Chapter 5 Flashcards
Enteral and Parenteral Nutrition Support
aspiration
inspiratioin of foreign matter into the lung
bolus feeding
rapid administration of 250-500 mL of formula several times daily
central venous catheter (CVC)
vascular access device inserted into large veins such as the subclavian, jugular, or femoral veins in the center of the body
colonocyte
epithelial cell of the large intestine or colon
continuous feedings
administration of formula for 10-24 hours daily, using a pump to control the feeding rate
enteral nutrition (EN)
feeding through the gastrointestinal tract using a tube, catheter, or stoma that delivers nutrients distal to (or beyond) the oral cavity
gastrostomy
an opening into the stomach
hydrophilic
water loving, or attracting water
inplantable port
vascular access device that is completely under the skin, is placed in the vein on the upper chest wall, and exits the body near the xyphoid process, axilla, or abdominal wall
intermittent feedings
administration of formula several times daily, over 20-30 minutes
intravenously (IV)
by vein, in reference to administration of drugs or nutrients
intravenous lipid emulsion (ILE)
the type of fat that is administered as part of a parenteral nutrition solution
jejunostomy
an opening into the jejunum
nasogastric feeding tube
a tube that is inserted nasally (through the nose) into the stomach
nasointestinal feeding tube
a tube that is inserted nasally (through the nose) past the stomach into the intestine
NPO
nil per os, which is Latin meaning “nothing by mouth”
orogastric feeding tube
a tube that is inserted orally (through the mouth) into the stomach
osmolality
number of water-attracting particles per weight of water in kilograms (mOsm/kg)
osmolarity
number of millimoles of liquid or solid in a liter of solution
ostomy
an artifical opening created by surgical procedure
parenteral nutrition (PN)
administration of nutrition directly into the circulatory system (formally known as total parenteral nutrition (TPN) and intravenous hyperalimentation (IVH), which has been replaced by central parenteral nutrition (CPN)
percutaneous endoscopic gastrostomy (PEG)
a procedure used by a physician to insert a feeding tube through the skin and into the stomach using an endoscope
peripheral parenteral nutrition (PPN)
administration of nutrition into a small vein in the arm or back of the hand (also known as peripheral venous nutrition (PVN)
peripherally inserted central catheter (PICC)
vascular access device inserted into the arm and threaded into the subclavian vein to the vena cava
