1. Which vitamin deficiency is most likely to cause bleeding disorders?
- A. Vitamin A
- B. Vitamin E
- C. Vitamin K
- D. Vitamin D
Correct answer: C
Rationale: Vitamin K is essential for blood clotting as it plays a crucial role in the activation of clotting factors. Deficiency of Vitamin K can lead to impaired blood clotting, resulting in bleeding disorders. Vitamin A is more associated with vision and skin health, not blood clotting. Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.
2. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?
- A. Strained fruits
- B. Pureed meats
- C. Cooked egg whites
- D. Iron-fortified cereal
Correct answer: Iron-fortified cereal
Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.
3. Compared to the typical American diet, what does the DASH diet provide more of?
- A. More saturated fats
- B. Fewer whole grains
- C. More fruits and vegetables
- D. Fewer dairy products
Correct answer: C
Rationale: The correct answer is C. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, emphasizes the consumption of fruits and vegetables, which are high in potassium, fiber, and antioxidants. These nutrients help lower blood pressure. Therefore, compared to the typical American diet, the DASH diet provides more fruits and vegetables. Choices A, B, and D are incorrect. The DASH diet doesn't focus on providing more saturated fats or fewer whole grains or dairy products. In fact, it encourages the consumption of whole grains and low-fat dairy products to promote a balanced and healthy diet.
4. Saturated fats are generally found in animal products with a few exceptions. Which of the following is a plant product that contains a large proportion of saturated fat?
- A. canola oil
- B. olive oil
- C. soybean oil
- D. coconut oil
Correct answer: D
Rationale: Coconut oil is a plant-based oil that is high in saturated fat, unlike most other plant oils, which are typically unsaturated.
5. Which mineral is essential for wound healing?
- A. iodine
- B. chromium
- C. zinc
- D. sulfate
Correct answer: C
Rationale: Zinc plays a critical role in wound healing due to its involvement in cell proliferation, immune function, and protein synthesis, all of which are essential for tissue repair.
