1. Which of the following is a function of carbohydrates in the body?

• A. They provide insulation and support for organs.
• B. They help regulate body temperature.
• C. They serve as the body's main structural components.
• D. They are the body's primary source of energy.

Correct answer: D

Rationale: The correct answer is D. Carbohydrates are the body's primary source of energy, fueling daily activities and bodily functions. Choice A is incorrect because insulation and organ support are primarily provided by adipose tissue and structural proteins, not carbohydrates. Choice B is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not carbohydrates. Choice C is incorrect because structural components like proteins are responsible for building tissues and organs, not carbohydrates.

2. What dietary recommendation should be made to a child with iron-deficiency anemia?

• A. Increase intake of dairy products
• B. Include high-iron foods like spinach and meat
• C. Decrease protein intake
• D. Avoid all grains

Correct answer: B

Rationale: The correct recommendation for a child with iron-deficiency anemia is to include high-iron foods like spinach, red meat, and beans in their diet. These foods are rich sources of iron and can help address the deficiency. Choice A is incorrect as dairy products do not provide significant iron content. Choice C is incorrect because protein intake does not need to be decreased; in fact, lean meats are good sources of iron. Choice D is also incorrect as whole grains can be a part of a healthy diet and do not need to be avoided in this case.

3. What type of vaccine should a child with a history of severe allergic reactions receive?

• A. Live attenuated vaccines
• B. Inactivated vaccines
• C. Subunit vaccines
• D. Recombinant vaccines

Correct answer: B

Rationale: Children with a history of severe allergic reactions should receive inactivated vaccines because they do not contain live pathogens. Live attenuated vaccines (choice A) contain weakened live pathogens and can potentially trigger an allergic reaction in sensitive individuals. Subunit vaccines (choice C) and recombinant vaccines (choice D) may contain components that could still trigger an allergic response in individuals with a history of severe allergies. Inactivated vaccines are the safest choice for individuals with a history of severe allergic reactions as they do not pose a risk of causing an allergic reaction due to the absence of live pathogens.

4. What does the term 'essential nutrient' refer to?

• A. A nutrient that can be synthesized by the body.
• B. A nutrient that is required for proper body functioning.
• C. A nutrient that must be obtained from the diet because the body cannot produce it.
• D. A nutrient that can be stored in the body for long periods.

Correct answer: C

Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.

5. Which nutrient source yields more than 4 kcalories per gram?

• A. plant fats
• B. plant proteins
• C. animal proteins
• D. plant carbohydrates

Correct answer: A

Rationale: The correct answer is plant fats (Choice A). Fats, including plant fats, provide 9 kcalories per gram, which is more than 4 kcalories. Plant proteins (Choice B) and animal proteins (Choice C) provide 4 kcalories per gram. Plant carbohydrates (Choice D) also provide 4 kcalories per gram. Therefore, Choices B, C, and D are incorrect because they do not yield more than 4 kcalories per gram.
