1. When rickets occurs, how is the alveolar bone affected compared to other bones in the body?

• 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. When rickets occurs, the alveolar bone is affected similar to other bones in the body, with the trabeculae of the alveolar bone also weakening. In addition to damaged alveolar bone caused by vitamin D deficiency, dental changes include delayed dentition and small molars. The other choices are incorrect because both statements provided are accurate based on the effects of rickets on the alveolar bone.

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. 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.

4. Which of the following has the greatest effect on an increase in body weight?

• A. Carbohydrate intake
• B. Protein intake
• C. Fat intake
• D. Total kilocalories

Correct answer: D

Rationale: Total kilocalories have the greatest effect on body weight as they represent the overall energy intake from all macronutrients combined. While the consumption of specific macronutrients like carbohydrates, proteins, and fats can affect weight management, the total calories consumed play the most significant role in determining body weight. Therefore, choices A, B, and C are incorrect as they focus on individual macronutrients rather than the overall energy balance provided by total kilocalories.

5. The small intestine is comprised of the cecum, colon, and rectum. The large intestine includes the duodenum, jejunum, and ileum.

• 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: Both statements are false. The small intestine consists of the duodenum, jejunum, and ileum, while the large intestine includes the cecum, colon, and rectum.
