1. An imbalance of which nutrient may elicit delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: The correct answer is B: Iron. The provided extract mentions that iodine deficiency can cause delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter. Zinc, Sodium, and Potassium are not associated with these specific symptoms. Zinc deficiency can lead to other health issues but not the ones mentioned. Sodium and Potassium imbalances do not typically result in the symptoms described in the question.

2. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?

• A. Cyclamate
• B. Acesulfame-K
• C. Saccharin
• D. Aspartame

Correct answer: D

Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.

3. 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.

4. Which nutrient is most closely associated with the prevention of neural tube defects in a developing fetus for a woman planning to become pregnant?

• A. Calcium
• B. Folate
• C. Vitamin A
• D. Choline

Correct answer: B

Rationale: The correct answer is folate. Folate, also known as Vitamin B9, is vital for the prevention of neural tube defects in the developing fetus. It is primarily responsible for the creation and repair of DNA, which is essential during rapid growth stages such as pregnancy. While nutrients like calcium, vitamin A, and choline are important for pregnancy, they are not as directly linked to preventing neural tube defects as folate. Calcium is crucial for the baby's bone and teeth development. Vitamin A is essential for vision, immune function, and cellular growth. Choline supports brain development and neural functioning. However, none of these nutrients have the same direct impact on preventing neural tube defects as folate.

5. Given that orthodontic patients are frequently adolescents, their nutrition and oral self-care are often subpar. A dental hygienist may successfully motivate these noncompliant patients by emphasizing that optimal nutrition and oral self-care can enhance their appearance. Is this 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: A

Rationale: Both statements are indeed true. Many adolescents undergoing orthodontic treatment often neglect proper nutrition and oral hygiene, leading to subpar practices in these areas. It's common for them to be less attentive to these aspects due to various factors. A dental hygienist's role includes motivating these patients towards better self-care practices. One effective approach is by emphasizing that good nutrition and oral hygiene can significantly enhance their appearance. This approach is particularly effective for adolescents as they are often highly conscious about their looks. The other choices are incorrect because they suggest that one or both of the statements are false, which is not the case.
