Vitamin C
Vitamin B12
Vitamin D
Vitamin B6
Which of the following best describes the solubility difference between fat-soluble and water-soluble vitamins?
Fat-soluble vitamins dissolve in water, while water-soluble vitamins dissolve in fat.
Fat-soluble vitamins dissolve in fat, while water-soluble vitamins dissolve in water.
Both dissolve only in fat.
Both dissolve only in water.
A patient presents with symptoms of easy bruising and excessive bleeding. Which fat-soluble vitamin deficiency is most likely responsible, and what is its primary dietary source?
Vitamin K; leafy green vegetables
Vitamin D; citrus fruits
Vitamin A; dairy products
Vitamin E; whole grains
A person following a strict vegan diet is at risk for deficiency in which water-soluble vitamin, and what metabolic process does this vitamin support?
Vitamin C; collagen synthesis
Vitamin B12; red blood cell formation
Vitamin B6; amino acid metabolism
Vitamin B1; carbohydrate metabolism
Explain why fat-soluble vitamins are more likely to cause toxicity than water-soluble vitamins when consumed in excess.
Because they are stored in body fat and not readily excreted.
Because they are destroyed by cooking.
Because they are not absorbed by the body.
Because they are only found in animal products.
A patient with a history of chronic alcoholism is found to have neurological symptoms. Which water-soluble vitamin deficiency is most likely, and what is its role in metabolism?
Vitamin C; antioxidant function
Vitamin B1 (Thiamine); carbohydrate metabolism
Vitamin D; calcium absorption
Vitamin K; blood clotting
Compare the storage and excretion patterns of fat-soluble and water-soluble vitamins and explain how this affects the risk of toxicity.
Fat-soluble vitamins are stored in the liver and fatty tissues, increasing toxicity risk; water-soluble vitamins are excreted in urine, lowering toxicity risk.
Both are stored in the liver, so both have high toxicity risk.
Water-soluble vitamins are stored in fat, increasing toxicity risk.
Fat-soluble vitamins are excreted in urine, lowering toxicity risk.
A person has a diet lacking in citrus fruits and green vegetables. Which vitamin deficiency are they most at risk for, and what are the potential effects?
Vitamin D; rickets
Vitamin C; scurvy
Vitamin A; night blindness
Vitamin K; poor blood clotting
A patient is diagnosed with osteoporosis. Which fat-soluble vitamin deficiency could contribute to this condition, and what is its role in bone health?
Vitamin D; promotes calcium absorption
Vitamin E; acts as an antioxidant
Vitamin K; supports vision
Vitamin A; aids in immune function
Explain how the absorption of fat-soluble vitamins can be impaired in individuals with certain digestive disorders, such as celiac disease or cystic fibrosis.
These disorders reduce fat absorption, which is necessary for fat-soluble vitamin uptake.
These disorders increase water absorption, which affects vitamin solubility.
These disorders increase bile production, enhancing vitamin absorption.
These disorders only affect protein absorption.
A person consumes a diet high in processed foods and low in fresh fruits and vegetables. Which water-soluble vitamin deficiency might they develop, and what is a likely symptom?
Vitamin B12; anemia
Vitamin C; bleeding gums
Vitamin D; bone pain
Vitamin K; easy bruising
A patient is taking a medication that inhibits fat absorption. Predict which group of vitamins they are at risk of becoming deficient in and justify your answer.
Water-soluble vitamins, because they require fat for absorption.
Fat-soluble vitamins, because their absorption depends on dietary fat.
Both, because all vitamins require fat for absorption.
Neither, because vitamins are absorbed independently of fat.

Fruits, Milk, Vitamins, Water, Pork, and Vitamins
Carbohydrates, Fats, Water, Protein, Minerals and Vitamins
Carbohydrates, Fats, Minerals, Cheese, Protein, and Vegetables
