1. How should a healthcare professional handle a child with a new diagnosis of type 2 diabetes?

A. Focus on increasing physical activity and dietary management
B. Initiate insulin therapy immediately
C. Limit all carbohydrate intake
D. Recommend frequent fasting

Correct answer: A

Rationale: In managing type 2 diabetes in a child, focusing on increasing physical activity and dietary management is crucial, especially in the initial treatment phase. This approach helps improve insulin sensitivity and overall glycemic control. Initiating insulin therapy immediately is not the first-line treatment for type 2 diabetes in children. Limiting all carbohydrate intake is not advisable as carbohydrates are essential for providing energy and nutrients. Recommending frequent fasting can be harmful and is not a recommended strategy for managing type 2 diabetes in children.

2. How many minerals are known to be essential for human nutrition?

A. 8
B. 12
C. 16
D. 20

Correct answer: C

Rationale: There are 16 essential minerals required for human nutrition. These minerals include calcium, potassium, iron, and others. Choice A (8) is incorrect as it underestimates the number of essential minerals. Choice B (12) is also incorrect as it does not encompass the full count of essential minerals. Choice D (20) is incorrect as it overestimates the number of essential minerals.

3. What is critical for preventing complications in an infant with hypothyroidism?

A. Excessive growth
B. Cognitive impairment
C. Damage to the nervous system
D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. In infants with hypothyroidism, prompt administration of oral thyroid hormone replacement is crucial to prevent cognitive impairment and other serious complications. Excessive growth (choice A) is not a typical complication of hypothyroidism in infants. While hypothyroidism can affect the nervous system (choice C), cognitive impairment is more specific to untreated cases. Damage to the urinary system (choice D) is not a common complication of hypothyroidism in infants.

4. 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.

5. Why is randomization important in a scientific experiment?

A. To minimize the impact of confounding variables.
B. To eliminate bias in the assignment of subjects to groups.
C. To contribute to the accuracy and validity of the experiment's results.
D. To prevent systematic differences between groups.

Correct answer: B

Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.
