Nutrition Final Exam
1. What is the primary role of dietary guidelines?
- A. To ensure that all food groups are consumed in appropriate proportions.
- B. To prevent chronic diseases and promote overall well-being.
- C. To help individuals meet their nutritional needs while reducing the risk of chronic disease.
- D. To offer specific recommendations for the intake of nutrients that support health.
Correct answer: C
Rationale: The correct answer is C: 'To help individuals meet their nutritional needs while reducing the risk of chronic disease.' Dietary guidelines are designed to provide guidance on the types and amounts of food that support good health and reduce the risk of chronic diseases. Choice A has been corrected to mention 'appropriate proportions' instead of 'equal amounts,' as dietary guidelines emphasize balance and variety. Choice B is partially correct, but the primary focus of dietary guidelines is on meeting nutritional needs. Choice D is incorrect because while dietary guidelines may include nutrient recommendations, their primary focus is on overall dietary patterns rather than specific nutrient intake.
2. In what units are energy measurements expressed by most scientists and nutritionists outside the United States?
- A. newtons
- B. liters
- C. kilojoules
- D. kilocalories
Correct answer: C
Rationale: Kilojoules are the standard units of energy used by most scientists and nutritionists worldwide. Newtons are units of force, liters are units of volume, and kilocalories are more commonly used in the United States but not as widely adopted internationally for energy measurements. Therefore, the correct answer is 'kilojoules.'
3. What is the primary treatment for a child with acute otitis media?
- A. Antihistamines
- B. Nasal decongestants
- C. Antibiotics
- D. Ear drops
Correct answer: C
Rationale: The correct answer is C: Antibiotics. Antibiotics are the primary treatment for acute otitis media because the condition is often caused by a bacterial infection. Antihistamines (choice A) and nasal decongestants (choice B) are not the primary treatments for acute otitis media as they do not target the bacterial infection. Ear drops (choice D) are not the primary treatment for acute otitis media; antibiotics are required to treat the underlying bacterial cause.
4. What intervention is recommended for a child with severe dehydration?
- A. Oral rehydration therapy
- B. Intravenous fluid replacement
- C. High-protein diet
- D. Increased physical activity
Correct answer: B
Rationale: Intravenous fluid replacement is the recommended intervention for a child with severe dehydration because it allows for rapid restoration of fluid and electrolyte balance. In severe cases, oral rehydration therapy (Choice A) may not be tolerated due to the child's condition. A high-protein diet (Choice C) is not the primary intervention and does not address the immediate fluid and electrolyte imbalance. Increased physical activity (Choice D) is contraindicated in severe dehydration as it can exacerbate fluid loss, making intravenous fluid replacement the most suitable choice for prompt correction of the severe dehydration.
5. Which nutrient is classified as a micronutrient?
- A. minerals
- B. proteins
- C. alcohols
- D. carbohydrates
Correct answer: A
Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.
