1. What is the function of villi and microvilli in the GI tract?

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

2. Begins carb digestion in the mouth:

Correct answer: B

Rationale: Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth by breaking down starches into simpler sugars.

3. What is tocopherol?

Correct answer: D

Rationale: Tocopherol is another name for Vitamin E, a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Choices A, B, and C are incorrect as tocopherol is specifically related to Vitamin E and not Vitamin B1, B2, or B3.

4. A patient on a low-sodium diet should avoid which of the following foods?

Correct answer: C

Rationale: Canned soup is the correct answer. Canned soups are often high in sodium due to added salt and should be avoided on a low-sodium diet. Fresh fruits (Choice A) are typically low in sodium and a good choice for a low-sodium diet. Unsalted nuts (Choice B) are also low in sodium and can be included in a low-sodium diet. Plain rice (Choice D) is a low-sodium food and can be part of a low-sodium diet.

5. Which food would benefit an anemic patient by increasing their intake?

Correct answer: A

Rationale: An anemic patient would benefit from increasing their intake of beef. Beef is an excellent source of heme iron, which is critical for treating anemia. Heme iron is absorbed more readily by the body compared to non-heme iron found in plant-based foods. Apples and white bread, while healthy, do not contain significant amounts of heme iron. Fish, although it does contain iron, it's non-heme iron, which is not as efficiently absorbed by the body as heme iron, hence less effective in treating anemia.
