1. 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.

2. What is the result of the metabolism of energy nutrients?

• A. Energy is released.
• B. Body fat increases.
• C. Energy is destroyed.
• D. Body water decreases.

Correct answer: A

Rationale: The correct answer is A. Energy is released during the metabolism of energy nutrients. This released energy is utilized by the body for various functions. Choice B is incorrect because the metabolism of energy nutrients does not directly result in an increase in body fat. Choice C is incorrect as energy is not destroyed but rather transformed and utilized by the body. Choice D is incorrect as the metabolism of energy nutrients does not lead to a decrease in body water.

3. What is the main function of proteins in the body?

• A. They provide structural components for the body.
• B. They assist in the absorption of vitamins.
• C. They help with the transport of nutrients in the blood.
• D. They help maintain fluid balance in the body.

Correct answer: A

Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).

4. What is a primary intervention for a child with a suspected respiratory infection?

• A. Administer antiviral medications
• B. Increase fluid intake and rest
• C. Restrict all physical activity
• D. Provide high-dose vitamin supplements

Correct answer: B

Rationale: Increasing fluid intake and rest is a primary intervention for a child with a suspected respiratory infection because it helps support the body’s recovery and maintains hydration levels. Antiviral medications (Choice A) are only used for specific viral infections and are not routinely recommended for suspected respiratory infections. Restricting physical activity (Choice C) may be necessary in certain cases to prevent overexertion, but it is not a primary intervention. Providing high-dose vitamin supplements (Choice D) may support the immune system in general but is not a primary intervention for a suspected respiratory infection.

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.
