1. What does the term 'essential nutrient' refer to?

A. A nutrient that can be synthesized by the body.
B. A nutrient that is required for proper body functioning.
C. A nutrient that must be obtained from the diet because the body cannot produce it.
D. A nutrient that can be stored in the body for long periods.

Correct answer: C

Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.

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

A. Vitamins are organic compounds.
B. Vitamins provide energy.
C. Vitamins are considered micronutrients.
D. Vitamins are essential in small amounts.

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.

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

A. Provide clear and age-appropriate information
B. Avoid discussing the diagnosis
C. Refer to a specialist immediately
D. Suggest seeking alternative therapies

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.

4. What is the main purpose of the initial assessment of a child with a suspected fracture?

A. To determine the type of fracture
B. To check for potential complications
C. To identify the cause of the injury
D. To plan for long-term rehabilitation

Correct answer: B

Rationale: The main purpose of the initial assessment of a child with a suspected fracture is to check for potential complications, such as neurovascular impairment, and to ensure appropriate treatment. Choice A is incorrect because determining the type of fracture usually requires imaging studies like X-rays, which may not be part of the initial assessment. Choice C is incorrect because identifying the cause of the injury is important for the history-taking part but may not be the main purpose of the initial assessment. Choice D is incorrect because long-term rehabilitation planning typically occurs after the acute phase of fracture management.

5. Which of the following is an example of a macronutrient?

A. Vitamin C
B. Iron
C. Calcium
D. Fiber

Correct answer: D

Rationale: The correct answer is D: Fiber. Macronutrients are nutrients required by the body in larger amounts, and they include carbohydrates, proteins, and fats. Fiber is a type of carbohydrate that falls under this category. Vitamin C (choice A) is a water-soluble vitamin, Iron (choice B) is a mineral, and Calcium (choice C) is also a mineral, not a macronutrient. Therefore, Fiber is the only macronutrient listed in the choices.
