Nutrition Final Exam Quizlet
1. Before publication in a reputable journal, the findings of a research study must undergo scrutiny by experts in the field in a process known as what?
- A. peer review
- B. cohort review
- C. research intervention
- D. double-blind examination
Correct answer: A
Rationale: The correct answer is A: peer review. Before publication, research findings must undergo peer review, where experts in the field evaluate the validity and significance of the study. Choice B, cohort review, is incorrect as it does not involve the same level of evaluation by experts. Choice C, research intervention, is not a term used to describe the evaluation process before publication. Choice D, double-blind examination, refers to a study design where neither the participants nor the researchers know who is receiving a particular treatment, which is not the same as the peer review process.
2. Food energy is commonly expressed in kilocalories and in what other unit?
- A. kilojoules
- B. kilograms
- C. kilometers
- D. kilonewtons
Correct answer: A
Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.
3. What is the primary treatment for a child with an anaphylactic reaction?
- A. Oral antihistamines
- B. Intravenous fluids
- C. Epinephrine injection
- D. Antipyretics
Correct answer: C
Rationale: The correct answer is C: Epinephrine injection. An epinephrine injection is the primary treatment for an anaphylactic reaction in children. Epinephrine acts quickly to reverse severe symptoms such as difficulty breathing, low blood pressure, and hives. Oral antihistamines, although useful for milder allergic reactions, are not sufficient to manage the potentially life-threatening symptoms of anaphylaxis. Intravenous fluids may be necessary to support blood pressure in a child with anaphylaxis but are not the primary treatment. Antipyretics, on the other hand, are medications used to reduce fever and are not indicated as the primary treatment for an anaphylactic reaction.
4. What is the study of how a person's genes interact with nutrients?
- A. genetic counseling
- B. nutritional genomics
- C. genetic metabolomics
- D. nutritional genetics
Correct answer: B
Rationale: Nutritional genomics, the correct answer, specifically focuses on how a person's genes interact with nutrients, affecting health and disease. Genetic counseling (choice A) refers to the process of helping people understand and adapt to the medical, psychological, and familial implications of genetic contributions to disease. Genetic metabolomics (choice C) combines genetic and metabolomic data to study metabolic pathways. Nutritional genetics (choice D) generally refers to the broader field of genetics as it relates to nutrition, while nutritional genomics, the most precise term, delves into the specific gene-nutrient interactions.
5. What is the main function of proteins in the body?
- A. They provide structural components for the body.
- B. They assist in the absorption of vitamins.
- C. They help with the transport of nutrients in the blood.
- D. They help maintain fluid balance in the body.
Correct answer: A
Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).
