1. This study, which is an in-depth study of one boy, is a:

• A. case study
• B. longitudinal study
• C. cross-sectional study
• D. evaluative study

Correct answer: A

Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.

2. Which consumption pattern of fermentable carbohydrate is considered most cariogenic?

• A. A single exposure to a large quantity
• B. A single exposure to a small quantity
• C. Multiple exposures of small quantities
• D. Multiple exposures followed by chewing sugarless gum

Correct answer: C

Rationale: Multiple exposures of small quantities are considered most cariogenic. The total amount of dietary fermentable carbohydrate seems to matter less than the form and frequency in which it is consumed. Having multiple exposures of even small quantities of fermentable carbohydrate throughout the day promotes a highly cariogenic environment in the mouth. Choices A and B, involving single exposures, are less cariogenic as they do not sustain the fermentation process over time. Choice D suggests a beneficial practice by chewing sugarless gum after exposures, which can reduce the risk, making it less cariogenic compared to multiple exposures of small quantities.

3. In the following ingredient list, which is the most abundant by weight? Ingredients: enriched flour, sugars, eggs, soy lecithin, artificial colors, natural flavors, milk.

• A. milk
• B. eggs
• C. sugar
• D. enriched flour

Correct answer: D

Rationale: The correct answer is 'enriched flour.' In ingredient lists, items are typically listed by weight in descending order. Therefore, the first ingredient, in this case, 'enriched flour,' is the most abundant by weight. Choice A, 'milk,' is not the most abundant as it appears last in the list. Choice B, 'eggs,' and choice C, 'sugar,' also rank lower in the list compared to 'enriched flour,' making them less abundant by weight.

4. Which is most likely to initiate periodontal disease?

• A. Nutrient deficiencies
• B. Nutrient excesses
• C. Nutrient imbalances
• D. Plaque biofilm

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.

5. For a patient on a ketogenic diet, which macronutrient is primarily increased?

• A. Carbohydrates
• B. Protein
• C. Fats
• D. Fiber

Correct answer: C

Rationale: The correct answer is C: Fats. A ketogenic diet is characterized by high fat intake, moderate protein intake, and very low carbohydrate intake. This diet aims to shift the body's metabolism to use fat as the primary source of energy instead of carbohydrates. Increasing fat intake while reducing carbohydrates is essential for achieving and maintaining a state of ketosis. Therefore, choices A, B, and D are incorrect as they do not align with the macronutrient adjustments required for a ketogenic diet.
