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. A nurse is providing teaching about formula feeding to the parents of an infant. Which of the following instructions should the nurse include?

• A. Formula that remains in the bottle should not be used for one more feeding.
• B. Formula should be changed to whole milk when the infant is 12 months old.
• C. If the infant is gaining weight too rapidly, do not dilute the formula.
• D. If the infant turns away after taking most of the feeding, stop the feeding.

Correct answer: D

Rationale: If the infant turns away after taking most of the feeding, it indicates they are full, and continuing to feed may lead to overfeeding. Choice A is incorrect because it is not safe to use formula that remains in the bottle for another feeding due to the risk of bacterial contamination. Choice B is incorrect as whole milk should be introduced after the infant is 12 months old, not 9 months old. Choice C is incorrect as diluting formula can compromise the infant's nutrition and should not be done without healthcare provider guidance.

3. Medications that reduce stomach acidity can impair the absorption of _____.

• A. calcium
• B. iron
• C. vitamin D
• D. vitamin C

Correct answer: B

Rationale: Reduced stomach acidity impairs the absorption of iron, as an acidic environment is necessary for optimal iron absorption in the stomach. Choices A, C, and D are incorrect as medications that reduce stomach acidity typically do not significantly affect the absorption of calcium, vitamin D, or vitamin C.

4. A client who is postpartum and has been diagnosed with iron deficiency anemia should be taught to consume which of the following dietary recommendations?

• A. Yogurt and mozzarella
• B. Spinach and beef
• C. Milk and turkey slices
• D. Fish and cottage cheese

Correct answer: C

Rationale: The correct answer is spinach and beef. Both spinach and beef are high in iron, making them excellent choices to help combat iron deficiency anemia. Yogurt, mozzarella, milk, turkey slices, fish, and cottage cheese are not as rich in iron compared to spinach and beef, so they are not the most suitable dietary recommendations for a client with iron deficiency anemia.

5. Where does carbohydrate digestion begin?

• A. Mouth
• B. Esophagus
• C. Stomach
• D. Small intestine

Correct answer: A

Rationale: Carbohydrate digestion begins in the mouth. The enzyme amylase, found in saliva, starts the process by breaking down starches into sugars. The esophagus is a passageway for food to reach the stomach and does not participate in digestion. The stomach mainly digests proteins and is not the primary site for carbohydrate breakdown. While the small intestine does play a crucial role in digesting carbohydrates, it is not where the process initiates. Therefore, the correct answer is the mouth.
