Explain indications for using parenteral nutrition and list several conditions that would require parenteral nutrition instead of enteral nutrition

Answer 1

Parenteral nutrition is indicated in those clinical situations where the patient is unable to meet nutritional needs either by an oral diet or through the use of enteral nutrition. The clinical conditions that may require parenteral nutrition include an inability to digest and absorb nutrients, such as in massive bowel resection or short bowel syndrome; intractable vomiting, as in hyperemesis gravidarum; GI tract obstruction;impaired GI motility; and abdominal trauma, injury, or infection. Nutrition diagnoses associated with candidates for PN are the same as those for EN.
