NURS 171 Week 10: Fat Soluble Vitamins Flashcards
Vitamins
- can not be made by the body
- necessary for metabolism
- help in breakdown of nutrients or
- preventing a particular deficiency disease and chronic disease
- critical for building + maintaining body tissues
- supporting our immune system
- ensuring healthy vision
Fat- Soluble Vitamins
A, D, E, K
- stored in liver + adipose tissue
- E is deposited in all body tissue
- deficiencies seen in diseases affecting fat digestion + absorption
- deficiencies seen in diets with inadequate amounts
- toxicity is possible because they are not readily excreted
Fat Soluble: Vitamin A Function
- night + color vision
- cellular growth + maturity
- maintaining healthy skin + mucous membranes
- growth of skeletal + soft tissues
Fat Soluble: Vitamin A Sources
- butter
- cream
- egg yolk
- yellow fruit
- green leafy vegetables
Fat Soluble: Vitamin A Effects Of Deficiency
-night blindness
Fat Soluble: Vitamin A Symptoms of Excess
- GI Upset
- Headache
- Blurred Vision
Fat Soluble: Vitamin D Function
- regulates blood calcium levels
- regulates rate of deposit and resorption of calcium in blood
Fat Soluble: Vitamin D Sources
- fish liver oil
- fish
- fortified milk
- sunlight exposure
Fat Soluble: Vitamin D Effects of Deficiency
- bone + muscle pain
- weakness
- softening of bone
- fractures
- rickets
Fat Soluble: Vitamin E Function
antioxidant (protects cells against free radicals)
-deposited in all body tissues
Fat Soluble: Vitamin E Sources
- vegetable oils
- nuts
- milk
- eggs
- muscle meats
- fish
- wheat
- rice germ
- green leafy vegetables
Fat Soluble: Vitamin E Effects of Deficiency
- hyporelexia (below normal or absent reflexes)
- ataxia (impaired coordination)
- hemolytic anemia (RBC destroyed faster than made)
- myopathy (disease of muscle tissue)
Fat Soluble: Vitamin E Symptoms of Excess
- insufficient blood clotting
- impaired immune system
Fat Soluble: Vitamin K Function
- synthesis of clotting factors
- bone development
Fat Soluble: Vitamin K Sources
-green leafy vegetables
-liver
(intestinal bacteria synthesize a form of vitamin k, so deficiency is unlikely)
