1. Non-nutrient substances found in plant foods that may demonstrate biological activity in the body are commonly known as ___

• A. Bioenhancements
• B. Inorganic fibers
• C. Phytochemicals
• D. Phytoactive chemicals

Correct answer: C

Rationale: Phytochemicals are bioactive compounds found in plant foods that may affect health. They are known for their potential health benefits, such as antioxidant and anti-inflammatory properties. Choices A, B, and D are incorrect. 'Bioenhancements' is not a term used to describe non-nutrient substances in plant foods. 'Inorganic fibers' do not refer to bioactive compounds found in plants. 'Phytoactive chemicals' is not a commonly used term in nutrition science to describe these compounds.

2. What is a common sign of developmental dysplasia of the hip (DDH) in infants?

• A. Dislocated patella
• B. Limited abduction of the hip
• C. Swelling of the knee
• D. Hyperextension of the leg

Correct answer: B

Rationale: Limited abduction of the hip is a common sign of developmental dysplasia of the hip in infants. It indicates possible hip dislocation or instability, making it a key clinical manifestation to assess for DDH. Dislocated patella (Choice A) is not typically associated with DDH. Swelling of the knee (Choice C) and hyperextension of the leg (Choice D) are not specific signs linked to DDH in infants, further supporting why they are incorrect choices.

3. An essential nutrient is one that ___

• A. must be made in large quantities by the body
• B. can only be synthesized by the body
• C. cannot be made in sufficient quantities by the body
• D. is used to synthesize other compounds in the body

Correct answer: C

Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.

4. What is the main function of proteins in the body?

• A. They provide structural components for the body.
• B. They assist in the absorption of vitamins.
• C. They help with the transport of nutrients in the blood.
• D. They help maintain fluid balance in the body.

Correct answer: A

Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).

5. Gram for gram, which class of nutrient provides the most energy?

• A. fats
• B. alcohols
• C. proteins
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is fats. Fats provide 9 kilocalories per gram, which is more energy-dense compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 kilocalories per gram, fats provide more than twice the energy, making them the most energy-providing nutrient. Alcohols are not considered essential nutrients and do not provide energy for the body, unlike fats, proteins, and carbohydrates. Therefore, fats are the correct answer for the most energy-providing nutrient.
