Final answer:
No medications should be hung with a TPN bag due to risks of incompatibility and infection. If necessary, medications should be administered through a separate intravenous site or lumen. Consultation with pharmacists and adherence to hospital guidelines is critical.
Step-by-step explanation:
Generally, no medications should be hung with a TPN (Total Parenteral Nutrition) bag due to the risk of incompatibility and infection. Total Parenteral Nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract. Fluids are given into a vein to provide most of the nutrients the body needs. The solution is highly concentrated and requires a central venous catheter.
Adding medications can lead to precipitation, destabilization of the emulsion, or growth of microorganisms. If there's an essential requirement for administering a medication concurrently with TPN, it should be given through a separate lumen of the central venous catheter, or if possible, through a different intravenous site altogether. Strict protocols are in place to prevent complications that may arise from drug-TPN interactions.
