Nutrition Final Exam
1. How should a healthcare professional manage a child with scabies?
- A. Use topical permethrin cream
- B. Administer oral antibiotics
- C. Apply topical antifungals
- D. Provide supportive care only
Correct answer: A
Rationale: Corrected Rationale: Topical permethrin cream is the appropriate treatment for scabies as it effectively kills the mites causing the infestation. Oral antibiotics are not indicated for scabies as it is not a bacterial infection. Topical antifungals are used to treat fungal infections, not scabies. Providing supportive care only would not address the underlying cause of scabies, which is the mite infestation.
2. What is one major weakness of a laboratory-based study?
- A. The costs are typically prohibitive.
- B. Findings are difficult to replicate.
- C. Results from animal testing cannot be applied to human beings.
- D. Experimental variables cannot be easily controlled.
Correct answer: C
Rationale: One major weakness of laboratory-based studies is that results from animal testing cannot always be applied to human beings. This limitation arises due to the inherent biological differences between animals and humans, making the generalization of findings challenging. While costs may be a concern in some cases, they do not represent a universal weakness of laboratory-based studies. Findings in such studies can be replicated to ensure validity, and experimental variables can be effectively controlled in a laboratory setting. Choice C is the correct answer because the translatability of results from animal studies to humans is a significant challenge in laboratory-based research, impacting the direct application of findings to human health and well-being.
3. What is a key aspect of managing a child with eczema?
- A. Daily baths with soap
- B. Regular use of emollients and moisturizers
- C. High-protein diet
- D. Frequent exposure to sunlight
Correct answer: B
Rationale: Regular use of emollients and moisturizers is a key aspect of managing eczema in children. Emollients help maintain skin hydration and reduce irritation, which are crucial in managing eczema symptoms. Daily baths with soap can actually worsen eczema by drying out the skin further. A high-protein diet and frequent exposure to sunlight are not directly related to managing eczema and may not have a significant impact on the condition.
4. Which statement is true of minerals in their role as nutrients?
- A. They are organic compounds.
- B. They yield 4 kilocalories per gram.
- C. Some become dissolved in body fluids.
- D. Some are destroyed during cooking.
Correct answer: C
Rationale: The correct statement is that some minerals become dissolved in body fluids, making them available for absorption and utilization by the body. Minerals are not organic compounds, so choice A is incorrect. Choice B is incorrect because minerals do not provide energy like macronutrients such as carbohydrates and fats. Choice D is incorrect because minerals are elements and cannot be destroyed by cooking; however, their availability and absorption may be affected by cooking methods.
5. By chemical analysis, what nutrient is present in the highest amounts in most foods?
- A. fats
- B. water
- C. proteins
- D. carbohydrates
Correct answer: B
Rationale: The correct answer is B. Water is the most abundant nutrient in many foods. Water content varies across different foods, but in general, it is present in the highest amounts. Fats (Choice A) are essential but are not found in higher amounts compared to water. Proteins (Choice C) and carbohydrates (Choice D) are also important nutrients, but they are typically found in lower quantities in most foods compared to water.
