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. In the scientific method, a tentative solution to a problem is called a what?

• A. theory
• B. prediction
• C. hypothesis
• D. correlation

Correct answer: C

Rationale: In the scientific method, a hypothesis is a tentative solution or educated guess that is tested through research. A theory (choice A) is a well-substantiated explanation based on evidence and extensive testing. A prediction (choice B) is a statement about what will happen in the future based on existing knowledge. Correlation (choice D) refers to a mutual relationship between two or more things, indicating how they may change together but not providing a solution to a problem.

3. How should pain be assessed in a nonverbal child?

• A. Ask the parents about the child’s usual behavior
• B. Observe the child’s facial expressions and body movements
• C. Measure the child’s blood pressure
• D. Use a pain rating scale for older children

Correct answer: B

Rationale: Observing the nonverbal child's facial expressions and body movements is crucial in assessing pain. Nonverbal children may not be able to communicate their discomfort verbally, making it essential to rely on physical cues. Asking parents about the child's usual behavior (choice A) may provide some insight but observing the child directly is more direct and reliable. Measuring blood pressure (choice C) is not typically a direct method for assessing pain in nonverbal children. Using a pain rating scale designed for older children (choice D) is also inappropriate for nonverbal children who cannot participate in such self-reporting tools.

4. What is one primary factor that influences nutrient needs in individuals?

• A. Age
• B. Gender
• C. Genetics
• D. Physical activity level

Correct answer: A

Rationale: Correct. Age is one of the primary factors influencing nutrient needs. Different life stages, such as infancy, childhood, adulthood, and old age, require varying amounts of nutrients. Gender (choice B) can influence nutrient needs to some extent, but age plays a more significant role. Genetics (choice C) may affect how individuals metabolize certain nutrients but is not a primary factor in determining overall nutrient needs. Physical activity level (choice D) can impact energy requirements but is not as fundamental as age in influencing overall nutrient needs.

5. What is a common symptom of an upper respiratory infection in children?

• A. Constipation
• B. Excessive vomiting
• C. Nasal congestion
• D. Abdominal pain

Correct answer: C

Rationale: Nasal congestion is a common symptom of an upper respiratory infection in children. It is typically accompanied by cough and sore throat. Constipation (choice A) and excessive vomiting (choice B) are not typical symptoms of upper respiratory infections. Abdominal pain (choice D) is more commonly associated with gastrointestinal issues rather than upper respiratory infections.
