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.'

What is one benefit of using controls in an experiment?
- A. The size of the groups does not matter.
- B. The subjects are unaware of the experiment's details.
- C. The subjects who are treated are balanced against the placebos.
- D. The subjects are similar in all respects except for the treatment being tested.
Correct Answer: D
Rationale: The correct answer is D. Controls in an experiment ensure that the subjects are similar in all respects except for the treatment being tested. This allows for a fair comparison between the treatment group and the control group. Choice A is incorrect because the size of the groups is not the primary benefit of using controls. Choice B is incorrect as blinding, not controls, refers to subjects not knowing about the experiment. Choice C is incorrect as it pertains more to randomization than the use of controls.
What is the primary goal in managing a child with chronic asthma?
- A. Achieve and maintain symptom control
- B. Avoid all physical activity
- C. Increase dietary sodium
- D. Restrict medication use
Correct Answer: A
Rationale: The primary goal in managing a child with chronic asthma is to achieve and maintain symptom control. This helps improve the child's quality of life by reducing asthma symptoms and exacerbations. Choice B is incorrect because avoiding all physical activity is not recommended for children with asthma; in fact, regular physical activity can be beneficial. Choice C is incorrect as increasing dietary sodium is not a primary goal in managing asthma. Choice D is incorrect because restricting medication use can lead to uncontrolled asthma symptoms and complications.
What is an important aspect of care for a child with congenital heart disease?
- A. Restricting physical activity
- B. Increasing fluid intake
- C. Administering high doses of vitamins
- D. Monitoring growth and development
Correct Answer: D
Rationale: Monitoring growth and development is crucial for children with congenital heart disease to ensure they are meeting developmental milestones and managing the disease effectively. This helps healthcare providers assess the child's overall health, detect any potential issues early, and adjust treatment plans accordingly. Restricting physical activity may not be necessary for all children with congenital heart disease and should be determined by their healthcare team based on individual needs. Increasing fluid intake and administering high doses of vitamins may not be directly related to managing congenital heart disease and should be guided by specific recommendations from healthcare providers.
What is a key aspect of care for a child with an indwelling urinary catheter?
- A. Increase fluid intake
- B. Monitor for signs of infection
- C. Restrict mobility
- D. Administer daily antibiotics
Correct Answer: B
Rationale: Monitoring for signs of infection is crucial when caring for a child with an indwelling urinary catheter. This is because catheter-associated urinary tract infections are common in such cases. Increasing fluid intake can be beneficial, but monitoring for infection takes precedence as it is crucial to prevent complications. Restricting mobility is not a key aspect of care for a child with an indwelling urinary catheter unless specifically advised by a healthcare provider. Administering daily antibiotics without proper assessment and indication can lead to antibiotic resistance and is not a standard practice in caring for a child with an indwelling urinary catheter.
What is an important dietary consideration for a child with celiac disease?
- A. Increased iron intake
- B. Gluten-free diet
- C. High-protein diet
- D. Low-sodium diet
Correct Answer: B
Rationale: A gluten-free diet is crucial for managing celiac disease in children because it helps prevent intestinal damage and alleviate symptoms. Gluten is a protein found in wheat, barley, and rye, and it triggers an immune response in individuals with celiac disease, damaging the lining of the small intestine. Therefore, choices A, C, and D are incorrect. While iron intake is important for overall health, a child with celiac disease can still meet their iron needs through sources that are naturally gluten-free or fortified. A high-protein diet or a low-sodium diet are not specifically required for managing celiac disease.
