Exam 4: Nutrition Flashcards
Chyme
Liquified acidic food product
Bile
Released from liver, secretin and cholecystokinin from the small intestine
Peristalsis
Moves chyme along, gradual decreasing acidity
Digestion occurs in the
Small intestine
Primary site of absorption
Small intestine via the villi
Active transport
Higher concentration lower, carrier moves nutrient across the cell membrane
Passive diffusion
Particles move from higher to lesser concentration WITHOUT carrier
Osmosis
Movement of water across a membrane to equalize pressure
Pinocytosis
Absorbing cell engulfs large nutrients
What is needed for cell function as it depends on fluid environemtn

Dietary reference intakes
Acceptable range of quantities of vitamins and minerals for each gender and a few group
UNderstand factors associates with intake of food and fluids in each society and culture
Celebrations
Traditions
Values, beliefs, and attitudes can affect what food is purchased, prepared, and consumed
Development, body composition, activity, pregnancy/lactation, and disease can alter nutritional requirements.
Environment: what is available? Famine? Feast? Food deserts?

Decrease caloric needs r/t decreased BMR
assessment for nutrition
Age
Physical assessment:
Height, Weight (changes?), Fat Distribution, BMI Calculation
Health history/Oral health
Laboratory tests
Primary diagnosis & Comorbidities
Screening tools (e.g. Mini-Nutritional Assessment MNA)
Alternative food patterns & Patient’s general nutrition knowledge
Cultural, Religious, or Personal Food Preferences
Socioeconomic status
Psychological factors
Use of alcohol/illegal drugs
Physical signs of nutrition or malnutrition
General appearance Height/Weight Posture/muscle development/nerve conduction GI function CV function General energy Hair/Skin/Nails Lips/tongue/gum/teeth/oral membranes Eyes
Antrhopometry
measurement system of the size & makeup of the body
BMI measure
weight corrected for height & serves as an alternative to traditional height-weight relationships
Alternative food patterns based on
Religion, cultural background, ethics, health beliefs, preference
Vegetarian diets
No animal flesh for sure and consists of predominately plant foots
Ovolactovegetarian
No meat, but will ear eggs and milk
Vegan
Consumes only plant foods, no animal products at all
Less common food patterns
Lactovegetarian (no meat/eggs…does eat dairy)
Fruitarian: consumes fruit, nuts, honey, & olive oil
Zen macrobiotic: brown rice & grains, vegetables
Factors affecting nutrition include
Fluid balance/hydration Liver Function Kidney Function Digestive function Presence of disease Medications Supplements Diet choices
Lab tests for nutrition status
Hemoglobin and hematocrit
Serum Albumin
Hemoglobin and hematocrit is dependent on
Plasma volume! They are Concentration!
If a patients is hypovolemic, their hemoglobin and hemtocrit will appear
Higher than normovolemic
If a patient is hypervolemic, they will have a
Lover level of HgB and Hct
Malnutrtion affects serum albumin in
Leading to hypoalbuminemia
If albumin is depleted, free floating drug levels will
be elevated, which can lead to drug toxicities
Serum ferritin
A protein that STORES iron
Serum transferrin
an iron TRANSPORT protein
the longer the binding capacity (there is space left) the
Lower the iron levels
Absorption of drugs is ____ with food
decreased
Some foods can have what effect on drugs
Can be antidotes or deactivate medication
Some drugs are also associated with a decrease of
Certain vitamins like iron, B12, calcium, vitamin D,K etc.
Cachexia
dramatic weight loss/muscle atrophy seen in patients with chronic illness & age-associated failure to thrive syndromes
What is common in older population because of decrease sebaceous gland activity
Dry, flake, skin (Xerosis)
Mal-nutrition can have what manifestations
Spoon-shaped, brittle nails (koilonychia)
Smooth, “beefy” red tongue (glossitis)
Cracked lips, especially in corners of mouth (cheilosis)
Dull, dry, sparse hair
Poor wound healing
Pallor and pallor conjunctiva
Koilonychia
Spoon-shaped, brittle nails
Glossitis
Inflammation and swelling of the tongue in part or fully
Glossitis is a sign of what deficiency
Decrease in B complex vitamins, iron
Cheilosis
Cracked lips, especially in corners of mouth
Cheilosis is due to
Decreased iron, B complex vitamins
Heart rate and respiratory rate from someone with malnutrition
Increased HR and RR
Edema from malnutrition is due to
Osmotic shift with low albumin levels
Malnutrition can lead to what effect in extremities
Numbness, burning, tingling (paresthesia)
Malnutrition and reflexes
Decrease reflexes fur to slowed neuromuscular run, electrolyte imbalances, altered LOC
dysphaGIA
Difficulty swallowing
Dysphagia assess for
Drooling, vocal quality, head control/position, wet cough, pocketing of food, dry cough, choking, etc…
Causes of dysphaGIA
Myogenic: muscular (aging, MD, polymyositis)
Neurogenic: neurogenic (CVA, CP, MS, ALS, DM Neuropathy, Parkinson’s)
Obstructive: physical blockage (Stricture, Candidiasis, CA lesions, Inflammation, Trauma, Cervical Spondylosis)
Other: Catch-all (GI/Esophogeal resection, Rheumatalogical, Connective Tissue Disorders, Vagotomy)
changes with dysphaGIA
Dysphagia Pureed
Everything is pureed to pudding-like consistency
Dysphagia Mechanically Altered
Moist (mashed potatoes instead of rice/couscous)
Soft-textured (hamburger instead of steak, peas instead of celery)
Dysphagia Advanced
Most foods but tougher, harder, and stickier items worked into bite-sized pieces
Steak OK if cut small
Regular/General Diet
FLuid changes for dysphaGIA
Thickeners alter the consistency to make swallowing easier and safer (reduce ASPIRATION)
Thickeners are often starch or gum-based powders
Fluid consistencies
Thins
Nectar thick (apricot nectar)
Honey thick
Spoon/Pudding thick
Advancing diets
Gradual progression of dietary intake or therapeutic diet to manage illness
Oral feeding support
Involve entire team: RD, SLP, NAC, Restorative, Patient/Family, OT (what can an OT do???)
Decrease clutter and distractions (low stim)
Upright positioning imperative r/t risk of aspiration
Slow/patient feeding
Small bites
Monitor for pocketing in cheeks
Adaptive devices (built up utensils, plate guards, divided plates, special glasses/cups, long straws)
Chin tilt during swallow
Clearing throat between bites
Dignity in dining
Clients have the RIGHT, and the facility is legally required to ensure dignity in care and services. Groomed and dressed for dining Palatable foods: appearance and taste Comfortable and supportive physical environment --Tablecloths --Music --Noise control --Respectful conversations
Therapeutic diets
Clear liquid Full liquid Low residue High fiber Low sodium Low cholesterol Diabetic/Controlled Carbohydrates Gluten Free BRAT diet: bananas, rice, applesauce, toast
Malnourished patient and drug toxicity
Malnourished = decreased in albumin = free floating drugs and drug toxicity
Enteral nutrition/enteral feeding means patient has a
Functional GI tract
Enteral Nutrition/Enteral Feeding flows into
GI tract; stomach to intestines
Enteral Nutrition/Enteral Feeding is because of
Swallow issue, but still able to absorb nutrients
Parenteral nutrition (IV) is due to a
NONFUNCTIONAL GI tract
Parenteral Nutrition (Intravenous) flows into
Vascular system
Parenteral Nutrition (Intravenous) issues
Critical illness
Extended bowel rest/absorption issues
Enteral nutrition (EN): Nutrition directly
into GI tract !
Enteral nutrition (EN) is to be started
SLOW
Enteral nutrition (EN): can be … (administration)
Continuous infusion or intermittent bolus
Enteral nutrition (EN): flush formula/mesication with
H2O as ordered
Nasogastric, jejunal, or gastric tubes are
surgical or endoscopic placement
Nasogastric:
nose entry
Gastrostomy
: PEG (percutaneous endoscopic gastrostomy) stomach
Jejunostomy:
PEJ (percutaneous endoscopic jejunostomy) small intestine
Feeding tubes have a risk of
aspiration: greater w/PEG but possible with PEJ.
Remember, for tube feeding, NEVER
allow head of bed (HOB) to be flat during feedings or for at least 1 hour after.
Tube feeding: Formula can be
Aspirated into the bronchial tree and lungs
tube feeding irritation of tissue causes
Inflammation
Pneumonia
Acute respiratory distress syndrome
Sarcopenia
Specifically decrease in lean muscle mass
Tube feeding: Delayed gastric emptying is a risk for
Aspiration
For delayed gastric emptying, administer
Prokinetic medication as ordered to promote peristalsis
Measure gastric residual volumes
- -Adults: delayed gastric emptying is a concern if: ≥ 250 mL remains in stomach on 2 consecutive feedings or if > 500 mL for one feeding.
- -Smaller people tolerate lesser volumes due to smaller stomachs. Infants/children, petite adults.
