Nutrition support is a therapy that crosses all ages, diseases, and conditions as health care practitioners strive to meet the nutritional requirements of individuals who are unable to meet nutritional and/or hydration needs with oral intake alone. Registered dietitian nutritionists (RDNs), as integral members of the nutrition support team provide needed information, such as identification of malnutrition risk, macro- and micronutrient requirements, and type of nutrition support therapy (eg, enteral or parenteral), including the route (eg, nasogastric vs nasojejunal or tunneled catheter vs port).
