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 an important aspect of the care plan for a child with eczema?

• A. Use of steroid creams
• B. Frequent antibiotic therapy
• C. High-protein diet
• D. Daily baths in hot water

Correct answer: A

Rationale: The correct answer is A: Use of steroid creams. Steroid creams are commonly used in the management of eczema to reduce inflammation and itching, thus improving the skin condition and comfort of the child. Choice B, frequent antibiotic therapy, is incorrect as antibiotics are not typically used to treat eczema unless there is a secondary bacterial infection. Choice C, a high-protein diet, is not a specific recommendation for eczema treatment. Choice D, daily baths in hot water, is not recommended for eczema care as hot water can exacerbate the condition by drying out the skin.

3. Which nutrient is an organic compound?

• A. salt
• B. water
• C. calcium
• D. vitamin C

Correct answer: D

Rationale: Vitamin C is the correct answer because it is an organic compound containing carbon, which is a defining characteristic of organic compounds. Salt (choice A), water (choice B), and calcium (choice C) are inorganic compounds that do not contain carbon. Inorganic compounds are typically lacking carbon-hydrogen bonds, unlike organic compounds. Therefore, choices A, B, and C are incorrect in the context of being organic compounds.

4. 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.

5. How should the healthcare provider respond to a parent concerned about a child's short stature?

• A. Suggest the parent consult a nutritionist
• B. Recommend frequent growth hormone injections
• C. Advise monitoring for a few years before intervention
• D. Refer for a genetic evaluation

Correct answer: C

Rationale: When a parent expresses concern about a child's short stature, the initial approach should involve advising monitoring for a few years before considering any interventions. This allows for observation of the child's growth pattern and any potential underlying issues. Suggesting a nutritionist (Choice A) may not be necessary if there are no signs of nutritional deficiencies. Recommending growth hormone injections (Choice B) is premature without proper evaluation and diagnosis. Referring for a genetic evaluation (Choice D) can be considered later if monitoring shows atypical growth patterns or other concerning factors.
