1. Why is peer review important in scientific research?
- A. To expedite publication of results.
- B. To facilitate the replication of studies.
- C. To verify the accuracy and validity of research findings.
- D. To enhance the credibility of the research.
Correct answer: C
Rationale: Peer review is crucial in scientific research to verify the accuracy and validity of research findings. By subjecting research papers to evaluation by experts in the field, peer review ensures that the study's methods, results, and conclusions are robust and reliable. This process helps to maintain high standards of quality in scientific publications, providing credibility to the research. Choices A and D are incorrect because the primary purpose of peer review is not to expedite publication or solely enhance credibility; its core function is to validate the research's accuracy and validity. Choice B, while beneficial, is not the primary reason for peer review; replication is a byproduct of the rigorous evaluation of research methods and findings.
2. What is an important aspect of managing a child with ADHD?
- A. Increasing academic workload
- B. Consistent behavior management strategies
- C. Restricting all physical activity
- D. Encouraging solitary activities
Correct answer: B
Rationale: Consistent behavior management strategies are crucial when managing a child with ADHD. By implementing consistent strategies, such as clear rules, positive reinforcement, and structure, it helps the child improve focus, manage impulsivity, and regulate their behavior. Choice A, 'Increasing academic workload,' is incorrect as overwhelming a child with ADHD with more academic tasks can exacerbate their symptoms. Choice C, 'Restricting all physical activity,' is also incorrect as physical activity is beneficial for children with ADHD to release excess energy and improve focus. Choice D, 'Encouraging solitary activities,' is not ideal as social interaction and engagement with others are important for a child's development and well-being.
3. An essential nutrient is one that ___
- A. must be made in large quantities by the body
- B. can only be synthesized by the body
- C. cannot be made in sufficient quantities by the body
- D. is used to synthesize other compounds in the body
Correct answer: C
Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.
4. What should be assessed in an infant diagnosed with hypertrophic pyloric stenosis?
- A. Diarrhea after each feeding
- B. Gastric pain and vigorous crying
- C. Poor appetite due to poor sucking reflex
- D. An olive-shaped mass right of the midline
Correct answer: D
Rationale: In hypertrophic pyloric stenosis, an olive-shaped mass can often be palpated in the infant's abdomen, which is a hallmark sign of this condition. This mass is located in the right upper quadrant of the abdomen, right of the midline. Choices A, B, and C are incorrect because while infants with hypertrophic pyloric stenosis may experience vomiting (not diarrhea), gastric pain, and irritability, and have feeding difficulties, the key assessment finding specific to this condition is the palpable olive-shaped mass in the abdomen.
5. What is the primary symptom of a urinary tract infection in young children?
- A. Frequent urination
- B. Abdominal pain
- C. Vomiting
- D. Fever
Correct answer: D
Rationale: The correct answer is D, Fever. In young children, fever is a common primary symptom of a urinary tract infection, often accompanied by irritability and discomfort. Frequent urination (Choice A) is a symptom more commonly seen in adults with UTIs. While abdominal pain (Choice B) and vomiting (Choice C) can be present, they are not as primary as fever in young children with UTIs.
