Nutritional Support of Hospitalized Patient Flashcards
what are the physiological consequences of inadequate nutrition
what does protein malnutrition cause (2)
- low muscle mass
- hypoproteinemia
what does energy malnutrition cause (3)
- reduced body weight
- loss of body fat
- low CHO stores
what are consequences of inadequate nutrition (3)
- poor tissue repair
- immune dysfunction
- altered drug metabolism
what are the consequences of inadequate nutrition
when is it necessary to intervene
- prolonged anorexia (partial or complete) for > 5 days
- anticipated ongoing inadequate food intake of > 3 days
- evidence of poor nutritional status
- concern for development of hepatic lipidosis
how is poor nutritional status (4)
- BCS <3/9
- hypoalbuminemia
- recent weight loss of >10% of body weight
- severe generalized muscle wasting
what are the risk factors for hepatic lipidosis
obestiy
inflammatory conditions
what are the types of hepatic lipidosis
primary vs secondary
what are the reasons a patient could be anorexic
- physical inability to eat?
- underlying disease process?
- nausea?
- pain?
- impaired olfaction/taste? (cats)
what are enteral nutrition options (4)
- NO or NG tube
- esophagostomy tube
- gastronomy tube
- jejunostomy tube
why is enteral nutrition preferred over parenteral if it is possible
better outomces
vili and enterocytes will get nutrition from local contents
if withholding food for a long time can lose the barrier function of the intestine and pre-dispose to infection
what are parenteral nutrition options (3)
- total parenteral nutrition (TPN)
- partial parenteral nutrition (PPN)
- peripheral parenteral nutrition (PePN)
what are contraindications of NO or NG tubes
facial traumas
what are indications for PEG tube placement (4)
- esophageal disease
- esophagitis
- esophageal stricture
- megaesophagus
