OK so tell me fellow nurses, when you have a patient on TPN, and you are hanging a new bag - which you need to add a vial of vitamins to the TPN bag, my question is:
Which port do you inject the vitamins into - a separate "medication port" on the TPN bag OR the port on the TPN bag which you spike with the IV drip line?
I was shown how to do it and I remember told to use the medication port by one nurse, then.... I wanted to see how this other nurse hung the TPN, and she told me NO and preceeded to inject the vial of vitamins into the port in which you spike the TPN bag with. I have not had time to clarify this with the facility or pharmacy yet, but am interested in what others have to say about this.

- slowly push the plunger on the syringe, injecting the solution into the bag.
- remove the needle.
- mix the medication into the tpn solution by gently rocking the bag.
- repeat this procedure for each medication or vitamin that needs to be added.
