1. What is the main purpose of Recommended Dietary Allowances (RDAs)?

• A. To provide guidelines for nutrient intakes that meet the needs of most healthy people.
• B. To specify the minimum amount of nutrients required for survival.
• C. To establish maximum safe levels of nutrient intakes.
• D. To recommend specific nutrient intake levels to prevent chronic diseases.

Correct answer: A

Rationale: The main purpose of Recommended Dietary Allowances (RDAs) is to provide guidelines for nutrient intakes that meet the needs of most healthy people. Choice B is incorrect because RDAs aim beyond just survival requirements. Choice C is incorrect because establishing maximum safe levels is the role of Tolerable Upper Intake Levels (ULs). Choice D is incorrect because preventing chronic diseases is more associated with Dietary Reference Intakes (DRIs) like Adequate Intakes (AIs) and Tolerable Upper Intake Levels (ULs). Therefore, the correct answer is A.

2. What is a common side effect of the antibiotic tetracycline in children?

• A. Discoloration of teeth
• B. Increased appetite
• C. Elevated blood glucose levels
• D. Decreased bone density

Correct answer: A

Rationale: Discoloration of teeth is a well-known side effect of tetracycline, especially when administered to children below 8 years of age. Tetracycline can bind to calcium ions in developing teeth, causing them to become discolored and appear yellow or brown. Increased appetite, elevated blood glucose levels, and decreased bone density are not commonly associated with the use of tetracycline in children, making them incorrect choices.

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 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.

5. Food energy is commonly expressed in kilocalories and in what other unit?

• A. kilojoules
• B. kilograms
• C. kilometers
• D. kilonewtons

Correct answer: A

Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.
