1. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

2. What differentiates one amino acid from another?

• A. The amine group
• B. The acid group
• C. The side chain
• D. None of the above

Correct answer: C

Rationale: The side chain, also known as the R group, is what differentiates one amino acid from another. It imparts unique properties to each amino acid, thereby influencing their roles and functions in proteins. The amine group (Choice A) and the acid group (Choice B) are components of all amino acids and do not cause the differences among various amino acids. Choice D is incorrect as it suggests that none of the given options account for the differences, which is not true as the side chain does.

3. Which food provides a 1-ounce serving of grains for a preschool child?

• A. 1 cup of ready-to-eat cereal flakes
• B. 1⁄2 slice of whole wheat bread
• C. 1⁄2 of a 6-inch flour tortilla
• D. 1 cup of cooked rice

Correct answer: A

Rationale: The correct answer is A: 1 cup of ready-to-eat cereal flakes. For a preschool child, 1 cup of ready-to-eat cereal flakes provides a 1-ounce serving of grains, meeting the requirement. Choice B, 1⁄2 slice of whole wheat bread, is not the correct answer as it does not constitute a 1-ounce serving of grains. Similarly, choice C, 1⁄2 of a 6-inch flour tortilla, does not offer a 1-ounce serving of grains. Choice D, 1 cup of cooked rice, also does not provide a 1-ounce serving of grains for a preschool child, making it an incorrect choice.

4. A client with a large lower-leg ulcer needs protein for wound healing. Which of the following foods should the nurse suggest?

• A. Kidney beans
• B. Grilled salmon
• C. Peanut butter
• D. Raw spinach

Correct answer: B

Rationale: Grilled salmon is the best choice for providing high-quality protein for wound healing. Salmon is rich in essential amino acids, omega-3 fatty acids, and vitamin D, which can help promote tissue repair and reduce inflammation. Kidney beans, peanut butter, and raw spinach are good protein sources but do not offer the same level of high-quality protein and nutrients needed specifically for wound healing.

5. What are the best food sources of magnesium?

• A. oils, bananas, and pork
• B. pizza, potatoes, and tomatoes
• C. milk, rice, and apples
• D. legumes, whole grains, and chocolate

Correct answer: D

Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.
