Reference--Easily swallowed and digested liquid food such as milk, bean milk, fruit juice, only for temporary use because of insufficient energy, 6-7 meals a day ml each time with total energy of kcal/ d and protein of 40~50g/ d.

13 Therapeutic Diets Therapeutic diets are based on the basic diets and used as treatment by adjusting total energy and certain nutrients.

14 High energy diet High protein diet Low protein diet Low salt diet Salt free and low sodium diet Low fat diet Low cholesterol diet Low residue or residue free diet High food fiber diet Therapeutic Diets

15 High energy diet Clients with diseases of high consumption of energy; such as tuberculosis, large area burns, liver diseases, and hyperthyroidism. Reference--In addition to basic diet, 2 more meals are added a day such as milk, bean milk, egg, cake, chocolate, with total energy of 3000kcal/d.

24 Test Diets(diagnostic diets ) Test diets are used to help diagnosis and insure accurate testing by adjusting the contents of diets in special time. Occult test diet Cholecystography test diet Creatinine test diet 131 I thyroid uptake test diet,etc.

25 Occult blood test diet The three-day test diet is used for preparation of occult blood test to assist the diagnosis of gastrointestinal bleeding. The client who is going to have the test is forbidden during this period any food that can lead to a false positive result, such as meat, poultry, medicine and food rich in iron, and green vegetables. The test sample will be taken on the forth day.

30 Affecting factors Physical factors psychological factors Sociocultural factors

31 Physical factors Age Physical activity Special life cycle status Age Physical activity Special life cycle status Physiological factors Pathological factors Disease and drug food allergies Disease and drug food allergies

32 Sociocultural factors Economic Situation Lifestyle Personal Preference Environment Knowledge About Nutrition

33 Diets status eating patterns Changes in appetite Influencing factors (impaired chewing or swallowing) Meals time Category and amount of Food intake

34 Physical status Physical Examination Anthropometric Measurements

35 Physical Examination Area of ExaminationSigns of Malnutrition General appearance and vitality Apathetic, look tired, easily fatigued Skin Dry, flaky or scaly; pale or pigmented; lack of subcutaneous fat NailsBrittle, pale, ridged or spoon-shaped HairDry, dull, sparse, loss of color, brittle Eyes Pale or red conjunctiva, dryness, soft cornea, dull cornea LipsSwollen, red cracks at side of mouth Tongue Swollen, beefy red or magenta colored; smooth appearance; decrease or increase in size Gums Spongy, swollen, inflamed; bleed easily MusclesUnderdeveloped, wasted, soft Clinical Signs of Malnutrition

36 Anthropometric Measurements Height and weight skin fold thickness arm circumference AC

37 Height and weight The standard of IBW IBW (kg) = [height(cm) – 100] × 0.9 IBW (kg) = height(cm) – 105 Calculating percent of weight loss or gain %weight loss IBW CBW / IBW×100% %weight gain CBW IBW/ IBW×100% normal :± 10 %

38 Body Mass Index(BMI) The normal range: 18.5~22.9 overweight :23~27.9 obesity: 28 WHO BMI = weight(kg) / height(m 2 )

39 The BMI values have two major drawbacks: they fail to indicate how much of the weight is fat; where that fat is located.

40 The fat lying deep within the bodys abdominal cavity may pose an especially high risk to health. deep within the central abdominal area of the body

41 skin fold thickness lean middling fat male 10mm 10 ~ 40 mm 40mm female 20mm 20 ~ 50 mm 50mm the triceps skinfold About half of the fat in the body lies directly beneath the skin.

43 Section 4 Diet nursing Diet administer Arrange the client's diet according to the diet orders. Meals care

44 Pre- Meals care During Meals care Post- Meals care

45 Pre- Meals care Diet education Preparation Stimulating the Appetite Environment client

46 Relieving illness symptoms that depress appetite prior to mealtime. Providing familiar food that the client likes. Avoiding unpleasant or uncomfortable treatments immediately before or after a meal. Providing a tidy, clean environment. Encouraging or providing oral hygiene for clients before mealtime Reducing psychological stress. Stimulating the Appetite

47 During Meals care Check the type of diet. Do not give an incorrect diet for clients. Assist clients who cannot help themselves to remove the food. For a blind client, identify the placement of food as you would describe the time on a clock. soup (12 ) vegetables(9) vegetables (3 ) rice (6 )

48 Post- Meals care replace the food covers and give the client care. note how much and what the client has eaten and the amount of fluid taken. If the client's intake and output of fluid is being recorded, nurse should record. Pay attention to the fasting client especially on shift.

49 Section 5 Special diet nursing Enteral Nutrition (EN) * Tube feeding * Elemental diets Parenteral Nutrition (PN)

50 tube feeding nasogastric gavage – is a medical approach to maintain clients nutrition and ensure treatment by inserting a tube to gastrointestinal duct via nasal cavity, through which fluid food, water, and medicine are infused.

51 Elemental diets Elemental diet is a purified food whose chemical composition is definite and it contains all the required nutrients of human body. severe burn and trauma digestive tract fistula the nutritional support of pre-operation and post-operation non-infectious diarrhea malabsorption and malnutrition, etc.

52 Purpose Elemental diet could achieve the Therapeutic and adjunctive therapy effect for the severely ill patients.

53 intermittent infusion continuous infusion fractional infusion Administration

54 Complications Mechanical complications Infectious complications Gastrointestinal tract complications Metabolic complications

55 Notes to nursing It should be initially offered in a small amount and can be increased gradually at a low and slow pace when patients are tolerated well then stabilize the prescription, dosage and transfusion rate. Follow sterile procedure and prevent contamination. Prepared feedings should be stored in refrigerator below 4°C and should be used up in less than 24h. The infusion temperature is 41°C 42°C, and take it orally in 37°C. Irrigate the tube with warm water before and after infusion, which prevent tube from obstruction.

56 Continue Clients need some necessary lab tests such as blood glucose, urine glucose, blood urea nitrogen, electrolyte. Observe clients' urine and stool, record client's weight, and monitor 24h intake and output. Observe the client's response during feeding. When clients have some symptoms such as nausea, vomit, abdominal distention, and diarrhea, nurses should find the reason, adjust infusion rate and temperature, and stop infusion for severe clients. The feedings is stopped gradually to prevent hypoglycemia.

58 Parenteral Nutrition (PN) PN also referred to as total parenteral nutrition (TPN). PN is provided when the gastrointestinal tract is nonfunctional. PN is administered intravenously through a central venous catheter into the superior vena cava. Clients who accept PN therapy include those with severe malnutrition, severe burns, bowel disease disorder, acute renal failure, hepatic failure, cancer or major surgeries where nothing may be taken by mouth for more than 5 days.

59 Nursing care for the client's receiving PN is based on three major nursing goals: preventing infection; maintaining the PN system; preventing complications such as metabolic, electrolyte or fluid balance.

60 Observation and nursing during infusion Monitoring Prevention of complications and nursing of client with complications

61 Complications related to catheterization Infection Metabolic complications
