Nutrition Final Exam Quizlet
1. What is a common symptom of an upper respiratory infection in children?
- A. Constipation
- B. Excessive vomiting
- C. Nasal congestion
- D. Abdominal pain
Correct answer: C
Rationale: Nasal congestion is a common symptom of an upper respiratory infection in children. It is typically accompanied by cough and sore throat. Constipation (choice A) and excessive vomiting (choice B) are not typical symptoms of upper respiratory infections. Abdominal pain (choice D) is more commonly associated with gastrointestinal issues rather than upper respiratory infections.
2. What will the treatment for a newly admitted child with cystic fibrosis center on?
- A. Chest physiotherapy
- B. Mucus-drying agents
- C. Prevention of diarrhea
- D. Insulin therapy
Correct answer: A
Rationale: The correct answer is A: Chest physiotherapy. Treatment for cystic fibrosis focuses on chest physiotherapy and aerosol medications to manage and clear thick pulmonary secretions. Chest physiotherapy helps loosen and clear mucus from the lungs, aiding in breathing and reducing the risk of infections. Mucus-drying agents (choice B) are not typically used in the treatment of cystic fibrosis as the goal is to help clear mucus, not dry it. Prevention of diarrhea (choice C) is not a primary focus in the treatment of cystic fibrosis. Insulin therapy (choice D) is not relevant to cystic fibrosis, which primarily affects the respiratory and digestive systems.
3. 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.
4. What is a key intervention for a child with a new diagnosis of asthma?
- A. Provide a peak flow meter
- B. Limit all physical activity
- C. Increase dairy consumption
- D. Recommend frequent use of nasal decongestants
Correct answer: A
Rationale: The correct answer is A: Provide a peak flow meter. Providing a peak flow meter is crucial for a child with a new diagnosis of asthma as it helps monitor asthma control and manage symptoms by tracking changes in airflow. This device assists in assessing how well the lungs are functioning and guides treatment decisions. Limiting all physical activity (choice B) is not recommended as regular exercise can actually help improve lung function in asthmatic children. Increasing dairy consumption (choice C) is not a key intervention for asthma, and recommending frequent use of nasal decongestants (choice D) is not suitable for asthma management in children.
5. 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.
