Nursing Elites

1. How should the nurse manage a child with acute lymphoblastic leukemia (ALL) who is receiving chemotherapy?

• A. Avoid all physical activity
• B. Ensure strict infection control measures
• C. Increase daily caloric intake
• D. Limit fluid intake

Correct answer: B

Rationale: The correct answer is B: Ensure strict infection control measures. Children with acute lymphoblastic leukemia (ALL) who are undergoing chemotherapy have compromised immune systems, making them highly susceptible to infections. Implementing strict infection control measures, such as hand hygiene, limiting exposure to sick individuals, and maintaining a clean environment, is essential to prevent infections. Choice A is incorrect because avoiding all physical activity may not be necessary as long as the child's activity level is appropriate. Choice C is incorrect because increasing daily caloric intake is important to support the child's nutritional needs during treatment. Choice D is incorrect because limiting fluid intake is not typically recommended unless specifically advised by the healthcare provider.

2. What is one primary factor that influences nutrient needs in individuals?

• A. Age
• B. Gender
• C. Genetics
• D. Physical activity level

Correct answer: A

Rationale: Correct. Age is one of the primary factors influencing nutrient needs. Different life stages, such as infancy, childhood, adulthood, and old age, require varying amounts of nutrients. Gender (choice B) can influence nutrient needs to some extent, but age plays a more significant role. Genetics (choice C) may affect how individuals metabolize certain nutrients but is not a primary factor in determining overall nutrient needs. Physical activity level (choice D) can impact energy requirements but is not as fundamental as age in influencing overall nutrient needs.

3. What is the recommended daily intake of fiber for adults?

• A. 10 grams
• B. 15 grams
• C. 20 grams
• D. 25 grams

Correct answer: D

Rationale: The recommended daily intake of fiber for adults is 25 grams. Fiber plays a crucial role in maintaining digestive health, preventing constipation, and aiding in weight management. Options A (10 grams), B (15 grams), and C (20 grams) are incorrect as they are below the recommended daily intake of fiber for adults, which is 25 grams.

4. What is one characteristic that differentiates vitamins from minerals?

• A. Vitamins are organic compounds.
• B. Vitamins provide energy.
• C. Vitamins are considered micronutrients.
• D. Vitamins are essential in small amounts.

Correct answer: A

Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.

5. Why is peer review important in scientific research?

• A. To expedite publication of results.
• B. To facilitate the replication of studies.
• C. To verify the accuracy and validity of research findings.
• D. To enhance the credibility of the research.

Correct answer: C

Rationale: Peer review is crucial in scientific research to verify the accuracy and validity of research findings. By subjecting research papers to evaluation by experts in the field, peer review ensures that the study's methods, results, and conclusions are robust and reliable. This process helps to maintain high standards of quality in scientific publications, providing credibility to the research. Choices A and D are incorrect because the primary purpose of peer review is not to expedite publication or solely enhance credibility; its core function is to validate the research's accuracy and validity. Choice B, while beneficial, is not the primary reason for peer review; replication is a byproduct of the rigorous evaluation of research methods and findings.
