1. Which of the following is an example of a macronutrient?

• A. Vitamin C
• B. Iron
• C. Calcium
• D. Fiber

Correct answer: D

Rationale: The correct answer is D: Fiber. Macronutrients are nutrients required by the body in larger amounts, and they include carbohydrates, proteins, and fats. Fiber is a type of carbohydrate that falls under this category. Vitamin C (choice A) is a water-soluble vitamin, Iron (choice B) is a mineral, and Calcium (choice C) is also a mineral, not a macronutrient. Therefore, Fiber is the only macronutrient listed in the choices.

2. What is a common symptom of an upper respiratory infection in children?

• A. Constipation
• B. Excessive vomiting
• C. Nasal congestion
• D. Abdominal pain

Correct answer: C

Rationale: Nasal congestion is a common symptom of an upper respiratory infection in children. It is typically accompanied by cough and sore throat. Constipation (choice A) and excessive vomiting (choice B) are not typical symptoms of upper respiratory infections. Abdominal pain (choice D) is more commonly associated with gastrointestinal issues rather than upper respiratory infections.

3. The motive for a person who alters their diet due to religious convictions is most likely related to their ___.

• A. values
• B. body image
• C. ethnic heritage
• D. functional association

Correct answer: A

Rationale: The correct answer is A, 'values.' When individuals alter their diet due to religious convictions, it is primarily driven by their personal or cultural values associated with their faith. This choice reflects the strong influence that religious beliefs can have on dietary choices. Choice B, 'body image,' is incorrect because altering one's diet for religious reasons is more about spiritual beliefs than physical appearance. Choice C, 'ethnic heritage,' is incorrect as it pertains more to cultural background rather than religious convictions. Choice D, 'functional association,' is incorrect as it does not directly relate to the motivation behind altering one's diet for religious reasons.

4. What is an important dietary consideration for a child with celiac disease?

• A. Increased iron intake
• B. Gluten-free diet
• C. High-protein diet
• D. Low-sodium diet

Correct answer: B

Rationale: A gluten-free diet is crucial for managing celiac disease in children because it helps prevent intestinal damage and alleviate symptoms. Gluten is a protein found in wheat, barley, and rye, and it triggers an immune response in individuals with celiac disease, damaging the lining of the small intestine. Therefore, choices A, C, and D are incorrect. While iron intake is important for overall health, a child with celiac disease can still meet their iron needs through sources that are naturally gluten-free or fortified. A high-protein diet or a low-sodium diet are not specifically required for managing celiac disease.

5. Why is randomization important in a scientific experiment?

• A. To minimize the impact of confounding variables.
• B. To eliminate bias in the assignment of subjects to groups.
• C. To contribute to the accuracy and validity of the experiment's results.
• D. To prevent systematic differences between groups.

Correct answer: B

Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.
