Confused nursing student please help

Hi everyone,

I have an OSCE/CSA coming up soon and I just had a quick question. (Instructor is on leave can’t ask them) With cefTRIAXONE 2g, the injectables handbook says it must be given via IV infusion and reconstituted with approximately 40ml of a compatible fluid. In my instructors demo video, he shows himself adding it to a 100ml saline bag. Is this right? There are no 40ml saline bags are there?Would it still be given over 30 minutes? Sorry if this is confusing, I’ve added a screenshot of the page in the handbook.

Thank you!!
