1. 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.'

2. What is one major weakness of a laboratory-based study?

• A. The costs are typically prohibitive.
• B. Findings are difficult to replicate.
• C. Results from animal testing cannot be applied to human beings.
• D. Experimental variables cannot be easily controlled.

Correct answer: C

Rationale: One major weakness of laboratory-based studies is that results from animal testing cannot always be applied to human beings. This limitation arises due to the inherent biological differences between animals and humans, making the generalization of findings challenging. While costs may be a concern in some cases, they do not represent a universal weakness of laboratory-based studies. Findings in such studies can be replicated to ensure validity, and experimental variables can be effectively controlled in a laboratory setting. Choice C is the correct answer because the translatability of results from animal studies to humans is a significant challenge in laboratory-based research, impacting the direct application of findings to human health and well-being.

3. What is the recommended daily intake of fiber for adults?

• A. 10 grams
• B. 15 grams
• C. 20 grams
• D. 25 grams

Correct answer: D

Rationale: The recommended daily intake of fiber for adults is 25 grams. Fiber plays a crucial role in maintaining digestive health, preventing constipation, and aiding in weight management. Options A (10 grams), B (15 grams), and C (20 grams) are incorrect as they are below the recommended daily intake of fiber for adults, which is 25 grams.

4. How should the nurse manage a child with acute lymphoblastic leukemia (ALL) who is receiving chemotherapy?

• A. Avoid all physical activity
• B. Ensure strict infection control measures
• C. Increase daily caloric intake
• D. Limit fluid intake

Correct answer: B

Rationale: The correct answer is B: Ensure strict infection control measures. Children with acute lymphoblastic leukemia (ALL) who are undergoing chemotherapy have compromised immune systems, making them highly susceptible to infections. Implementing strict infection control measures, such as hand hygiene, limiting exposure to sick individuals, and maintaining a clean environment, is essential to prevent infections. Choice A is incorrect because avoiding all physical activity may not be necessary as long as the child's activity level is appropriate. Choice C is incorrect because increasing daily caloric intake is important to support the child's nutritional needs during treatment. Choice D is incorrect because limiting fluid intake is not typically recommended unless specifically advised by the healthcare provider.

5. What is the primary treatment for a child with an anaphylactic reaction?

• A. Oral antihistamines
• B. Intravenous fluids
• C. Epinephrine injection
• D. Antipyretics

Correct answer: C

Rationale: The correct answer is C: Epinephrine injection. An epinephrine injection is the primary treatment for an anaphylactic reaction in children. Epinephrine acts quickly to reverse severe symptoms such as difficulty breathing, low blood pressure, and hives. Oral antihistamines, although useful for milder allergic reactions, are not sufficient to manage the potentially life-threatening symptoms of anaphylaxis. Intravenous fluids may be necessary to support blood pressure in a child with anaphylaxis but are not the primary treatment. Antipyretics, on the other hand, are medications used to reduce fever and are not indicated as the primary treatment for an anaphylactic reaction.
