Answer 1

nasopharynx and is placed into the clinets stomach for the purpose of feeding the client or to remove gastric secretions.

Question 2

a gastrostomy tube is surgically placed directly into the

Answer 2

clients stomach and provides another route for administering medications and nutrition

Question 3

guidelines for admin meds in tubes

Answer 3

• always check with pharm if it comes in liquid form
• if they do not come in liquid form, check to see if they can be crushed
• mix shit with only pharms advice
• crush tablet into fine powder and dissolve in at least 30 ml of warm water. cold h2o causes discomfort and may not dissolve tablet.
• no bulk forming laxatives
• make sure meds are compatible with feeding solution

Question 4

intermittent suction

Answer 4

is applied whena single lumen gastric tube is used to reduce the risk of damaging the mucous membrane near the distal port of the tube

Question 5

continuous suction

Answer 5

may be applied if a double lumen tube is in place.

Question 6

fluids and electrolytes, especially potassium,

Answer 6

must be replaced intravenously when gastric suction or continuous drainage is ordered.

Question 7

nasogastric irrigation may require

Answer 7

a physicians order

Question 8

a suction regulator with a drainage receptacle connects to a wall outlet that

Answer 8

provides negative pressure

Question 9

alternative feeding methods to ensure adequate nutrition include both

Answer 9

enteral (through the gastrointestinal system) and parenteral (intervenous) methods.

Question 10

parenteral nutrition

Answer 10

involves the intravenous infusion of water protein, carbs, electrolytes, minerals, and vitamins through a central vein

Question 11

enteral nutrition

Answer 11

is provided when the client is unable to ingest foods or the upper GT is imparied and the transport of food to the small intestine is interrupted.

Question 12

enteral access is acheved by means of

Answer 12

nasointesinal tubes or gastrostomy or jejunostomy tubes

Question 13

a nasogastric tube

Answer 13

is inserted through one of the nostrils down the nasopharynx and into the alimentary tract.

Question 14

large bore nasogastric tubes

Answer 14

1. levin tube- single lumen

2. salem sump tube- allows delivery of liquids to stomach or removal of gastric contents AND suctioning

Question 15

nasogastric tubes

Answer 15

are used for patientswho have intact gag and cough reflexes, who have adequate pastric emptying, and who require short-term feedings.

Question 16

naso enteric tube

Answer 16

a longer tube than the nasogastric tube (at least 16 cm for an adult) is inserted through one nostril down into the upper small intestine.

Question 17

nasoenteric tubes

Answer 17

are used for patients who are at rick for aspiration

Question 18

gastrostomy and jejunostomy

Answer 18

devicces are used for long term nutritional support, generally, more than 6-8 weeks

Question 19

infants and NG tube

Answer 19

place infant in infant seat
measure app. NG length from nose to earlobe and then midway between umblilicus and xiphoid procces.
if an OROGASTRIC tube is inserted measure from tip of earlobe to corner of mouth to xiphoid process

Question 20

before feedings are introduced

Answer 20

tube placement is confirmed with radiography, then nurse marks the tibe with indelible ink or tape at its exit point from the nose and documents the length of visible tubing for baselline data. the nurse is resposible for checking tube placement.

Question 21

measuring PH of aspirated fluid

Answer 21

is the most recommended method to determine tibe placement

BUT THE MOST EFFECTIVE METHOD IS RADIOGRAPHIS VERIFICATION OF PLACEMTENT

Question 22

enteral feedings

Answer 22

can be given intermittently or continuously.

Question 23

intermittent feedings

Answer 23

are the admin of 300 or 500 ml of enteral formula several times per day. usu over 30 mins in the stomach

Question 24

continous feedings

Answer 24

are generally admined over 24 hours by using an infusion pump that guarantees a constant flow rate . admined in the small bowel.

Question 25

cyclicl feedings are continous feedings that

Answer 25

are admined in less than 24 hours, usu during the night.

higher nutrient densities and faster infusion rates

Question 26

open systems use

Answer 26

an open top container and should have no more than hours of formula poured into them

Question 27

feedings are admind at

Answer 27

room temp because microorgs can grow in warmed and should NOT BE HANGED LONGER THAN MANUFACTURE RECOMMENDS. feedings kept cold reduces flow of gastric juices and may cause cramps. AND TOO much heat can coagulate and irritate mucous membrane.

Question 28

assessing patients receiving tube feedings

Answer 28

1. bowel sounds before each feeding or, for continous feedings, every 4-8 hrs. (helps determine peristalsis)
2. abdominal distension
3. correct placement of tube
4. presence of regurgitation and feeling of fullness after feedings
5. diarrhea
6. urine for sugar
7. hematocrit
8. serum bun, glucose, and sodium levels (high proteinmkes kidneys not able to excrete nitrogenous wastes adequately

Question 29

to prevent clogged feeding tubes

Answer 29

flush liberally before, between and after each sep medication by using 60 ML piston syringe. The larger the barrel of the syringe the less pressure exerted. too great pressure can rupture the tube, especially small-bore feeding tubes. DO NOT ADD MEDICATIONS TO FORMULA OR TO EACH OTHER.
