wHERE DID THE 21.8 MLS COME FROM i was confused as to where that calculation came from

Savannah, the 21.8ml was the amount of drug we added, it was a separate calculation performed for that particular patient. It wasn't a part of this video, but we will (soon) have videos explaining how to calculate CRI math. This video is only about how to prepare the bag. Sorry about the confusion!

We have started adding medication with a 1 1/2 inch needle attached. We did an experiment with food coloring & realized that in larger fluid bags some of the medication gets stuck in the hub. What size needle do you recommend when adding medication to a fluid bag?

Dani, that's a great point, a 1 1/2 inch needle will make sure everything gets in there! I usually use a 1" 20g needle but make sure the needle is all the way through the stopper. If your angle is a little off your medication won't make it in the bag. You should be able to see some of the bevel of your needle in the bag.
