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. Which statement best describes the composition of most foods?

• A. Most foods contain a mixture of the three energy nutrients, with one or two predominating.
• B. Foods do not typically contain equal amounts of the three energy nutrients.
• C. Most foods contain mixtures of the three energy nutrients, although only one or two may predominate.
• D. Most foods contain all three energy nutrients in varying amounts.

Correct answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.

3. What is the term for the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius?

• A. Calorie
• B. Joule
• C. Kilojoule
• D. Kilocalorie

Correct answer: D

Rationale: The correct answer is D, Kilocalorie. The term kilocalorie, often referred to as a calorie, is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. While Choice A, Calorie, is technically correct, it is not the most specific term for the described amount of heat. Choice B, Joule, is a unit of energy but not specifically related to the amount of heat required to raise the temperature of water. Choice C, Kilojoule, is also a unit of energy but not the precise term for the heat required to raise the temperature of water by one degree Celsius.

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. After surgical repair of a cleft palate, what should be used to prevent injury to the suture line?

• A. Straw
• B. Spoon
• C. Syringe
• D. Cup

Correct answer: C

Rationale: The correct answer is C: Syringe. Using a syringe helps in feeding without causing injury to the suture line after cleft palate repair because it avoids direct contact with the suture area. Straws and spoons can potentially put pressure on the suture line, leading to injury. Cups may not provide the necessary control to prevent contact with the suture line, unlike a syringe.
