1. 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.

2. What does a positive correlation between two variables indicate?

• A. One variable causes the other.
• B. Both variables move in the same direction.
• C. Both variables move in opposite directions.
• D. There is no relationship between the variables.

Correct answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.

3. What is an important aspect of managing a child with ADHD?

• A. Increasing academic workload
• B. Consistent behavior management strategies
• C. Restricting all physical activity
• D. Encouraging solitary activities

Correct answer: B

Rationale: Consistent behavior management strategies are crucial when managing a child with ADHD. By implementing consistent strategies, such as clear rules, positive reinforcement, and structure, it helps the child improve focus, manage impulsivity, and regulate their behavior. Choice A, 'Increasing academic workload,' is incorrect as overwhelming a child with ADHD with more academic tasks can exacerbate their symptoms. Choice C, 'Restricting all physical activity,' is also incorrect as physical activity is beneficial for children with ADHD to release excess energy and improve focus. Choice D, 'Encouraging solitary activities,' is not ideal as social interaction and engagement with others are important for a child's development and well-being.

4. What is an important nursing intervention for a child with a newly inserted central venous catheter?

• A. Regularly monitor for signs of infection
• B. Administer intravenous fluids only as ordered
• C. Restrict the child's movement
• D. Perform daily dressing changes only

Correct answer: A

Rationale: Regularly monitoring for signs of infection is a critical nursing intervention for a child with a newly inserted central venous catheter. This intervention is essential to detect any early signs of infection, such as redness, swelling, or drainage at the catheter site, which can lead to serious complications like sepsis. Administering intravenous fluids as ordered is important but not the most crucial intervention for a newly inserted central venous catheter. Restricting the child's movement is unnecessary unless specified by the healthcare provider. Performing daily dressing changes alone is not sufficient to ensure the catheter's integrity and the child's safety; monitoring for signs of infection is key.

5. Which nutrient is classified as a micronutrient?

• A. minerals
• B. proteins
• C. alcohols
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.
