1
Q

ng tube is inserted by way of the

A

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

2
Q

a gastrostomy tube is surgically placed directly into the

A

clients stomach and provides another route for administering medications and nutrition

3
Q

guidelines for admin meds in tubes

A
  • 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
4
Q

intermittent suction

A

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

5
Q

continuous suction

A

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

6
Q

fluids and electrolytes, especially potassium,

A

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

7
Q

nasogastric irrigation may require

A

a physicians order

8
Q

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

A

provides negative pressure

9
Q

alternative feeding methods to ensure adequate nutrition include both

A

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

10
Q

parenteral nutrition

A

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

11
Q

enteral nutrition

A

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.

12
Q

enteral access is acheved by means of

A

nasointesinal tubes or gastrostomy or jejunostomy tubes

13
Q

a nasogastric tube

A

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

14
Q

large bore nasogastric tubes

A
  1. levin tube- single lumen

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

15
Q

nasogastric tubes

A

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

16
Q

naso enteric tube

A

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.

17
Q

nasoenteric tubes

A

are used for patients who are at rick for aspiration

18
Q

gastrostomy and jejunostomy

A

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

19
Q

infants and NG tube

A

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

20
Q

before feedings are introduced

A

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.

21
Q

measuring PH of aspirated fluid

A

is the most recommended method to determine tibe placement

BUT THE MOST EFFECTIVE METHOD IS RADIOGRAPHIS VERIFICATION OF PLACEMTENT

22
Q

enteral feedings

A

can be given intermittently or continuously.

23
Q

intermittent feedings

A

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

24
Q

continous feedings

A

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

25
Q

cyclicl feedings are continous feedings that

A

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

higher nutrient densities and faster infusion rates

26
Q

open systems use

A

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

27
Q

feedings are admind at

A

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.

28
Q

assessing patients receiving tube feedings

A
  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
29
Q

to prevent clogged feeding tubes

A

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.
