1. Which of the following statements are true about iron?

• A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
• B. It is one of the most common nutrient deficiencies in the world.
• C. Its absorption is increased by Vitamin C and during pregnancy.
• D. Its absorption is increased by tannic acid and calcium in milk.

Correct answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.

2. Which nutrient is most important for the prevention of osteoporosis?

• A. Vitamin A
• B. Iron
• C. Calcium
• D. Protein

Correct answer: C

Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength. Vitamin A is important for vision and immune function but is not directly related to bone health. Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.

3. Which adolescent student lunch, evaluated by the school nurse, is the least nutritious?

• A. Ham sandwich, apple, and milk
• B. Hamburger, fries, and soft drink
• C. Macaroni and cheese, green beans, and peaches
• D. Meatloaf, broccoli, and pear slices

Correct answer: B

Rationale: The correct answer is B: Hamburger, fries, and soft drink. This meal is considered the least nutritious among the options provided due to its high content of unhealthy fats, processed carbohydrates, and added sugars, which lack essential nutrients. On the other hand, choice A: Ham sandwich, apple, and milk, offers a balanced meal with protein, fiber, vitamins, and calcium. Choice C: Macaroni and cheese, green beans, and peaches, provides a mixture of carbohydrates, vegetables, and fruits. Choice D: Meatloaf, broccoli, and pear slices, includes protein, fiber, and vitamins. Thus, all choices except B provide a more balanced and nutritious meal.

4. Weight loss therapies that rely on juicing typically provide increased fiber, vitamins, and minerals. As an added incentive, juices contain a lower concentration of sugar than the whole fruit. Are these statements true or false?

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

5. Dental hygienists should not encourage patients with eating disorders such as bulimia to brush immediately after vomiting because self-induced vomiting causes erosion of tooth enamel and dentin hypersensitivity.

• 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: D

Rationale: The corrected question emphasizes that patients with eating disorders like bulimia should not brush immediately after vomiting as it can worsen enamel erosion due to the acidic content in the mouth. The correct answer is D because patients should rinse with water or a fluoride mouthwash instead of brushing to protect their teeth. Choice A is incorrect because encouraging patients to brush after vomiting is not recommended. Choice B is incorrect as the reason provided is valid but not suitable for the action of encouraging brushing. Choice C is incorrect as the reason for not brushing after vomiting is to prevent enamel erosion.
