Nutrition and GI skills care Flashcards
Assessment of nutrition of GI
Nutritional screening
- 25% of adults in hospitals are malnourished after being there for a couple of days
- Higher risk for pressure ulcers, dehydration, constipation, etc.
Nutritional assessment
- Assessments are usually done by dietitians
Patient preferences
- Important as a RN to know
- Ask what they prefer
Lab values
- Important nutritional assessment
- example: Albumum
Physical assessment
Phases of swallowing
1) Oral
- Food taken into mouth and stimulated different sense
- Creates a ball called a bolus
2) Pharyngeal
- Bolus arrises in throat and triggers swallowing reflex
- Glottic closes and allows passage into esophagus instead on airway
3) Esophageal
- Passage of bolus from esophagus to stomach due to sphincter
Dysphagia
Impairment in any stage of the swallowing process
often neurological disease such as stroke, etc
Aspiration
- Fluids or bolus go down wring tube into lungs instead of stomach
Silent aspiration
- Don’t show signs/symptoms of aspiration while it’s occurring
Possible symptoms of dysphagia and aspiration
- Coughing during meals
- Hoarse voice following meals
- Drooling
- Upper respiratory infection
- Pneumonia
Symptoms of aspiration pneumonia
- Fever
- Hear crackles when listening (coarse or fine) and hear when patients have a lower lobe pneumonia
- Dullness when percussing lungs; consolidation in lungs
- General malaise, feeling really horrible
Safety during feedings
- Positioning – upright 90 degrees
- Flex neck for ‘chin-down’
- Avoid rushing
- Alternate solid & liquid boluses
- Place food in stronger side of mouth
- Mechanically-altered diets -determine food viscosity best tolerated
- Minimize use of sedatives and hypnotics
- Minimize distractions
- Adaptive equipment if client is able to feed self
- Oral hygiene
Safety after feedings
- Positioning – patient should remain upright for 30 minutes
- Check for pocketing of food
- Note and document intake
- Note any foods that are preferred
- Note any foods the patient has difficulty with
- Oral hygiene
Therapeutic diets and mechanically altered diets
- Regular
- Mechanically altered such as soft diet
- Pureed diet
- Full liquid, clear liquid
- Low sodium
- No added salt
- High protein
- Therapeutic diets aren’t really realistic once someone has left the hospital
Thickened fluids diet
Thin - no alteration
Nectar like - slightly thicker than water, like unset gelatin
Honey like - a liquid with the consistency of honey
Pudding like or spoon thick - a liquid with the consistency of pudding
Enteral nutrition
- Nutrients provided through the GI tract distal to the oral cavity via a tube, catheter, or stoma
- Also called gavage or enteral tube feeding
Indications for enteral nutrition
- Client unable to ingest food but can still digest and absorb nutrients
- Can be for a variety of reasons
Types of entral access tubes
1) Nasal or oral insertion
- Nasogastric tube (Levin or Salem sump)
- Nasogastric or nasointestinal tube – small bore feeding tube (Keofeed/Dobbhoff)
- Orogastric or orointestinal - small bore feeding tube (Keofeed/Dobbhoff)
2) Surgical insertion
- Gastrostomy (G-tube)
- Jejunostomy (J-tube)
3) Endoscopic insertion
- PEG (percutaneous endoscopic gastrostomy)
- PEJ (percutaneous endoscopic jejunostomy)
Insertion of a nasogastric (NG) tube
- Measure from tip of nose to earlobe and to the tip of the xyphiod process
- Want end to reach the stomach
- If not far enough risk of aspirating and going into trachea
- Not a sterile procedure; but want to wear gloves and mindful that can elicit gag reflex and potential for vomiting
- Sit them up; encourage them to drink water if possible during insertion
Small-bore enteral feeding tube
- Often starts with thicker tube; if need feeding over period of time more to smaller one for more comfort
- Don’t want them to get blocked
Insertion of enteral tube: surgical or endoscopic insertion (PEG/PEJ)
- Light swallowed to guide insertion into the abdominal wall
- Comes in difference sizes in the French; starts small and advance in sizes going up
- Balloon on end to prevent falling out
Verifying tube placement
- Radiographic assessment - gold standard - before initiating feeding or medication administration
- pH testing of gastric aspirate
- Capnography- detecting expired CO2 by attaching device to end of tube
- Note respiratory distress – may not be reliable
- Aspiration of stomach contents; no longer recommended
- Auscultation; no longer recommended
- Has to be performed every time a tube is inserted, and before the first feed
Checking tube placement: pH testing
- Draw contents up with syringe through tube
- pH lower than 5 suggestsgastric placement
- pH higher than 5 may indicate intestinal or respiratory placement
Care of the patient with an NG tube
- We never lay the patient down flat; try hard to avoid
- Having them sit up at least 30 degree is important; some patients that’s not enough and has to be higher
- Leave them up for 30 minutes minimum before changing positions (post-feeding)
- Tape can be placed to anchor tube; ensure it’s clean dry and intact
- Skin around nares is dry, clean, intact
- If attached to face; well anchored, skin integrity
- Where it should be coming out of the nose; checking before feeding
- Making sure you flush the tube; (i.e. order: flush tube with 30mL of water before and after med administration)
- Remember some medications cannot be crushed; may clog up the tube, finely crush as possible when applicable
- Ensure tube is clear; give with water
- If no contraindication about fluid and water intake; be mindful of giving more water (most people in hospital are dehydrated)
- Certain types of tubes that get clogged need to go back to surgery to unclog
Administering enteral feeding
1) Bolus feeding
- Community/home settings
- Give however much food goes into and drain into stomach
- Have to work up to it
2) Intermittent
3) Continuous
Kangaroo system – has food in one contain and water for flushing in another and machine dolls it out
- Many other machines only have one feeding and you have to flush
How to unclog a tube
- Bicarb products
- Warm water
- Coca-Cola
- Be careful with using smaller syringe; increase PSI and can damage tip of tube and break it
- Some tubes if clogged have to be surgically removed
