1. Can bacterial plaque metabolize sucrose, lactose, and fructose? Is fructose, also known as levulose and found naturally in honey, less cariogenic than sucrose and lactose?

• A. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• B. No, bacterial plaque cannot metabolize these sugars, and fructose is not less cariogenic.
• C. Yes, bacterial plaque can metabolize these sugars, but no, fructose is not less cariogenic.
• D. No, bacterial plaque cannot metabolize these sugars, but yes, fructose is less cariogenic.

Correct answer: A

Rationale: The first statement is correct as bacterial plaque can indeed metabolize sucrose, lactose, and fructose. However, the second statement is inaccurate. Fructose, despite being found naturally in honey and known also as levulose, is not less cariogenic than either sucrose or lactose. This means that its consumption does not result in fewer cavities or tooth decay. Therefore, the correct answer is that bacterial plaque can metabolize these sugars, but fructose is not less cariogenic. Choices B, C, and D are incorrect because they either wrongly assert that bacterial plaque cannot metabolize these sugars or wrongly claim that fructose is less cariogenic.

2. What is the major diet-derived antioxidant found in cell membranes?

• A. B12
• B. beta-carotene
• C. vitamin E
• D. vitamin A

Correct answer: C

Rationale: The correct answer is vitamin E. Vitamin E is the major antioxidant found in cell membranes, where it plays a crucial role in protecting them from oxidative damage. Although B12, beta-carotene, and vitamin A are important nutrients with specific functions in the body, they are not the primary antioxidants found in cell membranes. Vitamin E specifically localizes in cell membranes to neutralize free radicals and prevent lipid peroxidation, making it an essential antioxidant for cellular health.

3. A client is being educated by a nurse on snacks suitable for a low-fat, low-sodium, and low-cholesterol diet. Which of the following food choices by the client indicates the need for further teaching?

• A. A slice of cheese
• B. A jam sandwich
• C. A cup of plain popcorn
• D. A small container of applesauce

Correct answer: A

Rationale: The correct answer is A: A slice of cheese. Cheese is high in fat, sodium, and cholesterol, making it unsuitable for a low-fat, low-sodium, and low-cholesterol diet. Choices B, C, and D are more appropriate for such a diet. B: A jam sandwich can be low in fat, sodium, and cholesterol if made with whole grain bread and a low-sugar jam. C: A cup of plain popcorn is a good choice as it is low in fat and can be made without added salt. D: A small container of applesauce is also a suitable option for a low-fat, low-sodium, and low-cholesterol diet.

4. A nurse is providing preventative information to a group of parents with toddlers about choking. Which food item should the nurse recommend for this age group?

• A. Banana slices
• B. Popcorn
• C. Hot dogs
• D. Carrot sticks

Correct answer: A

Rationale: Banana slices are the most suitable food option for toddlers to prevent choking. Toddlers are at a higher risk of choking due to their small airways and developing chewing abilities. Banana slices are soft, easy to chew, and less likely to cause choking compared to other options. Popcorn and hot dogs are common choking hazards for young children due to their shape and texture. While carrot sticks may be a healthy choice, they can also pose a choking risk due to their hardness and shape. Therefore, recommending banana slices to parents of toddlers is the safest choice to prevent choking incidents, making choice 'A' the correct answer. Choices 'B', 'C', and 'D' are incorrect because they can potentially cause choking in toddlers.

5. Where is Vitamin K synthesized?

• A. by bacteria in the GI tract
• B. by the body by sunlight
• C. deficiency is called beriberi
• D. found in vegetable oils

Correct answer: A

Rationale: Vitamin K is synthesized by bacteria in the gastrointestinal tract. Choice B is incorrect as the synthesis of Vitamin D, not K, can be induced by sunlight exposure. Choice C is incorrect as beriberi is a condition caused by thiamine (Vitamin B1) deficiency, not Vitamin K. Choice D is incorrect as Vitamin E is commonly found in vegetable oils, not Vitamin K.
