Nursing Elites

1. High intakes of which of the following interfere with copper absorption and can lead to a deficiency?

• A. chromium
• B. sodium
• C. zinc
• D. manganese

Correct answer: C

Rationale: The correct answer is C, zinc. High intakes of zinc can interfere with copper absorption, potentially leading to copper deficiency. Copper is essential for various bodily functions, including iron metabolism. Choice A, chromium, is incorrect because chromium does not interfere with copper absorption. Choice B, sodium, and Choice D, manganese, are also incorrect as they do not interfere with copper absorption.

2. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

• A. The DRIs replace the older recommended daily allowances
• B. Current DRIs attempt to estimate required nutrients to improve long-term health
• C. DRIs specifically address individuals whose requirements are affected by a disease state
• D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients

Correct answer: C

Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

3. On the study “effects of effective nurse-patient communication in decreasing anxiety of post operative patients” What is the Dependent variable?

• A. Effective Nurse-patient communication
• B. Communication
• C. Anxiety level
• D. Post operative patient

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. A client with diabetes is being taught by a nurse about the dietary source that should provide the greatest percentage of calories. Which of the following statements indicates the client understands the teaching?

• A. "Most of my calories each day should be from fats."?
• B. "I should eat more calories from complex carbohydrates than anything else."?
• C. "Simple sugars are needed more than other calorie sources."?
• D. "Protein should be my main source of calories."?

Correct answer: B

Rationale: The correct answer is '"I should eat more calories from complex carbohydrates than anything else."?' Clients with diabetes should focus on complex carbohydrates as their primary calorie source because they have a lower impact on blood sugar levels compared to simple sugars or fats. Choice A is incorrect because a high intake of fats can lead to various health issues. Choice C is incorrect because simple sugars can cause rapid spikes in blood sugar levels. Choice D is incorrect as while protein is important, it should not be the main source of calories for someone with diabetes.

5. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.
