25
Critical goal in the early stages of treatment for anorexia nervosa is
allow person a feeling of control over her life
26
Bulimia nervosa patients often have a problem with:
an inability to control responses to impulse and desire
27
Complications of Bulimia in someone who purges
Ulcers, pitting of the teeth, and electrolyte imbalance
28
Pica =
Repeated consumption of non-nutritive items, such as paper, clay, laundary starch, paint chips
29
False about eating disorders
Males are not affected
30
Characteristic that differentiates anorexics from bulimics
Denies need for treatment
31
Functions of water
Transport medium Lubrication Temperature regulation Constriction / dilation of capillaries Perspiration
32
Water does not require any digestion
True
33
Osmosis
Movement of water from an area of low salt concentration to an area of high solute concentration through a membrane
34
What solutes influence osmosis
Electrolytes (sodium, potassium, and chloride) Protein
35
How do we excrete water?
Kidney - urine GI tract - feces Skin - sweat Insensible losses - drying of skin, moisture lost through breathing
36
How many liters are lost daily
2-3 liters \*Can change based on activity, temperature, and humidity\*
37
Oral rehydration therapy
The act of providing water and electrolytes to reverse dehydration
38
Water-soluble vitamins
Vitamin C, B vitamins Readily excreted in H2O Not stored Not toxic Defficiencies quickly onset due to high excretion
39
Fat-soluble vitamins
A, D, E, K Not readily excreted Stored in the body (fat, liver, skin) Highly toxic Deficiencies develop slowly due to high storage levels
40
Vitamins are _______ while minerals are \_\_\_\_\_\_\_\_\_
organic, inorganic
41
Minerals only come from the environment
True
42
Vitamins can be created by plants and animals
TRUE
43
Block absorption of vitamins and minerals?
Phytic acid
44
Increasing abosrption of vitamins and minerals
MFP factor - meat, fish, and poultry Vitamin C Iron
45
Major Minerals
Bone - calcium, phosphorus, and magnesium Electrolytes - sodium, potassium, and chloride Protein - sulfur amino acids
46
Trace Minerals
Iron, copper, zinc, iodine, and selenium
47
Zinc
Cell replication and division - would healing Defiency - poor growth and would healing, poor immune response
48
Iron
Component of myoglobin (hemoglobin) Development of myelin sheath, neurotransmitters
49
Vitamin B12
Production of myelin sheaths Activation of folate Deficiency = from lack of intrinsic factor - leads to severe neurological problems and pernicious anemia
50
Folate
Deficiency leads to neural tube defects (spina bifida), and improper DNA synthesis
51
Potassium
Positive intracellular ion that helps conduct muscle and nerve impulses Defiency = leads to weakness, arrhythmia, excessive sweating, and eating disorders
52
Sodium
Positive extracellular ion Exchange for potassium in nerve cells
53
Calcium
Large component of bone Required for muscle contraction
54
Chromium
Aids in insulin binding to the cell to aid in the absorption of glucose and AA
55
Pyridoxine (B6)
Synthesis of non-essential AA, neurotransmitters
56
Vitamin C
Synthesis of collagen, and connective tissue Deficiency leads to scurvy
57
Antioxidants
Protect against oxidative damage from free radicals Vitamins = C, A, E Mineral = selenium
58
Beta-carotene
is a vitamin A provitamin
59
Erythropoiesis
The formation of red blood cells
60
Hemoglobin
Transports oxygen to the body and delivers it to myoglobin, where it exchanges oxygen for carbon dioxide
61
Macrocytic or Megaloblastic anemia
Improper DNA synthesis from a folate deficiency leads to a decreased cell division and enlearged red blood cells called these
62
Deficiency in Iron
most common form of anemia most common nutrient deficiency most toxic mineral
63
Ferritin
Storage protein for Iron
64
Transferrin
The transport protein involved in delivering iron to the body
65
Iron needs are increased in this population
Premenopausla women because of increased iron lost during mensturation
66
Vitamin K (required)
required for blood clotting as it is a coenzyme in the formation of prothrombin
67
Anticoagulants
Aid in reducing this clotting mechanism by vitamin K inhibition ex. warfarin
68
Major minerals in descnding order of concentration
Calcium Phosphorus Magnesium Sodium Potassium Chloride Sulfur
69
Top four trace minerals in descending order
Iron Copper zinc Iodine
