Nutrition Final Exam Quizlet

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.

Correct Answer: C

Rationale: The correct answer is C: Chronic sinusitis. Untreated asthma can lead to chronic sinusitis in children due to prolonged inflammation and infection of the respiratory tract. Choices A, B, and D are incorrect. Delayed puberty and growth retardation are not common complications of untreated asthma in children. Frequent headaches may be associated with asthma exacerbations but are not typical long-term complications.

Correct Answer: C

Rationale: The correct long-term complication of cleft lip and palate is faulty dentition. Individuals with cleft lip and palate may experience dental issues such as missing, extra, or misaligned teeth, which can affect speech and the aesthetic appearance of the mouth. Cognitive impairment, as mentioned in choice A, is not a typical long-term complication associated with cleft lip and palate. While altered growth and development (choice B) can be affected during early stages, it is not a prominent long-term complication. Choice D, physical abilities, is not directly related to the typical long-term complications of cleft lip and palate.

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.

Correct Answer: B

Rationale: The primary goal in managing a child with cystic fibrosis is to prevent lung infections. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which increases the risk of infections. Preventing lung infections through proper respiratory care, medications, airway clearance techniques, and vaccinations is crucial in managing cystic fibrosis. While dietary interventions like increasing dietary fat intake, ensuring high protein intake, and promoting physical activity are also important aspects of cystic fibrosis management, preventing lung infections takes precedence as it directly addresses a major complication of the condition.
