Nursing Elites

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. What should be the next step in the nursing research process?

• A. Review related literature
• B. Seek permission from the hospital administrator
• C. Identify the research problem
• D. Develop methods for data collection

Correct answer: D

Rationale: The correct answer is 'Develop methods for data collection' (Choice D). In the nursing research process, after the research problem has been identified, the next step would typically be to develop methods for how data will be collected. This is essential to effectively address the research problem. 'Review related literature' (Choice A), while an important step, usually occurs after the research problem has been identified and before methods for data collection are developed. 'Seek permission from the hospital administrator' (Choice B) might be necessary at some point in certain situations, but it is not the immediate next step in the research process. 'Identify the research problem' (Choice C) would typically come before developing methods for data collection. Therefore, according to the typical sequence of steps in the nursing research process, Choice D is correct.

3. What type of debridement involves proteolytic enzymes?

• A. Interventional C. Surgical
• B. Mechanical D. Chemical
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. What instruction should a nurse include when teaching a client who has recently been prescribed a low-sodium diet?

• A. Avoid foods such as smoked meats and frozen dinners.
• B. Select foods with less than 4g of sodium as indicated on food labels.
• C. Use soy sauce for flavoring foods instead of table salt.
• D. Processed and prepared foods are typically low in sodium.

Correct answer: A

Rationale: The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.

5. What is the main function of dietary fiber in managing cholesterol levels?

• A. To reduce absorption of dietary fats
• B. To increase cholesterol synthesis
• C. To enhance protein digestion
• D. To decrease cholesterol absorption

Correct answer: D

Rationale: Dietary fiber helps lower cholesterol levels by binding to bile acids and reducing cholesterol absorption.
