When inserting a NG tube what would you check and why?
The physicians order and determine the type, size, and purpose of the NG tube.
If the physician did not order a specific size what is generally standard used?
16 or 18 french- adult
children can vary from a very small size 5 french to a size 12 french for older children.
What tubes may require insertion by a physician?
Larger NG tubes that are 20 to 30 french
enteric tubes such as:
How is the cantor and miller-abbott tube made and what is the purpose of thes tubes?
they are quite large and have mercury, air or fluid filled bags attatched to the distal end of the tube, the purpose of the bag is to advance the tube with peristaltic waves with the therapeutic intent of breaking up intestinal blockages.
What should you do when setting up a tube feeding equipment or suction equipment?
make sure it functions properly.
( Be sure the equipment is at the right flow or strength of suction befor using it, Dr may order a specific type of NG tube such as Levin for short term use for gavage (forced feedings) or lavage (therapeutic irrigation), or Salem sump with it two lumens generally used for lavage and gastric suctioning, or a silicone type tube used for long term placement)
You should not explain the NG tube procedure to far in advance because the client anxiety about the procedure may interfere with its success. (T/F)
How should the client be positioned in ordered to insert a NG tube?
Full fowlers if possible- this assists the client to swallow and promotes peristalsis
How do you measure the length of the tube that will be needed to reach the stomach?
Measure from tip of nose to the ear then to the xiphoid process and mark the spot with a piece of tape.
Why should you clean the face and nose befor taping the NG tube?
the NG tube will stay more secure if taped on a clean non oily nose. if the nose has been cleaned with an alcohol wipe the tape will stay more secure and the tube will not move in the throat which could cause a gagging reflex later.
The blocked nasal passage may be totally occluded but its possible to still pass a NG tube through it. (t/f)
What can be done prior to having a NG tube done to reduce the gag reflex?
hold ice chips in the mouth for a little while and the physician can also use a numbing nose spray
When inserting a NG tube how should the head be positioned?
Head flexed forward while tilting the tip of the nose upward
By asking the client to swallow this allow for a better chance of what when inserting the NG tube?
a better chance of passing into the stomach instead of the trachea
Stimulating the gag reflex is normal but asking client to swallow will do what?
minimize the gag reflex
If couging, persistant gagging, cyanoisis, or dsypnea occurs what should you do when inserting the NG tube?
remove the tube imediately the tube may be in the trachea
If obstruction is felt when inserting NG tube what should you do?
Pull tube out let client rest and try in the other nostril
you can place a temporary piece of tape across the nose to hold the NG in place while you check for placement also you should check the back of clients throat. (t/f)
What are the ways to check for placement of the NG tube?
Aspirate stomach contents- contents should appear cloudy, green, tan, off-white, bloody, or brown ( sometimes its hard to distinguish between stomach contents and respiratory aspirates.)
Check pH of aspirate- this is considered more accurate than visual inspection. pH should be in the range of 0-4 commonly less than 4 (respiratory is usually a 7 or more)
Inject 30mL of air into the stomach and listen for a whoosh sound
Xray- this is the only method that is considered positive
Always confirm placement of tube befor what?
medications, application of suction, or instillation of tube feedings
What should you do when preparing a formula?
shake can thoroughly and check expiration date, if formula is powder form mix according to instructions this type of formula can only be used for 24 hours befor it spoils and should be refrigerated although befor using the formula it must reach room temp
Befor administering a tube feeding what should you do?
determine placement of feeding tube by either:
1. aspirating stomach secreations
attach syringe to end of feeding tube
gently pull back on plunger
measure amount of residual fluid
return residual to stomach via tube and continue with feeding if amount does not exceeds agency protocal
2. injecting 10 to 20mL of air into tube (3-5mL for children)
attach syringe filled with air to tube
inject air while listening with stethoscope over left upper quadrant
3. measuring the pH of aspirated gastric secretions
4. take an xray
If using a syringe to do a feeding how high do you raise the syringe?
12 to 18 inches above the somach
When using a pump to administer feeding how often should you stop it?
every 4 to 8 hours and assess the residual. you should flush it every 6 to 8 hours
