Parenteral nutrition is the feeding of nutritional products to a person intravenously, bypassing the usual process of eating and digestion. It is used to help people who can't or shouldn't get their core nutrients from food; the person receives nutritional formulae that contain nutrients and dietary minerals. Test your understanding on this by taking the quiz below.
