II. A. Role of Nutrients in the Maintenance of Normal Growth 1. Food and its function Food includes articles used as drink or food and the articles used for the component of such. Milk, fish, egg, fruit and vegetable are tangible food. Nutrients are not seen by the naked eye. Milk is a food comprise of water, carbohydrate, fat, protein, mineral and vitamins. Water is a beverage which is considered food as well as nutrient. Kalamansi juice is food that contains water, carbohydrate and mineral and vitamins. Denotes that food can be simple or complex in its chemistry and contains nutritional and or non nutritional and or nor nutritional components (Food coloring, spices and preservatives) Functions of food: Nourishes the body by building and repairing tissues. Supplying heat and energy Regulating bodily processes

Sustains life second to oxygen 2. Digestion and absorption Review Anatomy of Digestive Tract a. Digestion Digestion is accomplished mechanically by chewing and swallowing in the mouth. The storage, mixing and controlled emptying occurs in the stomach and intestines. Digestion chemically happens by the actions of enzymes resulting the eventual splitting up of food stuff into simple components. Enzymes are protein in nature, substances that initiated and accelerate chemical reactions without undergoing change. Digestion in the mouth With the entrance of food in the mouth, digestion started by means of mastication. When masticated food mass (called bolus) is swallowed, it passes downward to the esophagus by means of muscular contraction. Digestion in the stomach Stomach receives the food and acts a reservoir for a short time. Food reduced to semi fluid (called chime) The acidity of the stomach (caused by HCL) stops the digestive action ptyalin in the food mass. Thick slimy mucus called mucin is secreted from the stomach wall to protect the cells from being digested by the enzymes. All foods are liquefied and mixed with the HCL acid. The acid medium is also responsible for the reduced activity of harmful bacterial that may have been taken in with the food. It also provides favorable medium for absorption of Calcium and other minerals. The food leaves the stomach in the form of chime.

12

Stomach is normally emptied in 1-4 hours with carbohydrate leaving the stomach rapidly followed by fats. Digestion in the Large Intestine The large intestine does not take part in the digestion of food. Any bulky and unused parts of the diet are passed on to it. In the colon, water is reabsorbed causing the formation of a fairly solid mass. When the rectum is reached, the mass is evacuated in the form of feces. This consists of undigested food fibers, bacteria, cell cast off from the intestines and some mucus and some salts. b. Absorption When the products of digestion pass through the lining of digestive tract into the blood stream and lymph, it is termed as absorption. The absorption of digested food takes place largely in the small intestine through villi. The villi are fingerlike projections lined in the intestinal wall which increase the surface area for absorption. The absorption in the small intestine may be accomplished by a number of processes depending on the nature of the nutrient and the prevailing pressure gradient. Passive diffusion and osmosis – small molecules passed through the capillary membranes and diffuse easily into capillaries of the villi depending on the pressure. Facilitative absorption or carrier-mediated diffusion – molecules which are large enough to traverse the membrane pores are helped by the specialized transport systems which carried the large molecule through the barrier. Energy dependent active transport – the nutrient molecules must pass through the intestinal membrane to supply the materials needed by the body even against a pressure gradient and this mechanism requires extra work and energy.

13

Engulfing (pinocytosis) – when very large molecules are involved, the intestinal villi act like amoeba or leukocytes by ingesting foreign particles into the interior of the cell. This method is used for fat metabolism. B. Various Nutrients of Food Water Next to oxygen, water is essential to stay alive. If about 20% of body water is lost, death results. Water accounts for about 60-65% of body weight for normal adult. Functions of Water a. Universal solvent, it carries simple sugar, amino acid, lipoproteins, vitamins and minerals for transportation to the different tissues for proper functioning and nourishment. b. Used to excrete waste products from lungs, skin and kidneys. c. Serves as transport medium for many biological reactions especially in digestion and absorption and circulation. Participates in maintaining electrolyte balance. d. Vital component of every cell, organ and tissue in the body. e. Water acts as lubricant of the joints and the viscera in the abdominal cavity thus can protect a sensitive tissue. Moisten the eyes, nose and mouth. Hydrates skin. f. Regulator of the body temperature through its ability to conduct heat. g. Acts as a shock absorber inside the spinal cord and amniotic sac surrounding the fetus. Protein Contains several millions of protein molecules, building blocks of protein are amino acids. Protein is needed for building and repairing cells and specialized role in metabolism.

14

Classification of Amino Acid a. Essential – cannot be synthesized by the body from materials readily available at a speed to keep up normal growth rate. Referred to as dietary essentials. b. Semi-essential (semi indispensable) amino acid reduces the need for particular essential amino acid (EAA). Amino acid that can maintain life processes for an adult but not enough for normal growth in children. c. Non-essential amino acid (NEAA) – “dispensable amino acid” – not a dietary essential. It can be essential by the body as long as the materials for synthesis are adequate. Carbohydrates Originally called “Saccharides” sugar Organic compound abundant in plants and wide spread in nature. Classification: a. Monosaccharides – simplest form of sugar • Glucose – dextrose or grape sugar - Most important sugar in human metabolism. Known as “Physiologic sugar.” It is also the circulating carbohydrate. • Fructose – sweetest of all sugar and found preformed in honey, ripe fruits and some vegetables. • Galactose – not found in nature but is hydrolyzed from fructose or “milk sugar.” Glucose is converted to galactose to form sugar or lactose in breast milk. • Sugar alcohols – have sweetening power as glucose. a. Mannitol – poorly absorbed in the intestines and used a food ingredient and as drying agent. b. Sorbitol – absorbed slowly than other monosaccharide and it has been used to delay the onset of hunger.

15



Pentoses – found in meat and sea foods in bound form. Important component of nucleic acid and some co-enzymes.

b. Dissacharides – “oligosaccharides” two sugar unit base • Sucrose – “ cane sugar to beet sugar” since it is commercially prepared from sugar cane and sugar beets. Also abundant in molasses, maple syrup, sorghum. Also known as table sugar. • Maltose – “malt sugar” because it is derived from the digestion of starch with the aid of the enzyme, diastase found in sprouting grains. It is usually combined with dextrin for infant milk formula. • Lactose – “milk sugar” found in milk and milk products. Least sweet among sugars only 1/16 as sweet as sucrose or table sugar. c. Polysaccharides – not water soluble sugar • Starch- most abundant and cheap form of carbohydrate. Storage formation in plants, grains. • Dextrin – intermediate product digestion or formed from partial hydrolysis of starch. The action of dry heat o starch (as in toasting bread or browning of cake crust in the oven) produce dextrin. • Glycogen - “animal starch” because its storage form of carbohydrate in the body, chiefly in the liver and muscles. a. Muscle glycogen – used directly to supply energy for the surrounding tissues as during exercise and work. b. Liver glycogen – changed into glucose and circulate as such by the blood to other parts of the body.

16

4.

Fats Called lipids are actually family of compounds that include both fats and oils. The body’s fat mass has virtually unlimited storage capacity and fat supplies 2/3 of body’s ongoing energy need. During a prolonged period of food deprivation fat stores may make even greater contribution to energy needs. - Helps maintain the health of the skin and hair. - Protects organs from temperature extremes and mechanical shock. - Provides a continuous fuel supply, helping to keep the body’s lean tissue form being depleted. - Carrier of fat soluble vitamins A, D, E, K.

5.

Minerals Found in unrefined food mostly combination with each other and other organic constituents. Traces can be found in water. In the body minerals compromise about 4-6% of total body weight. The rest of the body weight consists of water 63%, protein 18%, fat 13%, carbohydrate 1%. Functions • Structural – refers to the presence of the mineral in significant amounts to be part of the cells or body fluids of as an important component of a molecule. - Calcium, phosphorus and magnesium in the bones and teeth, iron in rbc, iodine in thyroxine, chlorine in gastric secretion. • Regulatory – these includes physiological processes for normal functioning of tissues. - Maintenance of acid base balance a. Acid forming- chlorine, sulfur and phosphorus b. Base – calcium, sodium, potassium and magnesium.

17


• •

Catalysts for metabolic reactions – potassium, calcium, magnesium and phosphorus hasten the anabolism of glucose to form glycogen. Regulator of muscle contractility-minerals maintain normal contraction and relaxation of muscles including magnesium, potassium, sodium, calcium Transmitter of nerve impulses – during stimulation of a nerve fiber, Na and K exchange with each other across the cell membrane to facilitate the transmission of a nerve impulse.

Classification • Macrominerals – calcium (Ca), Phosphorus (P), Potassium (K), Sulfur (S), Sodium (Na), Chlorine (CI), Magnesium (Mg). • Microminerals – Iron (Fe), zinc (Zn), selenium (Se), Manganese (Mn), Copper (Cu), Iodine (I), Flourine (F) 6. Vitamins - Organic compounds that are required in small amounts for normal growth, reproduction and maintenance of health. - Vitamins are co- enzymes. It helps to initiate a wide variety of body responses including energy production use of minerals and growth of healthy tissue. Vitamins do not provide energy. Characteristis a. Organic compounds – all vitamins have carbon, hydrogen and oxygen in their chemistry component. b. Potent minute quantities – very small concentrations of vitamins needed to maintain life and normal growth. Measurements range from micrograms. (mcg or ug) c. Dietary essentials – vitamins are ingested from diet.

18

Fat Soluble Vitamins • Vitamin A (Retinol) - Maintains the integrity of epithelial tissues, especially mucus linings. It is needed for normal night vision. - For normal bone and skeletal growth. Excessive use causes complete disintegration of bone matrix. - For nervous and reproductive system need vit. A for stability of cell membrane. Excessive amounts of retinol make the membrane abnormally susceptible to rupture as observe in hypervitaminosis A. Sources - Animal sources, liver, eggyolk, milk, cream, butter, cheese. Fishes, “dilis”, clams, tahong and shell fish. Fish liver oil are richest natural source. • Vitamin D - Promote normal bone and teeth development because it facilitates absorption of calcium and phosphorus. - Lack of vit D results in reduced intestinal absorption of Calcium and phosphorus Sources - fortified margarine, butter, milk and cheese, liver, other organ meat, sardines, salmon and egg yolk. Vitamin E - Prevention of hemolysis of rbc( separation of Hgb from rbc) - Anti oxidant in both animal and plant tissues. Sources – wheat, corn, cottonseed, soybean, mayonnaise, salad dressing, margarine, nuts and legumes. Vitamin K - Maintenance of prothrombin level in blood plasma. Sources – liver, dark green leafy vegetables, wheat, bran, vegetable oils, soybean oil and wheat germ, tomatoes, legumes, egg yolk

III. ASSESSING NUTRITIONAL NEEDS A. Physiologic Importance of Food Nutrition provides information about how much of each nutrient is needed and under what circumstances, and about the types and quantities of food that provide the necessary nutrients. Foods that should not be eaten and the reasons for this are also identified. The functions of nutrients; how they interact; what happens when there is a lack, excess or an imbalance of nutrients; and the processes by which the body digest, absorbs, uses and excretes the end-products of food eaten are included in the science of nutrition. Role of Nutrition on Growth and Development a. Food Maintains Life - Certain nutrients in food are required by the cells for growth, repair, rebuilding, and regulation of function. - Retarded growth and delayed sexual developments results from deficiencies of certain nutrients. - The combination of severe malnutrition and infection may result in permanent growth retardation and increased susceptibility to disease. b. Skeletal Growth and sexual Development - The growth pattern of a child is useful means for judging nutritional well being. - When a child is poorly nourished, the growth rate diminishes partly because of a delay in bone development. - the quality of the bone (amount of calcium and phosphorus it contains) and its capability for growth are influenced by nutrition. - Sexual maturity appears later in populations that are malnourished than in developed countries and occurs at an earlier age in each succeeding generation.

22

c. Mental Development • 5 months before birth and 10 months after birth - Period wherein most rapid growth of the brain occur. • At the end of the first year of life - The brain is the first organ to attain full development. - Poorly nourished babies have fewer and smaller brain cells. - Other factors that affect mental development > Heredity > Presence of disease > Emotional state > Home development - Severe deficiencies of specific nutrients can cause adverse structural changes and impaired functioning of the central nervous system. - Symptoms such as anxiety; irritability; depression, mental, confusion, and physical and mental apathy (loss of interest) are associated with certain deficiency diseases and may influence learning ability. E.g. Iron deficiency anemia among school children may interfere with motivation and the ability to concentrate for extended periods of time. - Iron deficiency may cause a reduction in iron-containing enzymes in brain tissue which is turn cause alterations in brain function. - Poorly nourished persons who tire easily, have little energy, and are unable to concentrate will have difficulty achieving their intellectual potential.

23

1. Required Nutrition Across the Lifespan a. Pregnancy and Lactation • The nutritional status exerts its greatest influence during pre-natal life and infancy (weight increase 2x at 6 months; 3x at 12 months; and 4x at 18 months.) • Within 2-3 months all the major body systems are formed (heart, lungs, brain 1st trim) • Task of the body during pregnancy: changes in the respiratory and circulatory systems (increase blood volume leads to the accumulation of fluid and increase in plasma = dilutional anemia dec. RBC); hormonal secretions (progesterone maintains pregnancy and prepares breast for lactation) • Prepare for lactation, provide for growth and development • A gain of about 24 lbs, or 10.9 kgs (22-28 lbs or 10-12.7 kgs.) for an average normal woman • Requirements for all nutrients increases. • The caloric increases about 300kcal/day during pregnancy. Meat, fish, poultry, milk, eggs and cheese are high biologic value and should be used liberally. • Each additional cup of milk (ANMUM 2x) add 8g of CHON to the diet, milk also provides Ca and P which are needed for the development of the fetal bony structure and teeths as well as for mother. Fortified milk also supplies 400IU of vit.D/ quart. • Lean meat, prune juice, dried peas and beans, green leafy vegetables and whole grain cereals are good sources of Fe. Including Vit.C rich foods with meals increases the absorption o nonheme Fe. • The recommendation for folacin increases substantially for brain development of the fetus.

24

• •

Moderate use of salt is recommended since the tissues of both mother and fetus requires salt. Iodized salt should be used because of the increased need of iodine in pregnancy. The need of water is also increased; the diet should include 6-8 cups of fluid; which can be obtained from a variety of beverages. Several glasses of water should be drunk each day.

NUTRITION IN LACTATION • (+) 15g in 6 months and (+) 12g in months for the CHON requirement • Vitamins and minerals – increases Vit. B6, Se, I, Vit. D • Increase water and fluid intake – 87% of BM is water. • Breast milk – unique in concentration of macro and minerals, enzymes, hormones, induces, modulators of immune systems and anti-inflammatory • Colostrums – first breast milk FACTORS AFFECTING MILK COMPOSITION • Stage of lactation- preterm milk – high in nitrogen • Colostrum – 2 days high in CHON, low in fats and CHO, 3-6 – low CHON, high in CHO and fats • Maternal diet – all women – enough with high quality BM; CHO; Ca; P, Mg and CHON concentration is not affected - Concentrated FA, Vit. B6. Vit. D, I, Se – depends on maternal reserves BREASTFEEDING • Best for babies – all essential nutrients are present • Natural – no flavoring and preservatives • Presence of anti-infections

25

Sterile, proper temperature Better for jaw 7 teeth development Maternal and child bonding

MOTHER • Mobilize fats • Early stage (immediate post-partum); promotes uterine contraction (oxytocin and prolactin secretion)- prevents hemorrhage and thromboembolism • Readily available • Childbirth and BF is a protection against CA – overuse (Ca of the cervix); underused (Ca of the ovary) • Contraception: LACTATIONAL AMMENORHEAL MENSTRUATION – 0-6 months GUIDELINES IN FORMULA FEEDING • Avoid putting the child to be with bottle –destroy teeth, otitis media • Hold baby as if mother is breast feeding – bonding • Do the right mixing of formula and water as indicated in the commercial formula WEANING – breastfeeding is gradually reduced with infant formula or foods appropriate to infants 4-6 months. INTRODUCTION OF SOLID FOODS • Infant cereal (4th) – veg and fruits (5th) – strained meats/ egg yolk (6th-7th) • Introduction to table foods – 9th months coarsely textured foods.

26

GUIDELINES IN INTRODUCING SOLID AND TABLE FOODS 1. Introduce new foods one at a time at least 4-5 days of interval for child to adjust to new food and to determine food allergies. 2. Introduce plain/ simple foods. 3. Increase fluid intake once solid foods are introduced. b. Infancy ENERGY REQUIREMENT: 12 kcal / kg – 0-11 months (3x higher than adult req’t = 40 kcal in adult) – inc growth and development; 100 kcal/kg in year old BREASTMILK AND FORMULA MILK; 67 kcal/ 100 ml FLUID REQUIRMENT: 150 ml/ kg in 24 hours - If extra water is excreted – increase fluid intake (fever, vomiting, diarrhea) - if (+) solid foods – increase fluid intake CHON REQUIREMENT: 2.2 g/ kg = 0-6 months; 1 8g/kg in 6 months and above, e.g. baby is 3 kg 120 kcal/ 1 kg = x /3kg = 360>360 kcal/x ml x 67 kcal/100 ml = 537 ml/day FAT REQUIREMENT: not specific = 48% BM and 46% FM CHO REQUIREMENT: - BREASTFEEDING: lactose = 2-3 hours or 8-10 feeding

27

PHYSIOLOGY OF BF: sucking reflex > release of PROLACTIN > signals mammary gland to be filled with milk> Release of OXYTOCIN> contraction of breast and release of milk a.k.a LET DOWN REFLEX 0-6 months supplement bottle for 1st 4 months is discouraged BM is already enough. CONTENTS OF BREAST MILK 1. Lactose – well tolerated by the baby = efficiently digested and used by the GIT of the baby. 2. Essential fatty acids – linole, llinoleic, arachidonic and DNA (decoxahexaenoic acid) helps the utilization of fats especially cholesterol; DHA is abundant in the brain and retina of the eye, breastfed children are smarter with shaper cognitive abilities and sharper vision. 3. 4. 5. 6. 7. CHON – alpha lactalbummi – concentration is low – efficiency used by the baby – if high concentration will increase kidneys workload. VITAMINS – all vitamins are present except for Vit. D so expose the baby to enough sunlight proper Vit. D usage. MINERALS CALCIUM – for bone and teeth formation. LOW IRON and ZINC – HIGH BIOAVAILABILITY = maximum utilization/ absorption of minerals.

Set good examples of eating right food – avoid showing them your dislike on food. 2. Associate food with love and understanding – provide accurate information 3. Not all children have the same responses toward food – think of what / how much they’ll like it. 4. A child is keen on taste, flavor, texture and temperature – prepare nice, attractive, colorful food. 5. Satisfy his curiosity by giving him an opportunity to handle ingredients and acquainting him with pictures and names of food – interest. 6. What a child thinks about himself and his world shows his sentiments on food. FEEDING PROBLEMS OF PRE-SCHOOLERS Eating too little – same food served everyday, emotional problem; NI; serve variety of food and prevent argumentation in the table. Eating too much – heredity (vocarious); clean plate principle> inc. weight/ obese, indigestion. Dawdling – lingering with food > to get attention from authoritative figures (parents) or indicates loss of appetite due to infections present > let child be checked. Gagging – feels like vomiting especially with coarse foods> neglect to introduce food at the right time. Allergy – observe for 4-5 days to give way for allergies to come out. e. School Age Slow growth rate, height is increased by 2-2.5 per year, weight by 4.5 lbs between 6-8 y/o

30

Soluble fiber fruits, vegetables and whole grain cereals will promote normal elimination. 3. A glass of milk, or flavored with malt, cocoa before going to bed can induce sleep (TRYPTOPHAN). 4. Those who cannot tolerate milk, excellent local food sources can provide the major minerals. (ex. Dilis, tinapa, small shrimps, balut, malungay) 5. Avoid too much fatty foods 6. Coffee and tea before going to bed may prevent a good sleep 7. Small frequent feeding 2. Malnutrition - Condition of the body resulting from lack or excess of one or more important nutrients. - Also condition in which an individual cannot perform well at such things as physical work, physical growth, pregnancy, lactation and resisting or recovering from illness. FORMS OF MALNUTRITION a. Protein-Energy Malnutrition (PEM) - A condition resulting from the lack of intake of energy or protein or both, characterized by marked loss of weight and failure to grow.

33

- Effects/Clinical Manifestations * Stunted physical and mental development * High risk to infection * In extreme cases, death * Lower academic performances * Lower levels of productivity b. Iron Deficiency Anemia (IDA) - A condition where there is not enough hemoglobin in the red blood cells due to lack of iron. RBC – also known as erythrocytes - Hemoglobin – reddish protein containing iron. Characterized by feeding of fatigue, anxiety, and sleepiness and reduced work capacity. - IDA increases the risk of infections and even dying especially among pregnant and lactating women as well as infants. c. Iodine Deficiency Disorder (IDD) - A condition resulting from iodine deficiency or the failure of the thyroid gland to obtain a supply of iodine sufficient to maintain normal structure and function. - Characterized by the swelling of the neck or goiter (BOSYO). However, even before goiter becomes visible, iodine levels in the body are reduced. - The deficiency may be due to low intake of foods rich in iodine (e.g. sea foods and seaweeds) and may be prevented through the regular use of iodized salt. SERIOUS CONSEQUENCES OF IDD

34

- Increased miscarriages - Stillbirths - Spontaneous abortions - Irreversible mental retardation - Cretinism - Physical abnormalities such a deaf-mutism, squint (Pagkaduling) - Increased mortality among children - Iodine deficient adults have lower levels of productivity. d. Vitamin A Deficiency (VAD) - Results because of low intake of animal foods, and green leafy and yellow vegetables and yellow fruits, which are rich sources of vitamin A. - May also be due to poor absorption and utilization due to low intake of fats in the diet. - It may result from severe infections. - Common consequence is NIGHT BLINDNESS (matang manok). Frequent and severe infections may occur which may result to death in extreme cases. - The deficiency also results to poor growth. Undernourished persons do not tolerate illness well. - Shows delayed wound healing. - Susceptible to infection and complications of illness - Unable to withstand and handling medical treatments. 3. Measuring Nutritional Status

35

- Well nourished person have general energy appearance of vitality and well being. - They are alert, have sufficient energy to perform physical activities, and recover rapidly from periods of stress. However, it doe not mean that it is only due to lack of nutrition. It could also be caused by non-traditional factors such as lack of rest or emotional stress. a. Medical History - Before the physician examines the client, a medical history is taken. - A carefully taken medical history provides much information that is useful in the nutritional assessment. E.g. History of hypertension, alcoholism, surgery, or physical disability. - During physical examination (examine skin, mouth, and eyes, etc.) the examiner looks for physical signs and symptoms associated with malnutrition, a hormone imbalance, or chemotherapy. - Vital signs such as pulse rate, respiration, temperature and blood pressure provided additional physical data. Anthropometric measurements - Body measurements such as height, weight, skin fold thickness, and mid arm circumference that reflect growth and development or an increase in body fat and muscle tissue. Height and Weight - height and weight tables are used to evaluate an individuals weight as it corresponds to his or her weight. Head Circumference - An important measurement when assessing infants and young children. (May reflect the effect of nutrition on brain growth).

36

Skinfold Thickness - A measurement of a double layer skin and subcutaneous fat using a skinfold caliper. - The amount of fat in the body is an important indicator of nutritional status. Laboratory Data Blood, urine, and stool tests reveal much about what foods have been eaten, the quantity of certain nutrients in the body stores, and how the nutrients are being used. Laboratory Serum Albumin levels Measurement of the amount of this main protein in the blood is used to determine protein status. Serum Transferring Levels The amount of this iron-carrying protein in the blood increases above normal if iron stores is low; it decreases when the body is lacking protein. Total Lymphocyte Count The count of white blood cells, which defend the body against infection, is a measure of the body’s immune function, and may or may not reflect nutritional status. When protein intake is inadequate, the lymphocyte count decreases. Radiographic Studies Radiographic of the bones, wrist of bones of children are particularly useful. These bones appear earlier and develop earlier in well-nourished children.

37

Nutritional such as rickets and scarring can be detected by radiograph. Existed for a long time. Diet Hx and Food Intake Record Diet recall, food diary, food frequency record, frequency of consumption of food.

SURGERY NUTRITION • Before surgery, the patient must have an optimal nutritional status. a) To enable them to withstand the stress of surgery. b) To speed up the recovery time. c) To shorten period of hospitalization.

Nursing Considerations: a. b. c. d. e. f. g. h. Patients with mouth sores should be served foods at cooler temperature. Patients who have difficulty chewing and swallowing due to a reduced flow of saliva can increase salivary flow by sucking of sour candy or chewing gum. Encourage the patient to eat a variety of foods, all foods and seasonings are permitted. Provide plenty of fluids with meals to ease chewing and swallowing of foods. Sucking fluids through a straw may be easier than drinking them from a cup or glass. Liquid, chopped, pureed, or regular foods with a soft consistency are best tolerated. Avoid foods that contain nuts or seeds because these can become easily trapped in the mouth and cause discomfort. Avoid raw fruits and vegetables, fried foods, and whole grains.

D. BLAND DIET 1. 2. Indications: Used for gastritis, ulcers, reflux esophagitis, congestive heart failure (CHF) and myocardial infarction (MI). Nursing Considerations

51

a. b. c. d.

Bland foods are less likely to form gas than regular diets. Eliminate foods that stimulate gastric acid secretions. Eliminate foods that are irritating to the gastric mucosa. Foods to be avoided include alcohol, caffeine-containing beverages such as cola, cocoa, coffee, tea, fried foods, pepper and spicy foods.

E. LOW RESIDUE / LOW FIBER DIET 1. Indications: a. b. 2. Supplies foods that are least likely to form an obstruction when the intestinal tract is narrowed by inflammation or scarring, or when GI motility is slowed. Used for inflammatory bowel disease, ileostomy, colostomy, partial obstructions of the intestinal tract, enteritis, or diarrhea.

Indications: Severe stress, burns, cancer, human immunodeficiency virus (HIV) and AIDS, chronic obstructive pulmonary disease (COPD), respiratory failure. 2. Nursing Considerations: a. b. c. d. e. High-calorie diets are also high-protein diets because the purpose of the diet is to build or maintain lean body mass. Add fats to foods whenever possible. Add nuts and dried fruits such as raisins to desserts or cereals. Add sugar to food and encourage high calorie desserts. Encourage snacks between meals, such as milkshakes and instant breakfasts.

I. SODIUM-RESTRICTION DIET 1. Indications: Hypertension, CHF, kidney diseases, cardiac diseases, and cirrhosis.

54

2.

Nursing Considerations: a. b. c. The amount of sodium allowed varies from 250 mg to about 4 g daily. A No-Added-Salt Diet includes no salt at the table and lightly salting foods during cooking. Foods allowed on a sodium-restricted diet include dried or instant cereals, puffed wheat, puffed rice, and shredded wheat.

J. PROTEIN-RESTRICTED DIET 1. Indications: Acute renal failure, chronic renal disease, cirrhosis and hepatic coma. 2. Nursing Considerations: a. b. c. Provide enough protein to maintain nutritional status but not enough to allow the build-up of waste products from protein metabolism (40 – 60 g of protein daily). The lower the amount of protein allowed, the more important it becomes that all protein included in the diet be of high quality. An adequate total energy intake is critical for patients on protein-restricted diets because without adequate energy, protein will be used for energy rather than in protein synthesis.

55

d. e. f. g. h.

To boost energy intake, patients may use fats and concentrated sweets from margarine, creamed butter, hard candy, jelly and sugar whenever possible. Specially low-protein products such as pastas, breads, cookies, wafers, and gelatin made with wheat starch can improve energy intake and add variety to the diet. Carbohydrates in powdered or liquid forms can also provide additional energy. Vegetables and fruits contain some protein and for very-low-protein diets, these foods must be calculated into the diet. Foods are limited from the milk, meat, break and starch exchanges.

K. HIGH-PROTEIN DIET 1. Indications: Tissue building, burns, liver disease and maternity patient. 2. Nursing Considerations:

56

a. b. c.

High-protein diets correct protein loss or assist with tissue repair. Increase foods such as meat, fish, fowl, and dairy products. Client may need protein supplements.

L. LOW CALCIUM DIET 1. Indications: To prevent renal calculi. 2. Nursing Considerations: a. b. Decrease the total intake of calcium to prevent further stone formation. Avoid whole grains, milk, dairy products and green leafy vegetables.

M. LOW-PURINE DIET 1. Indications: Used to treat gout. 2. Nursing Considerations: a. Purine is a precursor for uric acid that forms stone and crystals.

57

b.

Include organ meats, meat, egg yolks, whole wheat products, leafy vegetables, dried fruit, and legumes.

O. DIET FOR DIVERTICULAR DISEASE 1. 2. 3. Foods with seeds need to be avoided as they get trapped in the diverticula and cause irritation. Foods to avoid include whole grain breads and cereals, fruits, vegetables, dried beans, peas, and nuts. Gas-forming foods should be avoided in patients with irritable bowel syndrome.

P. FLUID RESTRICTIONS DIET 1. Indications: Acute renal failure oliguric phase, chronic renal disease, cirrhosis, CHF, hepatic coma, MI. 2. Nursing Considerations: a. b. usually this diet restricts those foods that are composed largely of water. Restrict carbonated beverages, coffee, juices, milk, tea, water, frozen yogurt, gelatin, ice cream, ice milk, popsicles, sherbet, soup, cream, and liquid medications.

Q. CARBOHYDRATE-CONTROLLED DIET

58

1.

Indications: a. b. Help maintain normal glucose levels in-patients with disorders that cause blood glucose levels to rise or fall abnormally, such as diabetes or hypoglycemia. Used for diabetes mellitus, hypoglycemia, lactose intolerance, galactosemia, dumping syndrome, obesity and overweight.

2.

Nursing Considerations: a. b. Adjust energy intake from foods to provide specific amounts and types of carbohydrates. The exchange list system most frequently used to plan carbohydrate-controlled diets.

ENTERNAL NUTRITION A. Description

59

1. 2. 3.

Tube feedings that consists of blenderized food or prepared products that provide carbohydrates, fat, protein and water. Administered through nasogastric or gastrostomy tube. Administered continuously or intermittently.

B. Indications: 1. 2. When the gastrointestinal (GI) tract is functional but oral intake is not feasible. Used for patients with swallowing problems, cancer, burns, major trauma, liver failure, or severe malnutrition.

C. Administering Enternal Feedings 1. 2. 3. 4. 5. 6. 7. 8. 9. Keep the head of the bed elevated to prevent aspiration. Warm feeding to room temperature to prevent diarrhea and cramps. Check placement of tube every 4 hours by aspirating gastric contents and measuring the pH (should be 4 or less). Aspirate all stomach contents (residual), measure the amount, and return contents to the stomach to prevent electrolytes imbalance. Usually, if residual is less than 100 to 150 mL, feeding is administered, if greater than 150 mL, hold the feeding. Check for bowel sounds, hold the feeding if bowel sounds are absent and report the findings. Flush turbing with water following feeding to maintain fluid balance and patency of tube. Use a feeding pump for continuous feedings. Do not allow feeding to hang longer than 8 hours and change feeding bag every 24 hours to avoid contamination.

60

D. Prevention of Complications 1. Diarrhea a. b. 2. Use fiber-containing feedings. Administer feeding slowly and at room temperature.

Aspiration a. b. c. d. Verify tube placement. Do not administer feeding if residual is greater than 150 mL. Keep the head of the bed elevated. Is aspiration occurs, suction as needed, monitor temperature for aspiration pneumonia, monitor for dyspnea, monitor RR and prepare the patient for a chest radiograph.

3.

Clogged Tube a. b. Flush the tube with 20 to 50 mL of water before and after feeding administration. Flush with water every 4 hours for continuous feeding.

4.

Vomiting a. b. Administer feeding slowly, and for bolus feedings, make feeding last for 30 minutes. Measure abdominal girth.

61

c. d. e. f. g. h.

Do not allow feeding to run dry. Do not allow air to enter the tubing. Administer feeding at room temperature. Elevate the head of the bed. Administer antiemetics as prescribed. If patient vomits, place in side-lying position.

TOTAL PARENTERAL NUTRITION (TPN) A. Description 1. 2. 3. Supplies necessary nutrients via veins. Supplies carbohydrates in the form of dextrose, fats in a special emulsified form, proteins in the form of amino acids, vitamins and minerals. Prevents subcutaneous fat and muscle protein from being catabolized by the body for energy.

B. Indications 1. 2. 3. 4. When the GI tract is severely dysfunctional or nonfunctional. Patients who can take some oral nutrition, but not enough to meet the body’s needs. Patients with multiple GI surgeries, GI trauma, severe intolerance to enteral feedings, intestinal obstructions, or when the bowel needs to rest for healing. Patients with AIDS, cancer, or malnutrition.

62

C. Intravenous Sites 1. Peripheral Parental Nutrition (PPN) a. b. 2. Administered through a peripheral vein. Used for short periods (5-7 days) and when the patient needs only small concentrations of carbohydrates, fats and proteins.

D. Complications Infection Hyperglycemia Fluid overload Air embolism E. Precautions

63

1. 2. 3. 4. 5. 6. 7.

Assist with insertions of catheter, position the patient in trendelenburg position with a towel under the scapula. Ask the patient to perform the valsalva maneuver insertion to prevent air emboli. When the central line is inserted, placement is confirmed by chest x-ray. TPN catheter is not use for blood draws or the administration of other medications or fluids. TPN is always delivered via electronic infusion device. Solutions should be stored under refrigerator. TPN solution is changed every 24 hours.

F. Nursing Interventions 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Maintain aseptic technique. Monitor vital signs. Monitor weight, intake and output daily. Monitor site for redness, swelling, tenderness or drainage. Monitor urine for sugar and acetone four times per day. Electrolytes, glucose and blood urea nitrogen (BUN) are monitored as prescribed. Monitor rate hourly. If sepsis is suspected, a blood culture will be drawn, and the tip of the catheter will be cultured for bacteria. Monitor rate hourly. If sepsis is suspected, a blood culture will be drawn and the tip of the catheter will be cultured for bacteria. Monitor for signs of fluid overload such as bounding pulse, jugular vein distention, headache, increased blood pressure, and lung crackles. 12. Keep tubing connections taped. 13. If the intravenous (IV) tubing disconnects, instruct the patient to perform the valsalva maneuver.

64

14. Monitor for the signs of an air embolous such as confusion, pallor, light-unresponsiveness. 15. Place the patient in the left side-lying position with the head lower than the feet if air embolism is suspected and contact the physician. G. Fat Emulsion 1. 2. 3. Assess for allergy to eggs, a contraindication for lipid infusion. Administer slowly for the first 15 to 30 minutes and monitor the patient for adverse reactions such as dyspnea, cyanosis and allergic responses. Monitor for signs and symptoms of fat overload, which include fever, leukocytosis, hyperlipidemia, pruritic urticaria and possibly.

MEAL PLANNING Planning meals includes not only the listing of food to serve at any one meal, known as the menu, but also these considerable factors. FACTORS TO CONSIDER IN PLANNING MEALS

1. Nutritional adequacy or the provision of palatable foods that is rich in essential nutrients. Nutrition needs of an
individual is affected by age, sex, body built and activities engage in by the individual.

65

2. Aesthetic and Psychological aspects of food or the proper combination of flavor, texture and shapes as well as
variety in color, form and arrangement.

3. Suitable, Availability and Quality of food to be served – The flavor to be prepared must be in season and should be
possessing essential organic and non-organic substances considering the health condition and ages of the family members.

4. The food budget – The food budget is influenced by the family income; knowledge of the family market shopper’s
shopping skills, family food likes and dislikes and their goals and values.

5. Differences in Food Habits – These includes the dietary habits of nationality groups, religion food pattern, cultural
and religious food pattern and the socioeconomic background.

6. The Time and Skill in Planning Meals – The length of meal preparation, the amount of experience and the time
available are to be considered.

7. Physiological Aspects – The meal to be prepared must be based on the health status of each member of the family,
like therapeutic diet.

8. Equipment available for food preparation – It must be clean and in variation.
PRINCIPLES IN PLANNING MEALS

66

CONVENTIONAL MEAL a. b. c. d. e. f. g. h. i. j. k. Plan several days’ meals at one tome, utilizing simple meals that are easy to prepare and serve. Include more of one-dish meals like “sinigang”, “nilaga”, “tinola”, sautéed vegetable with serving portion of meat. Plan dishes that do not entail too much preparation at one time. If possible, preparation is done the day before dish is served. Plan meals that have interesting variety in color, texture, and flavor. Plan to serve foods that are not only in season but also enjoyed by the diner. Consider palatable foods that are rich in essential nutrients. Consult the different food groups. Make out a market list to avoid extra trips to the food stores. Check and see if all ingredients are available and equipment are in good working condition. Avoid dishes requiring last minute attention in one meal. Utilized leftover or meats that require a short time to cook. Serve simple dessert.

ECONOMIC MEAL BETTER BUYING PRACTICES a. Before purchasing, plan the menu for nutrient adequacy, variety and flexibility and make a shopping list.

67

b. c. d. e.

Compare prices among market place, groceries, between fresh and canned goods, between one brand and another, between cuts of meats, between cuts of meats, between whole and ready-made items. Know how much money you have to spend. Avoid impulse buying by not shopping when you are tired or in a hurry, by reading label, by knowing specification of food products. Choose foods that are available and in season.

PROPER FOOD STORAGE a. b. c. d. Food items should be stored properly to protect them from contamination and to preserve their flavor, food value and appearance. Plan your menu in such a way that fresh items are served on marketing days such as vegetables and fruits and salads. Keep meat, fish poultry, vegetable and some fruits in refrigerator, loosely covered. Plan to use them as soon as possible or freeze them. Store dried beans, cereals, and root crops in cool dry places where there is air circulation. Keep them away from animals such as rodents, roaches and ants.

BENEFITS OF MEAL PLANNING 1. Composing menu and shopping list and drafting plans for preparing and serving meals save time and energy in shopping. Cooking, and planning each meal. Keeping the plans from week to week because each old plan is evaluated in the light of its merits and gives ideas of new plans.

68

2. 3. 4. 5.

Precise planning made it easier to control the expenditure of money because meals planned in the market on the spur of the moment tends to be costly. Planning for meals is to achieve the goal of good nutrition. Meals planned on the spur of the moment may or may not provide for good nutrition. Planned meals include a wider variety of food than meals hurriedly compose and prepared. It is proven to be the needed stimuli for people with poor appetite and lack of interest in eating Planning meals is to help from good planning habits. Experience in deciding what to serve, how much to spend, and how much time and energy to invest in meals favors the development of good judgment in meal management.

FOOD PREPARATION It has been proven by experiments that there can be considerable nutritive loss in food after processing and cooking., and too long holding after cooking. FACTORS THAT AFFECT NUTRIENT RETENTION DURING FOOD PREPARATION 1. pH CHANGES In general, most nutrients are stable at pH neutral medium except Ascorbic Acid (Vit. C), Folic Acid, (Vit. B9), and Thiamin (Vit. B1). Folic acid can be stabilized by an alkaline medium, while for ascorbic acid and thiamin, alkalinity even in slight degree is distinctly destructive.

69

2.

OXIDATION Pigments in food like tannin in fruits like mangoes and carotene in yellow vegetable like squash and carrots oxidize upon exposure to air causing darkening and decrease in nutritive value The formation of metmyoglobin or pigments in beef is accelerated at high humidity and lower air velocity attributes to the stimulated bacterial growth under these condition.

3.

LIGHT Among the amino acids, only trytophan is affected by light and the rest are relatively stable.

4.

HEAT Food is cooked to bring about desirable result namely:  To kill microorganism and parasites.  To destroy anti-digestive factors especially in beans, peas, cereals making this food utilizing by man.  To inactive or destroy enzymes which is found in certain fishes that have anti-thiamine factors, or in fruits and vegetables to halt the action of maturing enzymes.  To prolong shelf life or to preserve the food.  To soften tissue, bones and cellulose.  To bring out color and flavor changes and develop a more palatable products.

70

 5.

To have variety in food preparation which makes eating an art.

DRYING New techniques of drying such as puff drying freeze during and foam-mat drying in insignificant nutrient losses except in Vit. C.

6.

COLD STORAGE AND FREEZING Nutrient looses are insignificant during refrigeration and freezing as long as the food are properly processed, well packed and correct temperature steadily maintained. PRACTICAL GUIDES TO CONSERVE NUTRIENTS IN FOOD PREPARATION

After a general review of the affects of various factors and conditions on nutrients, the following hints on proper selection, preparation and service of food should be useful to fundamentals of nutrient ion. 1. 2. 3. 4. 5. Select fresh fruits and vegetables at the right maturing and buy the peak of the seasons. Buy products that needed refrigeration but do not store it long in the refrigerator. Nutrients are found in the skin or just beneath the skin of the fruits like apple and banana and other foods like peanuts and carrots. Prepare fruits and vegetables at the time needed. Avoid long exposure to air or light. Minimize soaking in water to prevent darkening of certain fruits and vegetable that decrease or diminish the nutrient contents.

71

6.

In preparing vegetables and fruits, keep skin intact. When cooking in water, they should be prepared with minimum heat as to preserve the delicate flavors present in the form of volatile compounds. 7. Look for the shorter possible time. Avoid stirring and keep pan covered except for some greens and strong flavored vegetables. 8. Use dripping of meats and fish. Dry heat method for meat is preferable. Boiling and baking result in less thiamine loss compared to long stewing. 9. Avoid overheating fats and reusing cooking oil many times, twice enough. 10. The shorter the time between cooking and serving the more nutrients ingested.

DISEASES, THEIR DEFINITIONS, CAUSES, SYMPTOMS, and NURSING DIET MANAGEMENT ENDOCRINE DISEASE DIABETES MELLITUS * Diabetes Mellitus is a chronic disease characterized by elevated blood glucose • Normal Physiology After ingestion of food, blood glucose levels rise. This rise in glucose signals the b-cells in the Islets of the Langerhans of the pancreas to secrete insulin. Insulin binds with insulin receptors in the blood stream and enables the cells to absorb glucose. This makes blood glucose normal. The cells break down some of the glucose to energy. The rest are converted to fat and stored in the cells. • 1. • • 2 Types of Diabetes Type I – Insulin dependent diabetes mellitus (IDDM) is characterized by lack of insulin secretion (without insulin, serum glucose level increases, and all cells are unable to use glucose for energy. Glucose is then spilled into the urine. Exact Cause – Unknown Possible cause – Viral infection

73



Symptoms: Itchy skin Poor wound healing If left untreated will Untreated ill lead to ketosis or ketonsidosis that may lead to death

Polyuria Polydipsia Polyphagia Rapid weight loss Muscle wasting Fatigue Weakness Irritability • • •

Goal of Diabetic treatment – to achieve metabolic control as near normal possible - to prevent onset of complications. Diet management Objectives: To maintain weight To avoid hypoglycemia To match calorie intake an expenditure with insulin therapy (budget)

74

1. 2.

Meals and snacks must be consistent in number, timing, and composition daily to avoid hypoglycemia (patient is taking insulin) Need extra food to avoid hypoglycemia depending on the activity Example: each hour of moderate exercise – 1 serving of fruit Each hour of vigorous exercise – 2 serving of fruit or 2 servings of bread

3. 4. 5. 6.

Need to eat sources of protein and fat to slow down the digestion and absorption of carbohydrates Must carry with him hard candy or sugar cubes at all times for unexpectedly delayed meal. Food does not have to be prepared separately from the rest of the family. Just don’t add extra sugar and fat. Remove skin from chicken. Diabetic diet

2) Type II – insulin dependent - it is characterized by normal or above-normal insulin level - the delayed glucose – insulin response • • Contributing factor - obesity Signs and symptoms 1. 2. Drowsiness Fatigue

75

3. 4. •

Blurred vision Tingling or numbness of the extremities

Diet Management

* Goal – to attain normal blood glucose levels through weight reduction 1. Low calories diet until blood sugar is controlled maintain normal weight - decrease weight, if obese 2. 3. 4. Low cholesterol to reduce risk of cardiac arrest. Meal spacing – 4 to 5 hours apart to allow postprandial glucose levels return to normal. Diabetic diet

Cardiovascular diseases 1. 2. 3. Atherosclerosis Hypertension Congestive heart failure ATHEROSCLEROSIS – it is formation of plagues, mostly of fat, blood components, and connective tissue at the arterial walls.

I.

76

With the accumulation of fats in the arterial wall, plaques develop that narrow the artery that restricts the flow of blood. These plaques may become so large that will totally occlude the artery. Narrowed blood vessels will reduce blood flow thereby reducing the flow of oxygen to the tissues and organs. This will result in damage to the tissues and organs. • 3 most common afflicted by atherosclerosis

a. legs b. brain – cerebral hemorrhage c. heart – coronary heart disease myocardial infarction may lead to death • Causes a. b. c. d. • Familial hypercholesterolemia – caused by defective genes Diet Various diseases Drugs

advanced collagen disease

Diet Management 1) a) For weight loss – decrease weight b) For overweight – reduce sodium intake between 2 to 4 g to promote a drop in blood pressure. c) Acute care setting l- initial restricted sodium intake is 200 to 250 mg a day. 2) Adjust potassium intake; depending on dry therapy 3) Modify fat intake by: a) increasing polyunsaturated fat b) decreasing saturated fats 4) Discourage alcohol intake and limit caffeine containing beverages to 3 to 4 cups a day. 5) Monitor fluid and electrolyte balance of diuretics used

III.

CONGESTIVE HEART FAILURE it is syndrome characterized by the inability of the heart to maintain adequate blood flow through the circulatory system. Leads to decreased blood flow to the kidneys, excessive sodium and fluid retention, peripheral and pulmonary edema, overworked and enlarged heart.



Causes 1. All organic heart diseases like MI, HPN, OMP, etc. 2. Circulatory overload related to excessive IV fluids or renal failure. 3. Circulatory deficit such as hemorrhage and dehydration and pulmonary diseases

Diet Management

Objective: - To reduce sodium and fluid retention - minimize cardiac overload 1. 2. 3. 4. 5. Limit sodium intake Decrease calories for weight loss Provide 5 to 6 meals a day of non-irritant and non-gas forming food limit gastric distention and pressure on the heart. Fluids are limited to 3 liters depending on the clients response to sodium restriction. Caffeine-free drinks.

RENAL DISEASE I. • CHRONIC RENAL FAILURE It is a progressive loss of renal function related to irreversible nephron deterioration.

3 PHASES OF CHRONIC RENAL FAILURE

81

1) Decreased renal function – there is a 50% reduction in the glomerular filtration rate. It is a symtomatic. 2) Renal insufficiency – the general filtration rate decreased by 70-75 • Signs and symptoms 1. Creatinine; blood urea nitrogen levels rise 2. Urine becomes more dilute 3. Mild anemia develops 4. Asymptomatic because the remaining nephrons become hypertrophic to maintain homeostatis 3) Renal failure 80-85% of renal function is lost. Increase in serum createnine • Cause / Predisposing Factor 1. Chronic glomerulonephritis 2. Polycystic disease 3. Chronic pyelonephritis 4. Urinary tract obstruction 5. Infection 6. Poor circulation related to atherosclerosis heart failure 7. Drugs 8. Nephrotoxic agents 9. Dehydration 10. Others • Diet Management 1. LOW PROTEIN, LOW PHOSPHORUS, HIGH CHO, HIGH FAT

82

2. 3. 4. 5. 6. 7. 8. 9.

Adjust and modify protein intake to promote nitrogen balance while maintaining BUN levels below 6090 mg/day Approximately 2/3 of total protein; should be from high biologic source. Provide adequate non protein calories is needed when protein is restricted to prevent the use of distance protein for energy, prevent tissue catabolism. Maintain and restore ideal weight. Obese clients may require fewer calories Limit sodium intake to 2.0-3.0 If sodium retention is present (sudden weight loss, hypertension, symptoms of heart failure), restrict fluid urine output + 500 ml for insensible losses. Moderately restrict potassium intake to prevent hyperkalemia to 1.5 to 2.8/day. Actual requirements are based on urine and serum levels of potassium.

II. ACUTE RENAL FAILURE a) decrease in renal blood flow b) glomerular or tubular damage leading to sudden loss of renal function and oliguria • Phases

1) Oliguria – low urine output of less than 400-600 in 24 hours which may deteriorate to anurea. high-output renal failure-large amounts of urine are extracted deposit loss of renal function and nitrogenous wastes 2) Diuretic phase – the kidneys are unable to conserve water

83

urine volume may double daily until a fixed amount is reached loss of fluid, sodium and potassium are extensive last for 14-21 days 3) Recovery phase – there is gradual improvement in kidney function over 3 to 12 months period. • a) b) c) d) e) f) g) h) a) b) c) d) Pre – natal causes: decreased renal blood flow related to:

Shock Trauma Hemorrhage Surgery Burn Hypertension Serum dehydration Heart failure • Intra-renal causes: nephron damage due to: Nephrotoxins Autoimmune diseases Infections Acute glomerulonephritis • Post-renal etiologies: obstructed urine outlow due from kidneys due to benign prostatic hypertrophy, bladder or prostate cancer

84

a) Calculi b) Trauma c) Medications • Diet Management

Objective: To lesson workload of the kidneys and restore optimal nutritional status 1) Adjust protein intake according to renal function. Initially, parental solutions of amino acid and glucose maybe given if client is unable to eat. Protein allowance may begin at 0.8g/ body weight and increase as renal function improves. 2) Increase calorie intake to approximately 50 cal/kg to promote nitrogen balance and replenish losses. Adjust fluid intake to avoid overhydration. Allow output + 500 ml/day. 3) Adjust sodium intake according to urine output, serum sodium level, symptoms of sodium imbalance, and concurrent use of dialysis. Sodium intake may be restricted to 500-100 mg/day. During the oliguria phase sodium requirement increase during diuretic the anuric phase liberalized during the diuretic phase. Provide small, frequent meals and assistance with eating, as needed for clients receiving an oral diet and are weak or fatigued. • • a) b) c) d) Instruct the client and family of the principles and rationale of diet management Monitor the compliance with the diet and follow diet counseling effectiveness of the diet the evaluation of the need for diet modification observe changes in weight, the intake and output in over 24-48 hour periods.

III. UROLITHIASIS

85

- Formation of stones n the urinary system • Causes a. b. c. d. e. f. g. idiopathic infections urinary stasis metabolic abnormalities hormone imbalance inadequate fluid intake leads to concentrated urine output symptoms depend on the site of stones 1. nausea 2. vomiting 3. diarrhea 4. abdominal pain



Bladder stones 1. chills 2. fever 3. dyssuria Renal Pelvic Stones a. Renal colic b. Severe pain that radiates down the urinary tract accompanied by sweating, pallor, nausea, vomiting and possible abdominal pain and diarrhea

Diet Management 1) Calcium phosphate stones increase fluid intake to 3 to 41/daily avoid excessive protein intake increase intake of acid-forming food

87

2) Calcium oxate stones avoid foods high in oxate, ex. Eggplant, okra, parsley, peppers avoid Vitamin C supplements, they increase oxalate excretion

3) Magnesium ammonium phosphate stone - increase intake of acid-forming foods 4) Cystine stones 5) Uric acid stones 6) Urinary tract infection Foods lacking in Oxalate that should be avoided: Beets Celery Eggplant Dandelions Peppers-green Sweet potatoes Spinach Soy bean Draft beer Tea Currents Wheat germ Cocoa/ovaltine Red grape Rhubarb increase fluid intake increase intake of base-forming foods low purine diet increase intake of base-forming foods diets low in methonine and protein
