Nutrition Final Exam
1. What is one function of water in the human body?
- A. Water provides calories for energy.
- B. Water helps transport nutrients and waste products.
- C. Water acts as a solvent for many biological reactions.
- D. Water maintains body temperature.
Correct answer: B
Rationale: The correct answer is B: Water helps transport nutrients and waste products. Water plays a crucial role in the body by aiding in the transportation of essential nutrients to cells and removing waste products. While water is essential for various metabolic processes, it does not provide calories for energy (choice A). Although water can act as a solvent for biological reactions (choice C), its primary function is not as a solvent. Additionally, while water does help in regulating body temperature to some extent, its main role is not to maintain body temperature (choice D).
2. What is a common sign of dehydration in a child with diarrhea?
- A. Decreased urine output
- B. Increased appetite
- C. Warm, dry skin
- D. Elevated blood pressure
Correct answer: A
Rationale: The correct answer is A: Decreased urine output. When a child with diarrhea is dehydrated, they may have decreased urine output, indicating that their body is conserving fluids. This sign highlights the importance of fluid replacement to prevent worsening dehydration. Choices B, C, and D are incorrect. Increased appetite is not typically associated with dehydration but can be seen in other conditions. Warm, dry skin may be a sign of fever or other skin conditions, not specifically dehydration. Elevated blood pressure is not a common sign of dehydration in a child with diarrhea.
3. A child develops a strong dislike of noodle soup after consuming a bowl while sick with the flu. Her reaction is an example of a food-related ___.
- A. habit
- B. social interaction
- C. emotional turmoil
- D. negative association
Correct answer: D
Rationale: The correct answer is 'negative association.' A negative association occurs when a person develops a dislike for a food due to a past negative experience, such as getting sick after eating it. In this case, the child's dislike of noodle soup is specifically linked to the negative experience of consuming it while sick with the flu. Choices A, B, and C are incorrect because the situation described does not relate to habit formation, social interactions, or emotional turmoil, but rather to a learned aversion based on a specific negative event.
4. Approximately how many grams does a normal half-cup vegetable portion weigh?
- A. 5 grams
- B. 50 grams
- C. 100 grams
- D. 150 grams
Correct answer: C
Rationale: A normal half-cup vegetable portion usually weighs around 100 grams. This weight is a standard measurement for a half-cup serving of vegetables, making choice C the correct answer. Choices A, B, and D are incorrect as they do not align with the typical weight of a half-cup vegetable portion.
5. What type of vaccine should a child with a history of severe allergic reactions receive?
- A. Live attenuated vaccines
- B. Inactivated vaccines
- C. Subunit vaccines
- D. Recombinant vaccines
Correct answer: B
Rationale: Children with a history of severe allergic reactions should receive inactivated vaccines because they do not contain live pathogens. Live attenuated vaccines (choice A) contain weakened live pathogens and can potentially trigger an allergic reaction in sensitive individuals. Subunit vaccines (choice C) and recombinant vaccines (choice D) may contain components that could still trigger an allergic response in individuals with a history of severe allergies. Inactivated vaccines are the safest choice for individuals with a history of severe allergic reactions as they do not pose a risk of causing an allergic reaction due to the absence of live pathogens.
