Book Ch. 28 ATI Ch. 39 & 54, also used green Nutrition ATI book
What is the goal of “Healthy People 2020”?
To promote health & reduction of chronic diseases associated with diet & weight.
How can nurses serve patients regarding their views on nutrition?
- Nurses should encourage favorable nutrition choices.
- Nurses can serve as informational resources for patients regarding health guidelines for healthy eating.
- Nurses should considers & incorporate the family’s nutritional habits to a patient’s individual plan of care.
What are 2 established guidelines for healthy eating that patients & nurses can refer to?
- Dietary Guidelines for Americans
2. MyPlate.gov
Describe the 5 color categories used in MyPlate.
Used to illustrate a healthy meal:
- red - fruits
- green - veggies
- orange - grains
- purple - protein
- blue - dairy
MyPlate promotes healthy nutrition based on what?
USDA dietary guidelines for Americans 2015-2020:
- Food choices & variety
- Portion size
- Activity
- Tools for a successful nutritional lifestyle
Define Nutrition.
- Study of food & how it affects the body & influences health.
- Adequate nutrition is essential to wellness.
Define Nutrients.
- Building blocks for cells & tissues that:
- supply energy (macronutrients-kilocalories)
- help manufacture, maintain, & repair cells (micronutrients)
- Found in foods like carbs, proteins, & lipids.
- Are changed & used in the body through metabolism.
What are the different types of nutrients?
- Carbohydrates (4 kcal/gram)
- Proteins (4 kcal/gram)
- Lipids/Fats (9 kcal/gram)
- Micronutrients
- Macronutrients (supply the body with energy)
- Water
- Any one food can contain a variety of nutrients.
Describe Carbohydrates.
Primary energy source:
- Energy for muscle & organ function.
- Provide energy for the brain (average amount needed to fuel the brain in 130 g/day).
Sugars:
- Store glucose in liver & skeletal muscle tissue as glycogen.
- Glycogen converted back into glucose to meet energy needs.
Describe Proteins.
- Essential for tissue growth, maintenance, & repair of body cells & tissues.
- Nitrogen Balance: intake & output are equal.
- Positive Nitrogen Balance - intake > output
- Negative Nitrogen Balance - intake < output
- Amino Acids: for protein synthesis to occur, every amino acid necessary to build that protein must be avaliable.
Describe Lipids.
- Lipids = Fats
- Solid at room temperature are called fats.
- Liquid at room temperature are called oils.
- Phospholipids are a key component of lipoproteins.
- Back-up Energy Source
- Organ Insulation & Protection
Describe Micronutrients.
- Needed only in small amounts.
- Vitamins & Minerals
- Critical in:
- Building & maintaining body tissues.
- Supporting our immune system so we can fight disease.
- Vitamins:
- Ensure healthy vision.
- Help our bodies break down & use the energy found in carbs, proteins, & lipids.
- Critical during periods of rapid growth, pregnancy, lactation, & healing.
- Minerals
- Inorganic elements found in nature.
- Major minerals - minerals the body needs in amounts of 100 mg/day or higher.
- Trace minerals - are essential but are in lower concentrations.
Describe Water.
- Makes up about 1/2 of total body weight.
- 55-65 % in men b/c of muscle mass.
- 50-55% in women.
- Transports Substances.
- Basic solvent for body’s chemical processes.
- Form for Tissues (Fills in Spaces)
- Maintains Body Temperature.
Define Energy Balance.
- Energy in nutrients measured in calories.
- Calories “in” must equal calories burned.
- Undernourished = too few calories in.
- Obesity = too many calories in.
- 2 Components:
1. Basal Metabolic Rate (BMR) - amount of energy required at rest in a neutral temperature environment.
2. Total Energy Needs - replacing calories used for BMR + physical activity.
What are factors that affect nutrition?
Hint there are 9 in total
- Developmental Stage (from infants to elders; lactating women; pregnancy & folic acid)
- Educational Level
- Knowledge of Nutrition
- Access to appropriate or adequate nutrition
- Lifestyle choices (dietary patterns; vegetarianism; dieting)
- Ethnicity/Culture
- Religious Practices
- Disease Processes (any illness, especially accompanied by fever, increases the need for protein, water, & calories to meet demands of an increased metabolic rate)
- Functional Limitations
Identify the client with the greatest risk for developing protein-calorie malnutrition.
A. A client who has MS & is in a wheelchair.
B. A client weighing 300 lbs. who has entered the hospital for cardiac bypass surgery.
C. A client with a broken arm & femur from trauma who is running a fever of 101.5 F (38.6 C).
D. A client who is of Native American heritage.
C. A client with a broken arm & femur from trauma who is running a fever of 101.5 F (38.6 C).
- B/c the client would have the greatest increase in metabolic demand for energy & nutrients & run the greatest risk for not having those energy demands met when they have a fever.
What are the 2 formulas to calculate BMI?
- Metric System
BMI = [weight (kg) / height (m squared)] - Imperial System
BMI = [weight (lbs.) / height (in. squared)] x 703
1 kg = ? lbs.?
2.2 lbs.
1 in. = ? cm.?
2.54 cm.
What are the steps to determine BMI using the metric system?
- Determine the client’s weight in kg & height in m.
- Multiply the client’s height by itself to determine the m squared value.
- Divide the weight in kg by the height value in step 2. The result is the BMI.
What are the classifications for weight in the US?
Underweight = BMI < 18.5 Normal Weight = BMI 18.6 - 24.9 Overweight = BMI 25.0 - 29.9 Obesity = BMI > 30 (3 classes of obesity) Class 1 = BMI 30.0 - 34.9 Class 2 = BMI 35.0 - 39.9 Class 3 = BMI > 40.0
What are the 3 types of eating disorders?
- Anorexia Nervosa - psychiatric disorder characterized by self-starvation.
- Bulimia Nervosa - binge eating followed by self-induced vomiting or laxative use to purge food.
- Binge-Eating Disorder - binge eating without purging.
What are some physical signs of eating disorders?
- Hair Loss
- Abnormal Weight Loss
- Cold Intolerance (they are always cold)
- Absent or Irregular Menstruation
- Low BP
- Weakness
- Atrophy of Breast Tissue
What is the first thing we need to do in managing imbalances?
Planning
- Must identify the etiology of the imbalance.
