Select all that apply. To lower LDL levels, you should:
- A. consume minimal amounts of hydrogenated and saturated fats
- B. consume more insoluble fibers than soluble fibers
- C. consume alcohol in moderate levels
- D. engage in regular physical activity
Correct Answer: A
Rationale: To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.

Which nutrient is most important for the prevention of osteoporosis?
- A. Vitamin A
- B. Iron
- C. Calcium
- D. Protein
Correct Answer: C
Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength.

Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.
According to the DASH Eating Plan, Carmen's daily sodium intake should not exceed how many milligrams to ensure the plan's effectiveness?
- A. 1000 milligrams
- B. 2500 milligrams
- C. 3000 milligrams
- D. 1500 milligrams
Correct Answer: D
Rationale: The DASH Eating Plan is designed to lower blood pressure and is most effective when daily sodium intake is limited to 1500 milligrams or less. Therefore, choice D is the correct answer. Choices A (1000 milligrams), B (2500 milligrams), and C (3000 milligrams) are incorrect because they either fall below or exceed the recommended daily sodium intake for the DASH Eating Plan.
What is the desirable resting systolic blood pressure for adults?
- A. <130 mmHg>
- B. <105 mmHg>
- C. <120 mmHg>
- D. <140 mmHg>
Correct Answer: C
Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.
Given that orthodontic patients are frequently adolescents, their nutrition and oral self-care are often subpar. A dental hygienist may successfully motivate these noncompliant patients by emphasizing that optimal nutrition and oral self-care can enhance their appearance. Is this true or false?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct Answer: A
Rationale: Both statements are indeed true. Many adolescents undergoing orthodontic treatment often neglect proper nutrition and oral hygiene, leading to subpar practices in these areas. It's common for them to be less attentive to these aspects due to various factors. A dental hygienist's role includes motivating these patients towards better self-care practices. One effective approach is by emphasizing that good nutrition and oral hygiene can significantly enhance their appearance. This approach is particularly effective for adolescents as they are often highly conscious about their looks. The other choices are incorrect because they suggest that one or both of the statements are false, which is not the case.
Lynn is an older adult who lives alone and has requested advice on how to eat a nutritious diet as cheaply as possible. One useful, practical tip for Lynn might be to _____.
- A. buy just a few pieces of fresh fruit at a time, in different stages of ripeness
- B. choose small boxes of frozen vegetables instead of large bags
- C. purchase pre-sliced or shredded cheese rather than whole pieces
- D. avoid buying certain foods in bulk, such as beans or dried legumes
Correct Answer: A
Rationale: Buying a few pieces of fresh fruit at different stages of ripeness ensures that Lynn will have ripe fruit available over several days, reducing waste and cost. Choice B focuses on frozen vegetables but doesn't address the variety and ripeness factor like Choice A. Choice C is about cheese, which may not be as essential for a nutritious diet compared to fresh fruit. Choice D suggests avoiding certain foods in bulk, which might not be as relevant for maintaining a nutritious diet economically as the strategy in Choice A.
