M.J. Bailey
Nutrition
Nutrition is an important treatment in any illness.Type 2: non-insulin –dependent diabetes.
Mellitus (NDDM). Mild hypertension.
Proper intake of food is essential for optimal health during illness & healing of wounds. The body needs nutrients at these times.

M.J. Bailey
Factors Influencing Dietary Patterns
1. Health status A good appetite is a sign of health Anorexia is usually a sign of disease or side
effect of drugs Nutritional support is an essential part of
recovery from medical treatment
![Page 4: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/4.jpg)
M.J. Bailey
Factors Influencing Dietary Patterns
2. Culture and religion. Culture, ethnic, and religious patterns and
restrictions re food must be considered. Special foods and diets given when
appropriate. Older clients more apt to cling to ethnic food
habits, esp. During illness.

M.J. Bailey
Factors Influencing Dietary Patterns
3. Socioeconomic status. Food expenses fluctuate, spending depends
on $$ available. Whether someone is around to prepare the
food determines the amount of convenience foods used.
![Page 6: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/6.jpg)
M.J. Bailey
Factors Influencing Dietary Patterns
4. Personal preference Individual likes and dislikes provide the
strongest influence on diet Foods associated with pleasant memories
become favorite foods/ foods with unpleasant memories are avoided
Luxury foods = status Individual preferences used to plan
therapeutic diet
![Page 7: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/7.jpg)
M.J. Bailey
Factors Influencing Dietary Patterns
5. Psychological factors. Individual motivations to eat balanced meals
and individual perceptions about diet. Food has strong symbolic value.
Milk=helplessness. Meat=strength.
![Page 8: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/8.jpg)
M.J. Bailey
Factors Influencing Dietary Patterns
6. Alcohol and drugs Excess use contributes to nutritional
deficiencies Excess alcohol affects GI organs Drugs that appetite intake of essential
nutrients Drugs can deplete nutrient stores and
absorption in the intestines

M.J. Bailey
Factors Influencing Dietary Patterns
7. Misinformation and food fads Food myths can be the result of cultural
background, popular interest in natural foods, peer pressure, or desire to control diet choices
Fads may involve erroneous beliefs certain foods are esp. Healthy Yogurt better than milk Oysters sexual potency
Don’t be condescending when giving nutritional guidance

M.J. Bailey
Factors Influencing Dietary Patterns
Physical Problems– Teeth– Loss of neuromuscular control– Poor state of health
Psychological Problems– High point of day– Very degrading

M.J. Bailey
Types of Diets
Regular- (full/house/DAT)– Allows client selection
Clear Liquid- clear, bland ie: broth, gelatin, apple juice (little residue, easily absorbed)
Full Liquid –foods that liquify at room or body temperature. Easily digested & absorbed. – Milk+ creamed, strained soups– Pre & post-op patients– Those who can’t chew or tolerate solids
![Page 12: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/12.jpg)
M.J. Bailey
Types of Diets
Pureed- easily swallowed foods, no chewing
Mechanical or Dental Soft- foods don’t need chewing, avoid tough meats & fruits with tough skins
• Chewing problems
• Lack of teeth
• Sore gums
![Page 13: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/13.jpg)
M.J. Bailey
Types of Diets
Soft- low in fiber, easily digested easy to chew and simply cooked. No fatty, rich or fried foods (Low Fiber Diet)
High Fiber- Sufficient amt. of indigestible carbohydrates to :– relieve constipation– GI motility– stool weight
![Page 14: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/14.jpg)
M.J. Bailey
Types of Diets
Sodium Restricted– Low levels of sodium = NO SALT– CHF, Renal failure, cirrhosis, hypertension
Low Cholesterol– Cholesterol intake 300mg/day– Fat intake 30–35%– Eliminate/reduce fatty foods

M.J. Bailey
Adults usually eat independently but may need to be fed in the presence of physical or cognitive limitations.– Neurological– Neuromuscular– Orthopedic problems
Loss of control & independence can lead to psychological problems and depression.
![Page 17: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/17.jpg)
M.J. Bailey
Terms re Feeding
Dysphagia- difficulty swallowing – Most common cause of aspiration in adults
during feeding
Aspiration- the inhalation of foreign substance into the lungs – stroke
![Page 18: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/18.jpg)
M.J. Bailey
Suspect Dysphagia when client
Coughs/ gags during eatingExhibits multiple attempts @ swallowingc/o food getting stuck in throatPoor lip & tongue control
![Page 19: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/19.jpg)
M.J. Bailey
Feeding the patient with dysphagia
Safety – choking/ aspirationSymptoms of dysphagia
– Coughing, choking, drooling, spilling food ( pocketing)
– Provide food that stimulates swallowing– Don’t feed too quickly– Thickened foods easier to swallow
![Page 20: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/20.jpg)

M.J. Bailey
Intubation
Placemnt of a tube into the stomach or intestine through the mouth, nasopharynx, (Nasogastric/Levine), or through an artificial opening made in the abdominal wall of the stomach (gastrostomy) or small intestine (jejunostomy)
Nasogastric= short termGastrostomy= long term, surgically inserted
directly into the stomach(gastrostomy) or small intestine (jejunostomy)
![Page 24: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/24.jpg)
M.J. Bailey
Nasogastric tube
Through nose into stomach (infants through the mouth, nostrils too small)
Only with a physician’s orderEnsure correct tube placementPurpose
– Nutrition for clients with impaired swallowing, unconscious, or inability to ingest food
![Page 25: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/25.jpg)

M.J. Bailey
Do’s and don’ts re tube feeding
Do not hurry/force feeding– Abdominal distention & discomfort
Clean not sterile techniqueFormula @ room temp.
– Warm= bacterial growth– Cold= gastric cramping & discomfort, liquid is
not warmed by the mouth and esophagus
![Page 30: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/30.jpg)
M.J. Bailey
Do’s and don’ts re tube feeding
Formula can hang for 8hrs. ( check directions)Change tubing q24hrs. Or according to policyCheck tube position q8hrs. And ac feeds/medsClamp b/t feedings30-60 ml water before and after feedings, meds,
residual checks
![Page 31: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/31.jpg)
M.J. Bailey
Procedure for checking tube placement
X-ray- best and most accurateAir insertion and listen with stethoscopeAspirate gastric contents
– Determines tube placement and checks for digestion of previous feeding ( should be less than 50mls ) Note -any gastric contents should be returned to the stomach so the chemical balance is not disturbed.
– Check pH of aspirate with pH paper
![Page 32: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/32.jpg)
M.J. Bailey
Aspirate pH
Stomach is acidic 1-4Intestine is 7 or greaterPleural secretions 6Wait at least 1 hr after feedings to check
Feeding is not given if no bowel sounds are heard, abdomen is distended, too much residual, or tube dislodged
![Page 33: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/33.jpg)

M.J. Bailey
Fluid Intake and Output
3 main sources of fluids and electrolytes– Fluids ingested in liquids– Food that is eaten– H2O as a byproduct of oxidation of foods and
body substances
Total daily intake approximately
2100-2900mls
![Page 35: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/35.jpg)
M.J. Bailey
Fluid Loss
Fluids are lost– Skin– Lungs– Feces– Urine output = majority
Total daily loss = 2100 –2900mls
![Page 36: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/36.jpg)
M.J. Bailey
Regulation of Body Fluids
Fluid Intake primarily regulated by:– Thirst mechanism in hypothalamus
The thirst mechanism is affected by:– plasma osmolality– plasma volume– Dry mucus membranes– Other factors
![Page 37: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/37.jpg)
M.J. Bailey
Regulation of Body Fluids
Those at risk for dehydration include:– Infants– Elderly– Neurologically impaired– Psychologically impaired
Must be conscious and alert
![Page 38: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/38.jpg)

M.J. Bailey
Kidneys
Major regulators fluid balance– blood flow to kidneys urinary output– Amount of urine produced influenced by ADH
& aldosterone (stimulated by changes in blood volume)
– Urine output = 1.5L/day in adults or 60 mls/hr– Where Na goes H2O follows
![Page 40: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/40.jpg)
M.J. Bailey
Insensible Losses
Immeasurable– Evaporation through the skin
• Affected by humidity
– Lungs• Respiratory rate and depth
– Fever • Loss through skin & lungs
Infants lose more H2O from their skin than adults
![Page 41: M.J. Bailey Feeding Adult Patients. M.J. Bailey Nutrition Nutrition is an important treatment in any illness. Type 2: non-insulin –dependent diabetes.](https://reader035.fdocuments.net/reader035/viewer/2022070306/5519195455034642428b4a15/html5/thumbnails/41.jpg)

Sensible Losses
MeasurableFluid losses from
– Urination– Defecation– Wounds– Vomiting
Normally GI losses 100mls/day In cases of severe diarrhea , losses may exceed
5,000ml/day

Body Fluid Distribution
2 Basic Compartments– Intracellular- inside the cells, must be balanced with
extracellular
– Extracellular- outside the cells, further divided into• Interstitial fluid in the spaces b/t cells
• Intravascular or plasma- liquid portion of blood, watery, colorless fluid portion in which blood cells are suspended
Hint: Inter= between Intra= within/ inside

Fluids and Electrolyte Balance
Many solutes in the intracellular fluid compartment are the same as those located in the extracellular fluid space. However the proportion of the substances is different
ie: K > intracellularBody fluids & electrolytes shift from
compartment to compartment to maintain Homeostasis

M.J. Bailey
Fluids and Electrolyte Balance
Homeostasis maintained by:– Diffusion- solutes from areas to concentrations
across semipermeable membrane until =• Remember in diffusion solutes move
– Osmosis- passive movement of fluid from areas with more fluid and fewer solutes to areas with less fluid and more solutes across a membrane
• Remember in osmosis fluid moves
– Active transport• ATP( adenosine triphosphate) pushes against concentration
gradient• Solutes from concentration to concentration

Fluids and Electrolyte Balance
– Filtration-removing particles from a solution by allowing the liquid portion to pass through a membrane ( ex. Nephron of the kidney)
All body fluids contain similar substances although concentration may vary:– Electrolytes– Minerals– Cells

Fluids and Electrolyte Balance
Electrolytes– Substances which dissolve in solution
– Split into charged ions
– Conduct an electrical current
– + charged = cations( Na+, K+, Ca+)
– - charged = anions ( Cl-)
– Vital for body functioning• Neuromuscular
• Acid/base balance

Fluids and Electrolyte Balance
Body fluids are not stagnant – fluids and electrolytes shift from compartment to compartment to facilitate body processes such as acid/ base balance.
K+ most abundant intracellular cationNa+ most abundant in extraellular fluidWhere Na+ goes H2O follows Na+ retained K+ excreted

Variables Affecting Fluid and Electrolyte Balance
Age– Infants
• have more H2O• Greater risk for loss• Kidneys immature – not able to concentrate urine
– Elderly • Less body H2O• Decreased renal function- not able to concentrate urine
Body size– Fat does not contain H2O– body H2O in females b/c more fat deposits in breasts and
hips , obese have body H2O

Fluids and Electrolyte Balance
Environmental Temperature – – temperature sweating fluid loss = loss of Na+ and
Cl- ions.Life style
– Inadequate diet-• body breaks down glycogen and fat stores.• Next destroys protein stores• Decrease in serum protein (hypoalbuminemia)• Decrease osmotic pressure and fluid shifts from circulating blood
to interstitial spaces.
– Stress- fluid volume– Exercise- insensible H2O losses
