1. Which vitamin is essential for proper blood clotting?
- A. Vitamin A
- B. Vitamin E
- C. Vitamin K
- D. Vitamin C
Correct answer: C
Rationale: Vitamin K is vital for the synthesis of clotting factors, which are necessary for proper blood clotting. Vitamin A (Choice A) is important for vision and skin health, not blood clotting. Vitamin E (Choice B) is an antioxidant that helps protect cells from damage but is not directly involved in blood clotting. Vitamin C (Choice D) is essential for collagen synthesis and a healthy immune system, but it does not play a direct role in blood clotting.
2. A client states they are taking greater than the recommended daily allowance of vitamin E to prevent cataracts. Which complication should the nurse educate the client as related to taking excessive amounts of vitamin E?
- A. Lung cancer
- B. Stroke
- C. Diarrhea
- D. Liver damage
Correct answer: B
Rationale: The correct answer is B: Stroke. High doses of vitamin E supplements have been associated with an increased risk of hemorrhagic stroke due to its blood-thinning properties. Option A, lung cancer, is not a known complication of excessive vitamin E intake. Option C, diarrhea, is more commonly associated with excessive intake of other vitamins or minerals. Option D, liver damage, is not a commonly reported complication of vitamin E overdose.
3. Which biomolecule is responsible for the storage and transfer of genetic information?
- A. Carbohydrates
- B. Proteins
- C. Lipids
- D. Nucleic acids
Correct answer: D
Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
4. Generally, lifestyle-related diseases share common risk factors. Which of the following is NOT one of them?
- A. Physical activity
- B. Smoking
- C. Genetics
- D. Nutrition
Correct answer: C
Rationale: Common risk factors for lifestyle-related diseases typically include aspects of one's lifestyle that can be modified or controlled, such as physical activity, smoking habits, and nutrition. These factors can be changed to prevent or manage lifestyle-related diseases. Genetics, on the other hand, is not a modifiable risk factor, meaning it cannot be changed or controlled. Therefore, it is not considered a common risk factor for lifestyle-related diseases. Understanding the modifiable risk factors for these diseases allows for better prevention and management strategies, and helps reduce the risk of complications.
5. Which food item interferes with the effectiveness of warfarin?
- A. Cauliflower
- B. Zucchini
- C. Green beans
- D. Broccoli
Correct answer: D
Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.
