1. 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.

2. What is the result of the metabolism of energy nutrients?

• A. Energy is released.
• B. Body fat increases.
• C. Energy is destroyed.
• D. Body water decreases.

Correct answer: A

Rationale: The correct answer is A. Energy is released during the metabolism of energy nutrients. This released energy is utilized by the body for various functions. Choice B is incorrect because the metabolism of energy nutrients does not directly result in an increase in body fat. Choice C is incorrect as energy is not destroyed but rather transformed and utilized by the body. Choice D is incorrect as the metabolism of energy nutrients does not lead to a decrease in body water.

3. What action should be taken for a 2-year-old with laryngotracheobronchitis in an oxygen tent?

• A. Restrain the child and notify the healthcare provider
• B. Increase the oxygen concentration
• C. Take the child to the playroom
• D. Ask the mother to help in comforting the child

Correct answer: B

Rationale: In laryngotracheobronchitis (croup), a child may become restless due to poor oxygenation. Increasing the oxygen concentration in the oxygen tent is crucial to improve oxygenation levels and manage symptoms effectively. Restraint is not appropriate in this situation, as it may cause distress and worsen the child's condition. Taking the child to the playroom is not indicated when the child requires oxygen therapy. While comforting the child is important, the priority in this scenario is to optimize oxygen delivery to improve respiratory distress.

4. 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.

5. What is a common sign of iron-deficiency anemia in children?

• A. Yellowing of the skin
• B. Pallor and fatigue
• C. Rapid weight gain
• D. Increased appetite

Correct answer: B

Rationale: Pallor and fatigue are common signs of iron-deficiency anemia in children. Iron-deficiency anemia is characterized by a decreased production of red blood cells, leading to a paler appearance (pallor) and increased fatigue due to reduced oxygen-carrying capacity. Yellowing of the skin (choice A) is more commonly associated with liver or bile duct issues. Rapid weight gain (choice C) and increased appetite (choice D) are not typical signs of iron-deficiency anemia.
