NUR 372 CLASS 3 NUTRITION/FEEDING Flashcards
NUTRITION
- provides energy for cellular metabolism and repair, organ function, growth and physical activity
NUTRIENT DENSITY
- ratio of nutrient content to total energy content
ENERGY BALANCE
- equal expenditure of calories in and out
CARBOHYDRATES
- provide energy, assist in fat metabolism, and production of amino acids
- ex: bread, cereal, rice.
PROTEINS
- vital to growth, development, and normal function of all body systems
- ex: meat, fish, poultry, milk, cheese, and eggs.
FATS
- provide cellular transport, insulation, protection of vital organs, and energy storage
- ex: animal and vegetable fats.
IDEAL BODY WEIGHT
- optimal weight for body health and frame size
FACTORS AFFECTING NUTRITION
- physiologic factors
- psychological State
- lifestyle, habits, and economic resources
- culture and beliefs
- drug and nutrient interactions
- gender
- illnesses and treatment, surgery
- alcohol and drug abuse
- exercise
AGING ADULT NURSING CONSIDERATIONS
- metabolic rate declines with age
- need for calories decreases, but not for vitamins and minerals
- hunger and thirst decrease
- diets are often deficient in proteins.
- need fiber to prevent constipation
- sense of taste and smell diminish.
- decreased peristalsis and blood flow to GI tract
- impaired dentition, decreased sense of thirst, and decreases saliva production.
MANIFESTATIONS OF ALTERED NUTRITION
- overweight: 25 – 29.9
- obesity: > 30
- underweight: <18.5
recent significant weight loss or gain - decreased Energy
- altered bowel patterns
- altered skin, teeth, hair, and mucous membranes
FLUID VOLUME DEFICIT CAUSES
- hypovolemia/dehydration
- GI losses (diarrhea, vomiting)
- hemorrhage
- skin losses (fever, sweating a lot)
- altered intake (not drinking enough)
FLUID VOLUME DEFICIT SUBJECTIVE ASSESSMENT SIGNS
- dizziness
- weakness
- fatigue
FLUID VOLUME DEFICIT OBJECTIVE ASSESSMENT SIGNS
- tachycardia
- hypotension
- dry mucous membranes
- skin turgor
- weight loss
- oliguria
- older: drowsiness, confusion
FLUID VOLUME EXCESS CAUSES
- hypervolemia/overhydration
- kidney failure
- heart failure
- cirrhosis
- fluid leaking out of the vascular system into the tissues
FLUID VOLUME EXCESS SUBJECTIVE ASSESSMENT SIGNS
- weight gain
- swelling
- SOB
FLUID VOLUME EXCESS OBJECTIVE ASSESSMENT SIGNS
- tachycardia
- hypertension
- ascites
- crackles
- edema
- distended neck veins
- daily weight most reliable indicator of fluid volume increase/decrease
SUBJECTIVE DATA COLLECTED IN NUTRITIONAL ASSESSMENT

CLEAR LIQUID DIET
- liquid at room temperature
