1.
Without the presence of this vitamin your blood would be unable to clot.
Correct Answer
B. Vitamin K
Explanation
Vitamin K is responsible for blood clotting. Without it, the blood would not be able to clot properly, leading to excessive bleeding and difficulty in stopping bleeding from wounds or injuries. This vitamin plays a crucial role in the activation of proteins that are involved in the clotting process. Therefore, the absence of vitamin K would impair the body's ability to form blood clots, resulting in potential life-threatening situations.
2.
Vitamin D helps the body to absorb _______________________.
Correct Answer
A. Calcium
Explanation
Vitamin D helps the body to absorb calcium. Calcium is an essential mineral that is important for maintaining strong and healthy bones. Without sufficient levels of vitamin D, the body cannot effectively absorb calcium from the diet, leading to a deficiency. Vitamin D plays a crucial role in regulating calcium levels in the body and promoting its absorption from the intestines into the bloodstream. This is why it is often recommended to ensure an adequate intake of both vitamin D and calcium for optimal bone health.
3.
This antioxdant vitamin promotes good vision, especially in low light situations.
Correct Answer
D. Vitamin A
Explanation
Vitamin A is the correct answer because it is known to promote good vision, especially in low light situations. It plays a crucial role in the functioning of the retina and helps maintain the health of the cornea. It is also involved in the production of rhodopsin, a pigment in the eyes that enables vision in dim light. Vitamin A deficiency can lead to night blindness and other vision problems. Therefore, consuming enough vitamin A through diet or supplements is important for maintaining good vision, particularly in low light conditions.
4.
Vitamin E is important for the formation of ___________ and also helps the body make use of _________________.
Correct Answer
B. Red blood cells; vitamin K
Explanation
Vitamin E is essential for the formation of red blood cells, which are responsible for carrying oxygen throughout the body. Additionally, it helps the body utilize vitamin K, which is important for blood clotting and bone health.
5.
What are water-soluble vitamins?
Correct Answer
D. Vitamins that don't get stored in your body. They travel through your bloodstream. Whatever the body doesn't use comes out when you urinate.
Explanation
Water-soluble vitamins are not stored in the body and instead travel through the bloodstream. Whatever the body does not use is excreted through urine. This means that these vitamins need to be consumed regularly as they are not stored and can be easily eliminated from the body.
6.
What is true about fat-soluble vitamins?
Correct Answer
D. All of the above are correct.
Explanation
All of the statements mentioned about fat-soluble vitamins are true. Fat-soluble vitamins, including A, D, E, and K, are stored in the liver. They are also stored in body fat until the body requires them. Therefore, the correct answer is that all of the above statements are correct.
7.
What is the best way to make sure you are getting all the vitamins your body requires?
Correct Answer
A. Eat a healthy, well-balanced diet.
Explanation
Eating a healthy, well-balanced diet is the best way to ensure that you are getting all the vitamins your body requires. This means consuming a variety of foods from different food groups, including fruits, vegetables, whole grains, lean proteins, and healthy fats. These foods provide a wide range of essential vitamins and minerals that are necessary for optimal health. By following a balanced diet, you can meet your body's nutritional needs and support overall well-being. Weighing yourself daily and drinking water are important for overall health, but they do not specifically address the intake of vitamins.
8.
It is important for people who are taking warfarin (a blood-thinner) to consistently maintain their intake of this vitamin or foods containing this vitamin.
Correct Answer
C. Vitamin K
Explanation
Warfarin is a blood-thinner that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Vitamin K is essential for the activation of these clotting factors, so when someone is taking warfarin, it is important for them to consistently maintain their intake of vitamin K. This is because sudden changes in vitamin K intake can affect the effectiveness of warfarin, leading to an increased risk of bleeding or blood clots. Therefore, it is crucial for individuals on warfarin to monitor their vitamin K intake and maintain it at a consistent level.
9.
Increasing exposure to sunlight will increase the level of this vitamin within the body.
Correct Answer
B. Vitamin D
Explanation
Exposure to sunlight is known to stimulate the production of vitamin D in the body. When the skin is exposed to UVB rays from the sun, it triggers the synthesis of vitamin D in the skin cells. This vitamin is then converted into its active form in the liver and kidneys. Therefore, increasing exposure to sunlight will increase the level of vitamin D within the body.
10.
Vitamin C is important for the synthesis of this important structural component of blood vessels, tendons, ligaments and bone.
Correct Answer
C. Collagen
Explanation
Collagen is a protein that is essential for the structure and strength of blood vessels, tendons, ligaments, and bones. Vitamin C plays a crucial role in the synthesis of collagen, as it is required for the conversion of proline and lysine into hydroxyproline and hydroxylysine, respectively. Without sufficient vitamin C, collagen synthesis is impaired, leading to weakened blood vessels, tendons, ligaments, and bones. Therefore, collagen is the correct answer in this context.
