Nutrition Final Exam
1. What is a common side effect of the antibiotic tetracycline in children?
- A. Discoloration of teeth
- B. Increased appetite
- C. Elevated blood glucose levels
- D. Decreased bone density
Correct answer: A
Rationale: Discoloration of teeth is a well-known side effect of tetracycline, especially when administered to children below 8 years of age. Tetracycline can bind to calcium ions in developing teeth, causing them to become discolored and appear yellow or brown. Increased appetite, elevated blood glucose levels, and decreased bone density are not commonly associated with the use of tetracycline in children, making them incorrect choices.
2. 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.
3. An essential nutrient is one that ___
- A. must be made in large quantities by the body
- B. can only be synthesized by the body
- C. cannot be made in sufficient quantities by the body
- D. is used to synthesize other compounds in the body
Correct answer: C
Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.
4. What is the primary reason influencing most people's food choices?
- A. cost
- B. taste
- C. convenience
- D. nutritional value
Correct answer: B
Rationale: The primary reason most people choose the foods they eat is taste. While cost, convenience, and nutritional value also play a role in food choices, taste often takes precedence as people are more likely to select foods that they find appealing in flavor. Therefore, options A, C, and D are incorrect as taste is the chief factor influencing food choices.
5. What is an important aspect of care for a child with congenital heart disease?
- A. Restricting physical activity
- B. Increasing fluid intake
- C. Administering high doses of vitamins
- D. Monitoring growth and development
Correct answer: D
Rationale: Monitoring growth and development is crucial for children with congenital heart disease to ensure they are meeting developmental milestones and managing the disease effectively. This helps healthcare providers assess the child's overall health, detect any potential issues early, and adjust treatment plans accordingly. Restricting physical activity may not be necessary for all children with congenital heart disease and should be determined by their healthcare team based on individual needs. Increasing fluid intake and administering high doses of vitamins may not be directly related to managing congenital heart disease and should be guided by specific recommendations from healthcare providers.
