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. You notice that Miss Kate, a bread vendor, receives and changes money, then holds the bread without washing her hands. As a nurse, what should you say to Miss Kate?

A. Miss, don't touch the bread, I'll be the one to pick it up.
B. Miss, please wash your hands before you pick up the bread.
C. Miss, use a pick-up forceps when picking up the bread.
D. Miss, your hands are dirty, I guess I'll try another bread shop.

Correct answer: B

Rationale: The correct answer is B, as it emphasizes the importance of hygiene in food handling, which is crucial to prevent the spread of germs and diseases. The other options do not address the root of the issue, which is the unhygienic handling of food. Option A avoids direct confrontation but does not educate the vendor on proper hygiene. Option C, although it suggests a hygienic method, may not be practical or available in all situations. Option D is an avoidance strategy rather than a way to address the problem.

3. If a person could not make bile, what would happen?

A. experience fatigue, as the body would not be able to make lipid carriers to deliver fat to body cells for energy
B. have less cholesterol being made by the liver
C. need to consume higher levels of fat
D. be unable to absorb most lipids, and fat would be excreted in the feces

Correct answer: D

Rationale: The correct answer is D. Bile is essential for emulsifying fats in the small intestine, allowing them to be absorbed. Without bile, most fats would not be absorbed and would be excreted in the feces. Choices A, B, and C are incorrect because the primary role of bile is in the digestion and absorption of fats, rather than affecting lipid carriers, cholesterol production, or dietary fat consumption.

4. Which of the following statements are true about iron?

A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
B. It is one of the most common nutrient deficiencies in the world.
C. Its absorption is increased by Vitamin C and during pregnancy.
D. Its absorption is increased by tannic acid and calcium in milk.

Correct answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.
