ml of formula/24 hrs a day = ml per hour
Oral, enteral, & parenteral methods of nutrition support are not... ANS mutu...
3. PEM, severe wasting, or depressed growth (fail to thrive, anorexia, cachexia)
how to assess P.O. intake ANS record amount of meals from nurses
observe meal trays
enteral nutrition tube placement depends on: ANS 1. anticipated length of time for feeding
2. risk for aspiration/tube displacement
,3. planned surgical intervention
4. presence of normal digestion and absorption
nasoenteric route for enteral nutrition access ANS short term (up to 3-4 weeks); if longer needed,
can cause complications & should be changed to PEG/gastrostomy/jejunotomy tube
nasogastric: used when pt has normal GI fxn & gag reflex; bolus, intermittent, or continuous
infusions
nasoduodenal/nasojejunal route: used for gastric motility disorders, esophageal reflux, persistent
N&V
potential complications of nasal tubes ANS - Nasal irritation and erosion
- Rhinorrhea, sinusitis
- Pharyngeal or vocal cord paralysis
- Esophageal strictures
- Gastroesophageal reflux resulting in aspiration pneumonia
- Incorrect position of the tube leading to pulmonary injury
- Mucosal damage at the insertion site

enteral formula to use if Pt has malabsorption ANS elemental formulas with small peptides and
MCT oil
composition of standard polymeric enteral formulas ANS lactose free
1-1.2 kcal/ml
balanced macros
concentrated formula: 1.5-2 kcal/ml for fluid restriction, osmolality is 300-500 mOsm (used when
need more cals or have fluid restrictions)
composition of high-nitrogen enteral formulas ANS 18-25% of calories from protein
