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. By chemical analysis, what nutrient is present in the highest amounts in most foods?

• A. fats
• B. water
• C. proteins
• D. carbohydrates

Correct answer: B

Rationale: The correct answer is B. Water is the most abundant nutrient in many foods. Water content varies across different foods, but in general, it is present in the highest amounts. Fats (Choice A) are essential but are not found in higher amounts compared to water. Proteins (Choice C) and carbohydrates (Choice D) are also important nutrients, but they are typically found in lower quantities in most foods compared to water.

3. What is a primary goal in managing a child with asthma?

• A. Avoiding all physical activities
• B. Achieving and maintaining control of asthma symptoms
• C. Increasing daily sugar intake
• D. Restricting all forms of medication

Correct answer: B

Rationale: The primary goal in managing a child with asthma is to achieve and maintain control of asthma symptoms to ensure the child's well-being and quality of life. This involves using appropriate medications as prescribed, identifying and avoiding triggers, and developing an asthma action plan. Choices A, C, and D are incorrect because avoiding all physical activities can lead to deconditioning and is not recommended, increasing daily sugar intake is unrelated to managing asthma, and restricting all forms of medication can be harmful as medications are often necessary to control asthma symptoms.

4. What is a common early sign of RSV (respiratory syncytial virus) in infants?

• A. High fever
• B. Nasal congestion
• C. Rash
• D. Jaundice

Correct answer: B

Rationale: Nasal congestion is a common early sign of RSV in infants, often accompanied by cough and wheezing. High fever, rash, and jaundice are not typically associated with RSV. While RSV can lead to fever, it is usually not one of the earliest signs. Rash and jaundice are unrelated to RSV symptoms.

5. What is the term for the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius?

• A. Calorie
• B. Joule
• C. Kilojoule
• D. Kilocalorie

Correct answer: D

Rationale: The correct answer is D, Kilocalorie. The term kilocalorie, often referred to as a calorie, is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. While Choice A, Calorie, is technically correct, it is not the most specific term for the described amount of heat. Choice B, Joule, is a unit of energy but not specifically related to the amount of heat required to raise the temperature of water. Choice C, Kilojoule, is also a unit of energy but not the precise term for the heat required to raise the temperature of water by one degree Celsius.
