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. How should a healthcare provider respond to a parent concerned about their child's frequent ear infections?

• A. Recommend over-the-counter ear drops
• B. Suggest an ENT specialist evaluation
• C. Advise on increasing fluid intake
• D. Encourage more physical exercise

Correct answer: B

Rationale: When a parent expresses concerns about their child's frequent ear infections, suggesting an ENT specialist evaluation is the most appropriate response. This specialist can conduct a thorough examination to identify the underlying cause of the recurrent infections and recommend the most suitable treatment. Recommending over-the-counter ear drops (Choice A) may not address the root cause of the issue and could potentially lead to inappropriate treatment. Advising on increasing fluid intake (Choice C) and encouraging more physical exercise (Choice D) are unrelated to addressing the specific concern of frequent ear infections.

3. How should a healthcare provider address a child's nutritional needs with a lactose intolerance diagnosis?

• A. Recommend lactose-free dairy products
• B. Increase dairy intake
• C. Encourage high-fiber diet
• D. Use oral probiotics only

Correct answer: A

Rationale: In managing lactose intolerance in a child, recommending lactose-free dairy products is crucial. These products help address the child's nutritional needs without causing symptoms related to lactose consumption. Choice B is incorrect because increasing dairy intake would exacerbate symptoms in a lactose-intolerant individual as they cannot digest lactose properly. Choice C, encouraging a high-fiber diet, is not directly related to managing lactose intolerance and may not address the primary issue of lactose malabsorption. Choice D, using oral probiotics only, may not be sufficient to address the child's nutritional needs in case of lactose intolerance as the main concern is avoiding lactose-containing products.

4. What is the term for the study of how diet affects gene expression?

• A. Epigenetics
• B. Nutrigenomics
• C. Genomics
• D. Genetics

Correct answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.

5. What is a common sign of hypothyroidism in children?

• A. Weight loss
• B. Increased heart rate
• C. Dry skin and constipation
• D. Elevated blood pressure

Correct answer: C

Rationale: Dry skin and constipation are typical signs of hypothyroidism in children. Hypothyroidism results from an underactive thyroid gland, leading to symptoms such as dry skin and constipation. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the thyroid gland is overactive. Increased heart rate (Choice B) and elevated blood pressure (Choice D) are also more characteristic of hyperthyroidism rather than hypothyroidism. Therefore, the correct answer is dry skin and constipation (Choice C) when identifying signs of hypothyroidism in children.
