Nutrition Final Exam
1. How much energy is required to raise the temperature of one kilogram of water by 1°C?
- A. 10 calories
- B. 100 calories
- C. 1 kilocalorie
- D. 10 kilocalories
Correct answer: C
Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.
2. Which individual is making a food choice based on negative association?
- A. A tourist from China who rejects a hamburger due to unfamiliarity
- B. A child who spits out his mashed potatoes because they taste too salty
- C. A teenager who grudgingly accepts an offer for an ice cream cone to avoid offending a close friend
- D. An elderly gentleman who refuses a peanut butter and jelly sandwich because he considers it a child's food
Correct answer: D
Rationale: Choice D is the correct answer because the elderly gentleman is refusing the peanut butter and jelly sandwich due to his negative association of considering it a child's food. This negative association influences his food choice. Choices A, B, and C do not involve negative associations with the food being consumed. Choice A is based on unfamiliarity, Choice B is due to taste preference, and Choice C is driven by social considerations rather than negative food association.
3. How should a healthcare provider approach the care of a child with juvenile idiopathic arthritis (JIA)?
- A. Promote weight maintenance
- B. Encourage joint mobility exercises
- C. Avoid physical inactivity
- D. Ensure a balanced diet
Correct answer: B
Rationale: Encouraging joint mobility exercises is the appropriate approach to caring for a child with juvenile idiopathic arthritis (JIA). These exercises help maintain joint function and reduce stiffness, which are crucial in managing the condition. Choices A, C, and D are incorrect. Promoting weight maintenance is more relevant than weight gain as maintaining a healthy weight is important in managing JIA. Avoiding physical inactivity is not recommended as controlled and appropriate physical activities can help improve joint flexibility and overall health. Ensuring a balanced diet, which includes adequate protein, is important for overall nutrition but is not a specific intervention for managing JIA.
4. 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.
5. 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.
