1. How does a double-blind experiment work?

• A. Both subject groups take turns receiving each treatment.
• B. Neither subjects nor researchers know which subjects are in the control or experimental group.
• C. Neither group of subjects knows whether they are in the control or experimental group, but the researchers do not know.
• D. Both subject groups know whether they are in the control or experimental group, but the researchers do not know.

Correct answer: B

Rationale: The correct answer is B. In a double-blind experiment, neither the subjects nor the researchers know which subjects are in the control or experimental group. This helps to eliminate bias and ensure that the results are more objective. Choice A is incorrect as in a double-blind experiment, subjects do not take turns receiving each treatment; it is about masking the treatment allocation. Choice C is incorrect because it implies that the researchers are aware of the group allocation, which goes against the principle of blinding in a double-blind study. Choice D is incorrect as both subject groups should not know whether they are in the control or experimental group to maintain the blindness of the study.

2. What should be a priority for a 4-year-old child with nephrosis?

• A. Impaired body image
• B. Skin impairment
• C. Nutritional deficit
• D. Injury

Correct answer: B

Rationale: The correct answer is B: Skin impairment. Skin care is a priority in nephrosis due to edema and increased risk of skin breakdown, requiring careful monitoring and management. While impaired body image (Choice A) can be a concern, it is not typically a priority in a 4-year-old with nephrosis. Nutritional deficit (Choice C) is important but addressing skin impairment takes precedence due to the immediate risk of complications related to skin breakdown. Injury (Choice D) is a general concern for children but is not the priority in a child with nephrosis.

3. What is an important consideration when administering medications to a child with hepatic dysfunction?

• A. Increased dosing intervals
• B. Adjustments in dosage due to altered metabolism
• C. Avoid all medications
• D. Use only topical medications

Correct answer: B

Rationale: When administering medications to a child with hepatic dysfunction, it is crucial to make adjustments in dosage due to altered metabolism. Hepatic dysfunction can affect the way medications are metabolized in the body, potentially leading to drug toxicity or reduced effectiveness. This is why adjusting the dosage is essential to ensure the medication is both safe and efficient. Choices A, C, and D are incorrect because increasing dosing intervals, avoiding all medications, or using only topical medications do not address the specific issue of altered drug metabolism in hepatic dysfunction.

4. 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).

5. In what units are energy measurements expressed by most scientists and nutritionists outside the United States?

• A. newtons
• B. liters
• C. kilojoules
• D. kilocalories

Correct answer: C

Rationale: Kilojoules are the standard units of energy used by most scientists and nutritionists worldwide. Newtons are units of force, liters are units of volume, and kilocalories are more commonly used in the United States but not as widely adopted internationally for energy measurements. Therefore, the correct answer is 'kilojoules.'
