Week 4: Alteration in Nutrition Flashcards
Factors that affect nutrition
- Insufficient intake of nutrients
- Altered ability to use ingested nutrients
- Increased metabolic demand
What are some examples of altered ability to use ingestied nutrients?
dentures
do they have physical access to food
disease processes impairing client ability to maintain nutriting like ulcerative colitis and chrons disease
Nursing Interventions for Altered Nutrition
Assess for s/s of malnutrition
Monitor oral intake/calorie count
Dietary Consuly
Speech Consult (Swallow eval)
Small, frequent meals
Encourage significant other to bring in fav foods and be present during meals
Manage enteral and parenteral nutrition
What are two very important things to view in the lab results regarding altered nutrition
Albumin and Prealbumin Levels
Albumin levels indicate long term pt protein levels
Prealbumin indicates short term pt protein levels
What is an example of something that may make the pt. not want to eat that is not N/V
Metallic taste in their mouth from their medications
Examples of Diets
NPO Clear Liquid (No Residue) Full Liquid Thickened Liquid SOft or Pureed Restrictive and Therapeutic Diets
Examples of what can be eaten on a clear liquid diet
apple juice
tea
broth
Examples of what can be eaten on a full liquid diet
ice cream
creamed soup
pudding
Why have a thickened liquid diet
to prevent choking and aspiration
Why have a soft or pureed diet
it is easier to chew
examples of Restrictive or therapeutic diets
NAS
Cardiac
Renal
Diabetic
High Fiber
Low Residue
Low Cholesterol
What other things can be included in diet/feedings other than the type of diet itself?
Nutritional supplements (ensure, boost)
enteral feeding (osmolite, jevity)
parenteral feedings (PPN, TPN)
Paretneral Nutrition
nutrition via an IV
Enteral Nutrition
nutrition via a tube
GI Intubation
suction or feeding via a tube that can be made of many materials like rubber or polyurethane
the tubes are variable in insertion size, length, and lumen amount
What is GI tube size (diameter) measured in
French
The larger the french size…
the longer the tube
Gastric Salem Sump tubes have ___ lumen
2
GI tubes are measured in what unit
centimeters
Most GI tubes are radiopaque, why?
So they can be visualized on X Ray
Reasons for doing GI Intubation
Decompression
Aspiration
Lavage
Administer
Diagnose
The most common reason for GI Intubation is ___
decompression
Decompression GI Intubation
Removing gas or fluid build up (removed often from bowel obstructions or can be used to control GI bleeding or prevent emesis (N/V))
Decompression tubes will need…
to be hooked to the wall for suction
Aspiration GI Intubation
removal of substances by suction
often done to obtain a specimen of gastric content
Lavage GI Intubation
A way to wash out or cleanse the stomach - having your stomach pumped is an example and it can remove any toxic substances
Administration GI Intubation
Used to give medications or tube feedings
Diagnosis GI Intubation
GI tubing and system can be intubated in order to use an endoscope or other method to diagnose a GI disorder
You would use a tube no larger than ___ french for tube feedings. Why?
12 French
You do not want to feed too fast and at the volume a feeding tube does it may be too much at once so the french should be smaller or equal to 12
Orogastric Tube
Tube inserted through the mouth into the stomach
Nasogastric Tube
NG Tube
Tube inserted through the nose into the stomach
The end point for an orogastric and nasogastric tube is the ___
stomach
Gastric tubes are often inserted where
In the ER, ICU, or post short term surgery
What is compromised when using an orogastric or nasogastric tube
The Lower Esophageal Sphincter
This leads to it always being kept open so pt is at risk for aspiration and gastric irritation from gastric fluids if they get into the esophagus
Levin Tube has ___ lumen
1
Salem Sump Tube has ___ lumen
2
Dobhoff Tube has __ lumen
3
How does the Dobhoff tube differ from the levin or salem sump
it is much longer so it bypasses the stomach and goes right into the intestines
Never inject anything into what area of a tube
the blue port
Why do some tubes have more than 1 lumen with air potentially going through them?
Ex: Salem Sump
If there is air going through it it will stop the tube from sticking to the stomach wall
Dobhoff Tube
a longer enteral feeding tube that goes all the way to the intestines
it has a weighter tungsten tip and a guide wire for placement
are often placed in a fluoroscopy lab and a provider is there helping get the tip to where it needs to be
3 lumen
What is the reason behind enteric tubes likenasoduodenal tubes, nasojejunal tubes, gastostomy tubes, and jejunostomy tubes?
Provide nutrients (tube feedings) fluids, and medications
Nasoduodenal Tube
Goes through the nose to the duodenum
Nasojejunal Tube
goes through the nose to the jejunum
What is the nurse’s role during intestinal tube placement
NOT to place or remove intestinal tubes, but to assist in insertion at GI lab and fluoroscopy
Why are intestinal tubes like nasoduodenal and Nasojejunal tubes often not useable for 24-48 hours?
the doctor will place it at the tip of the stomach adn allow peristalsis to take the tube the rest of the way to the location
Naso-tubes are often short term (__ weeks)- while long term more likely uses ___ or ___
4 weeks; gastostomy or PEG tubes
Enteral nutrition longer than ___ weeks needs a long term enteral feeding option
4 weeks
What are some examples of long term enteral feeding tubes
Gastrostomy
Jejunostomy
PEG Tube
Gastrostomy/Jejunostomy are made via what
intrabdominal surgery requiring anesthesia where the stomach wall is brought to surface, a tunnel is made, and a permanent stoma is created (in jejunostomy its the jejunum coming to surface)
PEG/PEJ Tube
This long term enteral feeding establishes a mean to provide nutrition to the patient to the abdominal wall WITHOUT intra-abdominal surgery
It is done via endoscopic procedure (Percutaneous endoscopic gastrostomy or jejunostomy)
How does the provider make the PEG/PEJ Tube
Provider goes through the mouth down to the esophagus and stomach and out through the abdominal wall through the stomach and makes an outlet where a tube is then inserted for feeding
What are some common risks/nursing diagnosis for PEG and Ostomies
Invasive Procedures
Risk for Bleeding
Risk for Infection
What is important to note about the tube of a PEG/PEJ compared to an ostomy
the PEG/PEJ has not created stoma, so if the tube is removed you have to call the provider immediately since the hole can close in 4 hours !
What are some example nursing diagnoses for enteral nutrition
imbalanced nutrition: less than body requirements
risk for infection r/t presence of wound and tube
risk for impaired skin integrity at tube insertion site
disturbed body image r/t presence of tube
What is some example objective/subjective data to gather for nutritional assessment/enteral feeding
lab work (albumin)
mucosa moist or not
dehydration
BMI < height and daily weights
I&O
regular diet - is this normal, how many times a day do you eat, nutrition (mouth to butt)
bowel movements
VS
WBC
assess sites and drainage with COCA REEDA
yeast infection risk from dark moist tube inside
Goals for Altered Nutrition and Enteral Feeding
achieve nutritional requirements
prevent infection
maintain integrity
adjust to body image
prevent complications
How often should a feeding tube be cleansed
every shift at least
Upon evaluation, what nutritional aspects should be looked at
attain weight
do they tolerate tube feeding
bowel movements
normal plasma protein level
glucose
V&M
electrolyte balance
Parenteral Nutrition
nutrients via IV
When is parenteral nutrition used
when the GI tract is not working (or post abdominal aortic aneurysm or other traumatic GI region repair for 5-7 days)
How many liters do TPN/PPN bags usually have
1-3 L of fluid
Why is TPN fluids often covered
because they need to not be exposed to light
How long is TPN/PPN run for and when are fat emulsions or lipids infused?
Run over 24 hours; fat emulsions or lipids are infused simultaneously but not for 24 hours
Central Method of Parenteral Nutrition
Central line or PICC for TPN
Peripheral Method of Parenteral Nutrition
Peripheral IV access
What is important to keep in mind when using the peripheral method rather than central for TPN/PPN
If TPN is done peripherally, DEXCTROSE LESS THAN 10% must be used because the higher dextrose can cause phlebitis that only works centrally
This is also a major reason why central is preferable
How long is peripheral parenteral access compared to central
Peripheral = short term - 5 to 7 days or as short as 3
Central can be good for up to 6 weeks
How long can PICC lines stay in for
60 months to a year - it is a port that can be under their chest wall for life
What are some indications for TPNO
Insufficient oral or enteral intake
Impaired ability to ingest or absorb food orally or enterally
Patient unwilling or unable to ingest adequate nutrients orally or enterally
prolonged preoperative and postoperative nutritional needs
What is important to do before giving PN infusion
check for “cracked solution” which is separation with an oily appearance or precipitate appearing as white crystals - if present do not use
Nursing Diagnoses for parenteral nutrition
imbalanced nutrition - less than body requirements related to inadequate oral intake of nutrients
risk for infection related to contamination of the central catheter site or infusion line
risk for imbalanced fluid volume related to altered infusion rate
risk for activity intolerance related to restrictions because of the presence of IV access device
