nutrition chapter 16 vocabulary terms

The delivery of nutrients using a feeding tube of intravenous infusions, often referred to simply as nutrition support.

specialized nutrition support

the provision of nutrients using the GI tract; usually refers to the use of tube feedings.

enteral nutrition

the intravenous provision of nutrients that bypasses the GI tract.

parenteral nutrition

nutrition care that allows a malnourished patient to meet nutritional requirements by mouth; may include oral nutritional supplements, nutrient-dense foods and snacks, or fortified foods.

oral nutrition support

abnormal passages between organs or tissues (or between an internal organ and the body's surface) that permit the passage of fluids of secretions.

fistulas

not easily managed or controlled

intractable

drawing in by suction or inhalation; a common complication of enteral feedings in which substances from the GI tract are drawn into the lungs. Aspiration risk is high in patients with esophageal disorder, neuromuscular diseases, and conditions that reduce

aspiration

units of measure for a feeding tub's outer diameter

french units

the removal of stomach contents (such as GI secretions, air, or blood) in patients with motility problems or obstructions that prevent stomach emptying

gastic decompression

enteral formulas that contain mostly intact proteins and polysaccharides; also called polymeric formulas

standard formulas

proteins that have been isolated from foods

protein isolates

enteral formulas that are prepared by using a food blender to mix and puree whole foods

blenderized formulas

enteral formulas that contain proteins and carbohydrates that are partially or fully hydrolyzed; also called hydrolyzed, chemically defined or monomeric formulas

elemental formulas

triglycerides that contain fatty acids that are 6 to 12 carbons in length. Do not require digestion and can be absorbed in the absence of lipase or bile

medium-chain triglycerides

enteral formulas for patients with specific illnesses; also called disease specific formulas or specialty formulas

specialized formulas

enteral formulas prepared in the hospital from modules that contain single macronutrients; used for people with unique nutrient needs

modular formulas

the concentration of osmotically active solutes in a solution, expressed as milliosmoles per kilogram of solvent. affect osmosis

osmolality

a formula with an osmolality similar to that of blood serum (about 300 milliosmoles per kilogram)

isotonic formula

a formula with an osmolality greater than that of blood serum

hypertonic formula

management systems that address food safety by analyzing biological, chemical, and physical hazards that may arise during the preparation, storage, handling, and administration of food products; commonly referred to as HASS-ip

hazard analysis and critical control points systems

a formula delivery system that requires the transfer of the formula from its original packaging to a wedding container

open feeding systems

a formula delivery system in which the sterile formula comes prepackaged in a container that can be attached directly to the feeding tube for administration

closed feeding system

feedings with delivery rates of about 250 to 400 milliliters of formula over 30 to 45 minutes

intermittent feedings

feedings with delivery rates of about 250 to 500 milliliters of formula over 5 to 15 minute period

bolus feedings

feedings that are delivered slowly and at a constant rate over an 8 to 24 hour period

continuous feedings

continuous feedings conducted for 8 to 16 hours daily, allowing patient mobility and bowel rest during the remaining hours of the day

cyclic feedings

the volume of formula and GI secretions remaining in the stomach after a previous feeding

gastric residual volume

the small diameter veins that carry blood from the limbs

peripheral viens

the large diameter veins located close to the heart

central veins

the infusion of nutrient solutions into peripheral veins, usually a vein i the arm or back of the hand

peripheral parenteral nutrition

inflammation of a vein

phlebitis

the concentration of osmotically active solutes in a solution, expressed as milliosmoles per liter of solution

osmolarity

the infusion of nutrient solutions into a central vein

total parenteral nutrition

a thin tube placed within a narrow lumen (such as a blood vessel) or body cavity; can be used to infuse or withdraw fluids or to keep a passage open

catheter

an anticoagulant that works by interfering with vitamin K's blood clotting function; patients using warfarin need to maintain a consistent vitamin K intake from day to day

warfarin

a parenteral solution that contains dextrose, amino acids, and lipids; also called a 3-in-1 solutions or an all-in-one solution

total nutrient admixture

a parenteral solution that contains dextrose and main acids, but excludes lipids

2-in-1 solution

continuous administration of parenteral solutions over a 24-hour period

continuous parenteral nutrition

administration of parenteral solutions over an 8 to 14 hour period each day

cyclic parenteral nutrition

a condition that sometimes develops when a severely malnourished person is aggressively fed; characterized by electrolyte and fluid imbalances and hyperglycemia

refeeding syndrome
