Nutrition (Exam 3) Flashcards
Nutrition is..
the study of food, how it affects the human body, how it influences health, and how the body metabolizes food for energy
How do nurses improve nutritional care?
- screening and assessing nutritional status
- appropriate and timely referrals (registered dietician)
- patient education
- monitoring and evaluation of nursing interventions

list of objectives and goals geared towards improving quality of life and eliminating health disparities
Carbohydrates
chief source of energy in the body that includes simple sugars, starches, and cellulose which convert into glucose
Fats
most concentrated form of energy
carriers for the fat-soluble vitamins A, D, E, and K
Proteins
when broken down, contain 20 amino acids
necessary for growth and development and used for tissue repair and maintenance and a source of energy
Vitamins
organic food substances that are essential for growth, functioning of body processes and maintenance
Minerals
inorganic substances essential to metabolic processes
Anthropometric Measurements
weight history
BMI (18.5-24.9)
waist circumference
body composition (skin fold measurement)
Blood glucose lab tests
indicates the amount of fuel available for cellular energy
Serum albumin/prealbumin lab tests
synthesized in liver, indicates malnutrition and malabsorption
Creatine lab tests
indicator of renal function
Factors that affect nutrition
developmental stage (infants and children, pregnancy)
educational level
knowledge of nutrition
lifestyle choices (dietary patterns, veganism, dieting)
ethnicity and culture
religious practices
disease processes
Medical Nutritional Therapy
use of therapeutic diets, guidelines, and nutrients to treat an illness or medical condition
Weight Management: Obesity
BMI over 30
calorie reduction of 500 to 1000 kilocalories per day (can be done by limiting foods high in fat and empty calories, smaller portion sizes should be emphasized)
encourage exercise/lifestyle changes
weigh weekly; suggest food diary
Weight Management: Undernutrition
encourage client to seek counseling for
eating disorder
improve appetite
enteral or Parenteral nutrition
Coronary Heart Disease
decrease saturated fat and cholesterol (margarine, poultry with skin, fatty meats, frying, sauces, whole fat dairy)
Hypertension
decrease sodium, saturated fats, and cholesterol intake (packaged, processed foods)
DASH diet: Dietary Approaches to Stop Hypertension (emphasis on fruits, veggies, nuts, and low-fat dairy product)
Heart Failure
decrease sodium intake (reduce extracellular fluid and cardiac workload, cardiac cachexia-advanced heart failure)
Diabetes Mellitus
individualized diet; mindful of carbs and concentrated sweets high in white sugar
high fiber fruits and veggies and whole grains and protein for feeling full(low glycemic index-measures how carb containing food raises blood glucose)
Dysphagia
difficulty swallowing; can lead to aspiration, dehydration, and weight loss
signs include drooling, pocketing of food, coughing while eating
pureed & mechanical soft diet, thicken liquids, NPO diet
GERD
the return of the stomach’s contents back up into the esophagus
limit foods that irritate esophagus like tomato, spicy, and citrus
limit foods that decrease LES (lower esophageal sphincter) like fat, alcohol, caffeine, chocolate
IBD/IBS
focus of treatment is on correcting malnutrition and loss of nutrients
low residue when flare up
