1. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

A. pancreatic amylases, small intestine
B. brush border enzymes, small intestine
C. luminal enzymes, large intestine
D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

2. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

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: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

3. A client who follows the dietary laws of Orthodox Judaism is being cared for by a nurse. Which of the following meal choices should the nurse request for the client?

A. Turkey and cheese sandwich
B. Spaghetti with tomato sauce
C. Pork chop and applesauce
D. Scrambled eggs and bacon

Correct answer: B

Rationale: The correct meal choice for a client following the dietary laws of Orthodox Judaism is 'Spaghetti with tomato sauce.' Orthodox Judaism prohibits mixing meat and dairy and consuming pork. The other choices - 'Turkey and cheese sandwich' (mixing meat and dairy), 'Pork chop and applesauce' (contains pork), and 'Scrambled eggs and bacon' (mixing meat and dairy) - do not adhere to the kosher dietary laws.

4. What is a disadvantage of using a food frequency questionnaire?

A. It does not influence the food choices of the consumer
B. It is not affected by seasonal changes in the diet
C. It is not effective for monitoring short-term changes in food intake
D. It does not take too long to obtain the results

Correct answer: C

Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.
