1. What is one characteristic that differentiates vitamins from minerals?

Correct answer: A

Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.

2. How should a child with a newly diagnosed seizure disorder be managed?

Correct answer: B

Rationale: When managing a child with a newly diagnosed seizure disorder, it is essential to monitor for triggers and ensure safety. By identifying triggers such as lack of sleep, stress, or specific foods, healthcare professionals can help prevent seizures. Ensuring safety involves creating a safe environment to prevent injuries during a seizure. Choices A, C, and D are incorrect. Avoiding all physical activity can be detrimental as appropriate exercise is essential for overall health. Increasing dietary sodium intake is not a standard recommendation for managing seizures. Restricting all forms of social interaction is unnecessary and can have negative effects on the child's emotional well-being.

3. How much energy is required to raise the temperature of one kilogram of water by 1°C?

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.

4. What type of nutrient is needed by the body and must be supplied by foods?

Correct answer: D

Rationale: The correct answer is D, essential nutrient. Essential nutrients are substances that the body needs for normal functioning but cannot produce in sufficient amounts, so they must be obtained through the diet. Nutraceuticals (choice A) are products derived from food sources that are purported to provide extra health benefits beyond basic nutrition. Metabolic nutrients (choice B) and organic nutrients (choice C) are not standard terms used to describe nutrients needed by the body. Therefore, choices A, B, and C are incorrect.

5. How should a healthcare provider address a child's concerns about a new medical diagnosis?

Correct answer: A

Rationale: Correct answer: Providing clear and age-appropriate information is crucial when addressing a child's concerns about a new medical diagnosis. Children often feel anxious and confused when faced with health issues, so offering them information in a way they can understand helps alleviate their fears and empowers them to cope better. Choice B is incorrect because avoiding discussing the diagnosis can lead to increased anxiety and uncertainty in the child. Choice C is incorrect as referring to a specialist immediately may not be necessary at the initial stage of addressing the child's concerns. Choice D is incorrect as suggesting alternative therapies without providing proper information about the medical diagnosis may not be suitable or effective.
