gonorrhea who is unable to tolerate oral medications. the medication is available in powdered form in a vial containing 500 mg. instructions indicate that the medication must be reconstituted with 4.8 ml of sterile water and that the powdered medication displaces 0.2 ml. what volume of reconstituted medication should the nurse add to the intravenous piggyback solution? record your answer using one decimal place. ___ ml

Answer 1

To prepare the IV piggyback solution, the nurse should add 4.5 ml of reconstituted azithromycin to the solution, based on the proportion of the prescribed dose to the total available medication in the vial after reconstitution.

Step-by-step explanation:

To calculate the volume of the reconstituted azithromycin medication to be added to the intravenous piggyback solution, we need to first understand the total volume of the medication after it has been reconstituted. According to the instructions provided, the medication must be reconstituted with 4.8 ml of sterile water, and the powdered medication displaces 0.2 ml. This means the total volume of reconstituted medication is 4.8 ml + 0.2 ml = 5.0 ml.

Now, we must determine how much of this 5.0 ml reconstituted solution contains the prescribed dose of 0.45 gm (450 mg). The vial contains 500 mg of azithromycin, which is now in a total volume of 5.0 ml. To get the prescribed dose of 450 mg, we can set up a proportion:

500 mg : 5.0 ml = 450 mg : X ml

Solving for X gives:

X ml = (450 mg * 5.0 ml) / 500 mg = 4.5 ml

This means that the nurse should add 4.5 ml of the reconstituted azithromycin medication to the IV piggyback solution.

Answer 2

give 0.45ml of medication
