1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. How many amino acids are essential?

• A. 5
• B. 7
• C. 9
• D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

3. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?

• A. Cyclamate
• B. Acesulfame-K
• C. Saccharin
• D. Aspartame

Correct answer: D

Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.

4. Which foods increase iron absorption when consumed with nonheme iron? (SATA)

• A. Kiwi
• B. Strawberries
• C. Coffee
• D. A, B

Correct answer: D

Rationale: Kiwi and strawberries are high in vitamin C, which increases iron absorption.

5. A client has acute dysphagia. Which of the following nursing interventions should be included in the plan of care?

• A. Providing a straw for consumption of liquids
• B. Encouraging larger bites
• C. Placing the client in semi-Fowler's position during meals
• D. Instructing the client to tilt head forward when swallowing

Correct answer: C

Rationale: Placing the client in semi-Fowler's position during meals is the correct intervention for a client with acute dysphagia. This position helps prevent aspiration by facilitating swallowing. Providing a straw for consumption of liquids (Choice A) can increase the risk of aspiration and is not recommended for clients with dysphagia. Encouraging larger bites (Choice B) can also increase the risk of choking and aspiration. Instructing the client to tilt the head forward when swallowing (Choice D) is not the recommended technique for managing dysphagia as it does not address the underlying issue effectively.
