1. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

2. Weight loss therapies that rely on juicing typically provide increased fiber, vitamins, and minerals. As an added incentive, juices contain a lower concentration of sugar than the whole fruit. Are these statements 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: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

3. Which term is used to describe medical practices that have been thoroughly evaluated using scientific methods?

• A. Meta-analysis
• B. Systematic reviews
• C. Evidence-based
• D. Observational studies

Correct answer: C

Rationale: The correct answer is C, 'Evidence-based.' Evidence-based practices refer to medical practices that have been thoroughly evaluated and supported by scientific research. Meta-analysis (A) involves statistical analysis that combines the results of multiple studies. Systematic reviews (B) are comprehensive reviews that synthesize evidence from multiple studies. Observational studies (D) are research methods where researchers observe subjects in their natural environment.

4. When counseling a teenager about fast food, a dental hygienist could correctly cite which of the following facts, with one exception. Which is the exception?

• A. Most fast food menus lack a rich source of vitamin A
• B. Consumer demands have driven the establishment of salads and other healthy menu items
• C. Shortages of biotin, folate, pantothenic acid, and copper are reported in fast foods
• D. Studies reveal that protein is lacking in most menu items

Correct answer: D

Rationale: The correct answer is 'D'. Fast food is generally not deficient in protein since it often contains meat, a significant source of protein. On the other hand, fast food is known to lack essential nutrients like Vitamin A and certain minerals, as mentioned in choices 'A' and 'C'. Choice 'B' is also accurate as many fast food establishments have started offering healthier options such as salads due to customer demands. Therefore, all options are true except 'D', which makes it the exception.
