1. Which of the following statements is false?
- A. People with a vitamin K deficiency experience increased clotting time
- B. The major function of vitamin E is promoting vision
- C. Vitamin D functions as a hormone
- D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash
Correct answer: B
Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.
2. The RDA for iron is higher in premenopausal women than for men or postmenopausal women because of the blood loss during menstruation.
- A. Both the statement and the reason are correct and related.
- B. Both the statement and the reason are correct but are not related.
- C. The statement is correct, but the reason is not correct.
- D. The statement is not correct, but the reason is correct.
Correct answer: A
Rationale: Both the statement and the reason are correct and related. The Institute of Medicine (IOM) recommends 18 mg of iron per day for women 19 to 50 years old, 8 mg/day for women 51 years old and older, and men 19 years old and older. During menstruation, women lose blood containing iron, leading to a higher iron requirement in premenopausal women compared to men or postmenopausal women. This increased demand aims to replenish the iron lost during this physiological process. Therefore, the statement and reason are directly linked, explaining why the RDA for iron is higher in premenopausal women than in men or postmenopausal women. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.
3. The nurse is educating a client about foods high in antioxidants A and C. Which breakfast items chosen by the client would indicate that the education was sufficient?
- A. Fried eggs, sausage, and whole wheat toast
- B. Oatmeal with blueberries and coffee
- C. Cereal with strawberries and low-fat milk
- D. Hard-boiled eggs, cantaloupe, and orange juice
Correct answer: D
Rationale: Hard-boiled eggs, cantaloupe, and orange juice are high in antioxidants A and C.
4. Each statement is true of water-soluble vitamins, except one. Which is it?
- A. Act as coenzymes
- B. Deficiencies develop rapidly
- C. Daily intake is necessary
- D. Absorbed in the jejunum
Correct answer: B
Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.
5. When counseling a teenager about fast food, a dental hygienist could correctly cite which of the following facts, with one exception. Which is the exception?
- A. Most fast food menus lack a rich source of vitamin A
- B. Consumer demands have driven the establishment of salads and other healthy menu items
- C. Shortages of biotin, folate, pantothenic acid, and copper are reported in fast foods
- D. Studies reveal that protein is lacking in most menu items
Correct answer: D
Rationale: The correct answer is 'D'. Fast food is generally not deficient in protein since it often contains meat, a significant source of protein. On the other hand, fast food is known to lack essential nutrients like Vitamin A and certain minerals, as mentioned in choices 'A' and 'C'. Choice 'B' is also accurate as many fast food establishments have started offering healthier options such as salads due to customer demands. Therefore, all options are true except 'D', which makes it the exception.
