1. 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.

2. 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.

3. How should a healthcare professional manage a child with a newly inserted gastrostomy tube?

• A. Monitor for signs of infection
• B. Increase the child's fluid intake
• C. Restrict all oral intake
• D. Use only sterile equipment for feedings

Correct answer: A

Rationale: Monitoring for signs of infection at the gastrostomy site is crucial for ensuring proper care and preventing complications. This involves observing for redness, swelling, warmth, or drainage around the insertion site. Increasing the child's fluid intake (Choice B) may be beneficial for hydration but is not specifically related to managing a newly inserted gastrostomy tube. Restricting all oral intake (Choice C) is not necessary as long as the healthcare professional follows the recommended guidelines for feeding. While using sterile equipment for feedings (Choice D) is important, monitoring for signs of infection takes precedence in the immediate post-insertion period.

4. What is a key aspect of managing a child with eczema?

• A. Daily baths with soap
• B. Regular use of emollients and moisturizers
• C. High-protein diet
• D. Frequent exposure to sunlight

Correct answer: B

Rationale: Regular use of emollients and moisturizers is a key aspect of managing eczema in children. Emollients help maintain skin hydration and reduce irritation, which are crucial in managing eczema symptoms. Daily baths with soap can actually worsen eczema by drying out the skin further. A high-protein diet and frequent exposure to sunlight are not directly related to managing eczema and may not have a significant impact on the condition.

5. What is a key sign of meningitis in an infant?

• A. Increased appetite
• B. Bulging fontanel
• C. Decreased respiratory rate
• D. Elevated blood pressure

Correct answer: B

Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.
