1. Select all that apply. Which of the following are true about protein digestion?

• A. the end products of protein digestion are amino acids
• B. protein/polypeptides are digested in the large intestine by trypsin
• C. A, D
• D. protein/polypeptides are digested in the stomach by pepsin

Correct answer: C

Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.

2. Where is Vitamin E commonly found?

• A. produced by bacteria in the GI tract
• B. synthesized by the body through sunlight exposure
• C. associated with beriberi deficiency
• D. present in vegetable oils

Correct answer: D

Rationale: Vitamin E is an antioxidant commonly found in sources like vegetable oils, nuts, seeds, and green leafy vegetables. It plays a crucial role in protecting cells from damage. Choices A and B are incorrect as Vitamin E is not produced by bacteria in the GI tract nor synthesized by sunlight exposure. Choice C is incorrect as beriberi is a deficiency of Vitamin B1 (thiamine), not Vitamin E.

3. A person who consumes mostly pre-packaged meals is likely consuming too much ____.

• A. iron
• B. zinc
• C. sodium
• D. riboflavin

Correct answer: C

Rationale: Pre-packaged meals often contain high levels of sodium, which can contribute to hypertension and other health issues when consumed in excess.

4. A vegan patient might be at risk for deficiency in which of the following nutrients?

• A. Vitamin B12
• B. Vitamin C
• C. Carbohydrates
• D. Fiber

Correct answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.

5. A client has a small-bore jejunostomy and is receiving a continuous tube feeding with a high-viscosity formula. Which of the following actions should the nurse take to prevent the tubing from clogging?

• A. Replace the bag and tubing every 24 hours
• B. Flush the tubing with 10 mL water every 6 hours
• C. Administer the feeding by gravity drip
• D. Heat the formula prior to infusion

Correct answer: B

Rationale: To prevent clogging when using high-viscosity formulas in a small-bore jejunostomy, the nurse should flush the tubing with 10 mL of water every 6 hours. This action helps maintain tube patency and prevent blockages. Replacing the bag and tubing every 24 hours (Choice A) is unnecessary and does not specifically address preventing clogging. Administering the feeding by gravity drip (Choice C) or heating the formula prior to infusion (Choice D) are not effective interventions for preventing tubing clogging.
