1. 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.

2. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

3. A nurse is developing an education program for a community group about dietary intake of vitamins and minerals in the diet. The nurse should include which of the following foods as sources of vitamin C? (Select the food that does not apply.)

• A. Green pepper
• B. Orange
• C. Cabbage
• D. Milk

Correct answer: D

Rationale: The correct answer is E: Milk. Milk is not a significant source of vitamin C. Choices A, B, C, and D are all good sources of vitamin C. Green pepper, orange, cabbage, and strawberries contain vitamin C and can be included in the diet to meet the body's need for this essential vitamin. Milk, on the other hand, is not known for its vitamin C content, so it does not apply as a source of this particular vitamin.

4. Bones continuously lose and gain minerals. This ongoing process is called?

• A. reorganization
• B. reorienting
• C. demineralizing
• D. remodeling

Correct answer: D

Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.

5. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.
