Which adolescent student lunch, evaluated by the school nurse, is the least nutritious?

Correct Answer: B

Rationale: The correct answer is B: Hamburger, fries, and soft drink. This meal is considered the least nutritious among the options provided due to its high content of unhealthy fats, processed carbohydrates, and added sugars, which lack essential nutrients. On the other hand, choice A: Ham sandwich, apple, and milk, offers a balanced meal with protein, fiber, vitamins, and calcium. Choice C: Macaroni and cheese, green beans, and peaches, provides a mixture of carbohydrates, vegetables, and fruits. Choice D: Meatloaf, broccoli, and pear slices, includes protein, fiber, and vitamins. Thus, all choices except B provide a more balanced and nutritious meal.

Correct Answer: D

Rationale: The correct answer is D: Hard-boiled eggs, cantaloupe, and orange juice. Cantaloupe and orange juice are rich in vitamins A and C, which are known for their antioxidant properties. Choice A is incorrect because fried eggs, sausage, and whole wheat toast do not contain high levels of antioxidants A and C. Choice B is incorrect because, while blueberries are high in antioxidants, coffee does not provide significant amounts of vitamins A and C. Choice C is incorrect because, although strawberries are a good source of vitamin C, low-fat milk does not contribute significantly to vitamins A and C.

Correct Answer: D

Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.

Correct Answer: B

Rationale: The highest source of calcium among the given choices is the 3 oz of canned salmon. This is due to the presence of bones in canned salmon, which are rich in calcium. The other options, including 1 cup of carrot strips, 1 plain baked potato, and 1 cup of chopped chicken breast, do not contain as much calcium due to the nature of their composition and lack of bone content.

Correct Answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.
