1. Can bacterial plaque metabolize sucrose, lactose, and fructose? Is fructose, also known as levulose and found naturally in honey, less cariogenic than sucrose and lactose?

A. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
B. No, bacterial plaque cannot metabolize these sugars, and fructose is not less cariogenic.
C. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
D. No, bacterial plaque cannot metabolize these sugars, but yes, fructose is less cariogenic.

Correct answer: A

Rationale: The first statement is correct as bacterial plaque can indeed metabolize sucrose, lactose, and fructose. However, the second statement is inaccurate. Fructose, despite being found naturally in honey and known also as levulose, is not less cariogenic than either sucrose or lactose. This means that its consumption does not result in fewer cavities or tooth decay. Therefore, the correct answer is that bacterial plaque can metabolize these sugars, but fructose is not less cariogenic. Choices B, C, and D are incorrect because they either wrongly assert that bacterial plaque cannot metabolize these sugars or wrongly claim that fructose is less cariogenic.

2. In approximately what percentage of cases is the prevalence seen?

A. Type 1 Diabetes
B. Type 2 Diabetes
C. N/A
D. N/A

Correct answer: A

Rationale: The correct answer is A, Type 1 Diabetes. The prevalence of Type 1 Diabetes is seen in approximately 5% to 10% of cases. This statement highlights a key epidemiological characteristic of Type 1 Diabetes. Choice B, Type 2 Diabetes, is incorrect because the prevalence mentioned does not align with Type 2 Diabetes, which has a much higher prevalence in the general population. Choices C and D are not relevant to the question and can be disregarded.

3. What is the best snack choice for a preschool-age child?

A. Fruit snacks
B. Mini wheat bagel with peanut butter
C. White toast with jelly
D. Sports drink

Correct answer: B

Rationale: The best snack choice for a preschool-age child is a mini wheat bagel with peanut butter as it provides a good balance of carbohydrates, protein, and healthy fats. Fruit snacks, although they contain some fruit flavor, are often high in added sugars and lack essential nutrients. White toast with jelly may provide quick energy but lacks protein and healthy fats, which are important for a balanced snack choice. Sports drinks are typically high in sugar and unnecessary for a preschool-age child's snack, as they are designed for rehydration during intense physical activity, not as a regular snack option.

4. Each statement is true, except one. Which is the exception?

A. Infant formulas should be discontinued at approximately 1 year of age
B. Low-fat milk is not recommended for children younger than 2 years
C. Special toddler formulas are available but are unnecessary
D. Vitamin D-fortified whole milk should not be provided until 2 years

Correct answer: D

Rationale: The correct answer is D. Vitamin D-fortified whole milk should be provided starting at age 1 after discontinuing breast feeding or infant formulas, not at 2 years. Providing whole milk at age 2 is appropriate. Choices A, B, and C are correct statements: infant formulas are typically discontinued around 1 year of age, low-fat milk is not recommended for children under 2 years, and special toddler formulas are unnecessary.
