Final answer:
When administering TPN/PPN, it is important to check the bag both before and after administration to ensure patient safety and prevent complications.
Step-by-step explanation:
When administering TPN/PPN, it is important to check the bag both before and after administration. This is to ensure that the correct solution is being infused and that there are no visible signs of contamination or damage to the bag.
Before administration, you should check for proper labeling, expiration date, and clarity of the solution. After administration, you should double-check for any signs of leakage, discoloration, or particulate matter that may have developed during the infusion.
Regularly checking the bag is crucial to patient safety, as any issues discovered before or after administration can be addressed promptly to prevent complications.
