Q

minerals

A

inorganic elements essential to the body as catalysts in biochemical reactions

23
Q

What is the primary absorption site for nutrients?

A

the small intestine

24
Q

how does the body absorb nutrients?

A

by means of passive diffusion, osmosis, active transport, and pinocytosis

25
Q

Where does the absorption of carbohydrates, protein, minerals, and water-soluble vitamins occur?

A

small intestine

26
Q

What organ processes carbohydrates, proteins, minerals, and water-soluble vitamins after they are absorbed in the small intestine?

A

the liver

27
Q

approximately how much of water is absorbed in the small intestine?

A

85-90%

28
Q

What is an example of nursing diagnoses relating to nutrition?

A
  • risk for aspiration
  • readiness for enhanced nutrition
  • deficient knowledge
  • impaired swallowing
  • diarrhea
29
Q

Goals and outcome relating to nutrition:

A

reflect patients physiological, therapeutic, and individualized needs

30
Q

metabolism

A

all biochemical reactions within the cells of the body

31
Q

anabolism

A

building of more complex biochemical substances by synthesis of nutrients

32
Q

catabolism

A

breakdown of biochemical substances into simpler substances; occurs during physiological states of negative nitrogen balance.

33
Q

What are some examples of health promotion?

A
  • education
  • early ID of potential or actual problems
  • meal planning
  • weight loss plans
  • food safety (as food gets cold, bacteria starts to grow)
34
Q

When is normal metabolism and anabolism are physiologically possible?

A

when the body is in positive nitrogen balance.

35
Q

What are the three main processes of nutrient metabolism?

A
  1. catabolism of glycogen into glucose, carbon dioxide, and water (glycogenolysis)
  2. anabolism of glucose into glycogen for storage (glycogenesis)
  3. catabolism of amino acids and glycerol into glucose for energy (gluconeogenesis)
36
Q

Where is protein stored?

A

in muscle mass

37
Q

What is the major form of body reserve energy?

A

fat - stored as adipose tissue

38
Q

What factors influence nutrition?

A
  • environmental factors

- developmental needs

39
Q

enteral tube feeding

A

a type of feeding that provides nutrients directly into the GI tract.

40
Q

When is enteral tube feeding appropriate?

A

when patients are unable to ingest food but are still able to digest and absorb nutrients (has a functioning GI tract)

41
Q

When is jejunal feeding preferred over gastric feedings?

A

if there is a risk for gastric reflux which leads to aspiration

42
Q

What do you avoid during treatment for peptic ulcers?

A
  • caffeine
  • spicy foods
  • aspirin, nonsteroidl anti-inflammatory drugs (NSAIDs)
43
Q

polymeric formula

A

milk-based, blenderized (the patent’s GI tract needs to be able to absorb whole nutrients

44
Q

Modular formula

A

single-macronutrient (protein, glucose, polymers, or lipids)

45
Q

Elemental formula

A

predigested nutrients (easier for partially dysfunctional GI tracts to absorb)

46
Q

Specialty formulas

A

designed to meet specific nutritional needs in certain illnesses

47
Q

What is the treatment for type 1 diabetes mellitus?

A

insulin and dietary restrictions

48
Q

What is the treatment for type 2 diabetes mellitus?

A

exercise and diet therapy initially.

49
Q

What are the diet guidelines for Diabetes 2?

A
  • individualized diet
  • carbohydrate consistency and monitoring
  • saturated fat less than 7%
  • cholesterol intake less than 200 mg/dL
  • protein intake 15-20% of diet
50
Q

parenteral nutrition

A

a form of specialized nutrition support provided intravenously

51
Q

Type 1 diabetes

A

body produces no insulin

52
Q

type 2 diagetes

A

body produces very little insulin

53
Q

two types of carbohydrates

A

simple - sugars

complex - good carbs

54
Q

What is the most important minerals that helps support tissue damage?

A

protein, vitamin C and zinc (wound care)
