1. 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.

2. Which statement does not describe a potential role of minerals in the body?

• A. they provide calories and energy to the body
• B. they help maintain fluid balance in the body
• C. they give teeth and bone their strength
• D. they help muscles contract

Correct answer: A

Rationale: Minerals do not provide calories or energy; instead, they play various roles such as building strong bones and teeth, maintaining fluid balance, and supporting muscle contractions.

3. Before Dianne performs the formal research study, what do you call the pre-testing, small-scale trial run to determine the effectiveness of data collection and methodological problems that might be encountered?

• A. Sampling
• B. Pre-testing
• C. Pre-Study
• D. Pilot Study

Correct answer: D

Rationale: The correct answer is 'Pilot Study.' A pilot study is a small-scale trial run conducted before the formal research study to identify and address any issues related to data collection and methodology. This helps in determining the effectiveness of the research process and identifying potential problems that may arise. Choice A, 'Sampling,' refers to the process of selecting a subset of individuals from a larger population for research. Choice B, 'Pre-testing,' simply involves testing something before the main testing phase. Choice C, 'Pre-Study,' is not a commonly used term in research methodology and does not specifically refer to the small-scale trial run described in the question.

4. Which organ produces and secretes bicarbonate ions and insulin?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: B

Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.

5. Patients maintained using peritoneal dialysis may gain weight because:

• A. their appetite is increased
• B. physical activity is limited
• C. they absorb glucose from the dialysate
• D. they absorb amino acids from the dialysate

Correct answer: C

Rationale: Glucose from the peritoneal dialysis solution can be absorbed into the bloodstream, leading to weight gain if not balanced with diet and activity.
