1. What factor has been shown to contribute to poor nutritional health among adolescents?

• A. Most teens choose fruit juice and milk over soda
• B. Many teens consume energy drinks on a regular basis
• C. Teens have busy schedules and rarely drink fluids throughout the day
• D. Teens are more likely to consume low-fat milk

Correct answer: B

Rationale: The correct answer is B because many teens regularly consume energy drinks, which can contribute to poor nutritional health due to their high sugar and caffeine content, leading to unhealthy dietary patterns. Choice A is incorrect because choosing fruit juice and milk over soda would generally be considered a healthier choice. Choice C is incorrect as busy schedules leading to inadequate fluid intake might impact hydration but not necessarily poor nutritional health. Choice D is also incorrect as consuming low-fat milk is not typically a significant factor contributing to poor nutritional health among adolescents.

2. Which mineral is important for the synthesis of thyroid hormones?

• A. Iron
• B. Zinc
• C. Iodine
• D. Magnesium

Correct answer: C

Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.

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. Proteolytic enzymes are most likely to break down which food type?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.

5. Men generally have a higher RDA than women, except during pregnancy and lactation when women’s nutritional needs increase significantly.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is TRUE. Men typically require a higher Recommended Dietary Allowance (RDA) than women due to physiological differences. However, during pregnancy and lactation, women's nutritional needs increase significantly to support the growth and development of the baby. Therefore, during these stages, women may require a higher RDA compared to men. This exception is crucial to consider when evaluating nutritional requirements based on gender.
