Enteral Nutrition Flashcards
Used when a client cannot consume adequate nutrients and calories orally, but maintains a partially functional GI system
Enteral nutrition
NG tubes and Nasointestinal tubes are used for how long?
Short term - 3-4 weeks
Endoscopically placed and generally well tolerated by pt
PEG tube
Surgically inserted into the jejunal portion of sm intestine
Jejunostomy tubes
Preferred when long-term use is anticipated or when nasal obstruction makes insertion thru the nose impossible
Endoscopic or surgical placement of tube
Polymeric or intact formulas; composed of whole proteins or protein isolates; Require a functioning GI tract. Provide 1-1.2 cal/mL
Standard formulas
Elemental formulas; composed of partially digested protein peptides and are referred to as free amino acids; used for clients with partially functioning GI tract or for those who have an impaired ability to digest and absorb foods (i.e. IBD, cystic fibrosis). Provide 1-1.2 cal/mL, some provide 1.5-2.0 if high calorie
Hydrolyzed formulas
When should bags be discarded?
every 24 hr
Formula is administered at a continuous rate over a 16-24 hr period; recommended for critically ill clients
Continuous drip method
How often should residual volumes be measured in continuous drip feedings?
every 4-6 hr
How often should feeding tubes be flushed in continuous drip feedings?
Every 4 hr
Formula is administered a continuous rate over an 8-16 hr time period, often during sleeping hours; often used to transition from total EN to oral intake
Cyclic feedings
Formula is administered every 4-6 hr in equal portions of 200-300 mL over a 30-60 min time frame, usually by gravity drip; often used for noncritical pts, home-tube feedings, and clients in rehab
Intermittent tube feedings
Lg volume of formula (500 mL max, usual volume is 250 to 400 mL) is administered over a short period of time, usually less than 15 min, 4-6x a day; may cause dumping syndrome
Bolus feedings
Prior to instilling enteral feeding, what should be done?
Tube placement should be verified by radiography
