Answer 2

Answer:

Manganese

Explanation:

Trace elements are an important part of TPN and Zinc, copper, chromium, manganese and iron mg are required.

Iron is not routinely added to TPN formulations in US because there is risk of anaphylaxis and incompatibility concerns. Some studies show that iron dextran in non-lipid-containing TPN solutions is safe.

Iron is not routinely provided in TPN mixtures. They are often not a component of commercially available trace element preparations. Currently there are no well-defined recommendations about dosage and recommendation of iron in TPN solutions and intravenous administration of iron remains problematic. There remains a risk of iron overload.

From all the options provided, there are two micronutrients given which is iron and manganese. Iron is not routinely added but manganese can be routinely added.
