1. Which risk factors increase the risk of atherosclerosis?

• A. Exercise
• B. Excessive sun exposure
• C. Insufficient vaccinations
• D. Smoking

Correct answer: D

Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.

2. Poor nutrition results in delayed eruption and exfoliation of deciduous teeth and increased dental caries. Increased caries susceptibility in at-risk children may be related to changes in salivary composition caused by malnutrition.

• 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: A

Rationale: Both statements are true. Poor nutrition can affect tooth development and increase the risk of dental caries in children.

3. What factor has been shown to contribute to poor nutritional health among adolescents?

• A. Most teens choose fruit juice and milk over soda
• B. Many teens consume energy drinks on a regular basis
• C. Teens have busy schedules and rarely drink fluids throughout the day
• D. Teens are more likely to consume low-fat milk

Correct answer: B

Rationale: The correct answer is B because many teens regularly consume energy drinks, which can contribute to poor nutritional health due to their high sugar and caffeine content, leading to unhealthy dietary patterns. Choice A is incorrect because choosing fruit juice and milk over soda would generally be considered a healthier choice. Choice C is incorrect as busy schedules leading to inadequate fluid intake might impact hydration but not necessarily poor nutritional health. Choice D is also incorrect as consuming low-fat milk is not typically a significant factor contributing to poor nutritional health among adolescents.

4. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

• A. pancreatic amylases, small intestine
• B. brush border enzymes, small intestine
• C. luminal enzymes, large intestine
• D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

5. A nurse is instructing the mother of a toddler who has iron-deficiency anemia to increase iron in the child's diet in addition to the prescribed iron supplement. Which of the following foods should the nurse recommend?

• A. Skim milk
• B. Bananas
• C. Tuna fish
• D. Cucumbers

Correct answer: C

Rationale: Tuna fish is a good source of iron and would be beneficial for a toddler with iron-deficiency anemia. Skim milk, bananas, and cucumbers are not significant sources of iron and would not help in increasing the iron levels in the child's diet. Skim milk, in particular, can inhibit iron absorption due to its calcium content, which is important for the nurse to educate the mother about.
