Nursing Elites

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 teaching a group of clients who are at risk for heart disease about decreasing saturated fats in their diet. Which of the following fats should the nurse recommend the clients use when cooking?

• A. Palm oil
• B. Peanut oil
• C. Canola oil
• D. Stick margarine

Correct answer: C

Rationale: Canola oil is lower in saturated fats compared to palm oil, peanut oil, and stick margarine, making it a healthier option for clients at risk for heart disease. Palm oil is high in saturated fats, peanut oil has a moderate amount of saturated fats, and stick margarine is also high in saturated fats and trans fats, which are not heart-healthy choices.

3. During which stage of life is it most critical to build bone mass to prevent osteoporosis?

• A. Infancy
• B. Early childhood
• C. Adolescence
• D. Young adulthood

Correct answer: C

Rationale: Adolescence is the most critical stage for building bone mass, which plays a significant role in preventing osteoporosis in later life. During adolescence, approximately 45% of adult bone mass is formed. Although bone mass can be built during infancy, early childhood, and young adulthood, it is not as significant as during adolescence, making choices A, B, and D incorrect. Therefore, focusing on adequate nutrition and physical activity during adolescence is vital for long-term bone health.

4. The nurse is completing a nutritional assessment on a client. Which statement made by the client is most concerning to the nurse?

• A. "I notice when I take a vitamin E supplement, I bruise more easily."
• B. "I work nights and rarely go outside during the day."
• C. "I take warfarin, so I need to limit the amount of green leafy vegetables I eat."
• D. "My vitamin supplement has the recommended daily allowance of vitamin A."

Correct answer: A

Rationale: The correct answer is A. Excessive intake of vitamin E can increase the risk of bleeding as it acts as a blood thinner. Bruising easily may indicate too much vitamin E. Choice B is not as concerning as it describes a lifestyle that may lead to vitamin D deficiency due to lack of sunlight exposure. Choice C shows awareness of the interaction between warfarin and vitamin K, which is expected. Choice D indicates knowledge of the vitamin A content in the supplement, which is not a cause for concern.

5. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
