Correct Answer: B

Rationale: Choice B is the correct answer. A poor diet can increase the risk of developing chronic diseases due to the lack of essential nutrients or the presence of harmful components like excessive sugar, salt, or saturated fats. While diet plays a significant role in the development of chronic diseases, it is not the sole cause (choice C). Choice A is incorrect because diet does indeed have a significant impact on chronic diseases. Choice D is not the best answer as it does not acknowledge the negative impact of a poor diet on chronic diseases.

Correct Answer: D

Rationale: In acute laryngotracheobronchitis, rapid respirations increase the risk of aspiration due to compromised airway protection and potential for secretions to enter the lungs. Keeping the child NPO helps prevent the risk of aspiration pneumonia. Choice A is incorrect because epinephrine is not typically used for laryngotracheobronchitis. Choice B is incorrect as hydration with IV fluids does not eliminate the risk of aspiration. Choice C is also incorrect because the child being hungry is not the primary reason for keeping them NPO in this condition.

Correct Answer: C

Rationale: The correct answer is C: Antibiotics. Antibiotics are the primary treatment for acute otitis media because the condition is often caused by a bacterial infection. Antihistamines (choice A) and nasal decongestants (choice B) are not the primary treatments for acute otitis media as they do not target the bacterial infection. Ear drops (choice D) are not the primary treatment for acute otitis media; antibiotics are required to treat the underlying bacterial cause.

Correct Answer: A

Rationale: The correct answer is A: peer review. Before publication, research findings must undergo peer review, where experts in the field evaluate the validity and significance of the study. Choice B, cohort review, is incorrect as it does not involve the same level of evaluation by experts. Choice C, research intervention, is not a term used to describe the evaluation process before publication. Choice D, double-blind examination, refers to a study design where neither the participants nor the researchers know who is receiving a particular treatment, which is not the same as the peer review process.

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.
